• Machine Screws are often used with nuts or driven into tapped holes
• PVDF is suitable for applications that require high purity and low water absorption, along with greater strength than PTFE
• Flat head style allows fastener to sit flush to the surface
• Driven by a flat-bladed driver
• Coarse threads are better for brittle materials, and will assemble and disassemble more quickly than fine threads

Machine Screws, also referred to as Machine Bolts, are often used with nuts or driven into tapped holes. They come in a variety of head types and drive styles, but are generally available in smaller sizes.

Polyvinylidene Fluoride, or PVDF, has a useful temperature range of -148 to 300 degrees Fahrenheit. PVDF exhibits similar properties to Kynar, a trade name of the Arkema Corporation. PVDF is generally used in applications requiring high purity, strength, and resistance to solvents, acids, bases and heat. It also generates little smoke during a fire event. PVDF exhibits below average strength as compared to Nylon 6/6, with tensile strength ranging from 5000 to 7000 psi (pounds per square inch) and impact strength of 1.2 foot pounds (on the Izod Impact Scale) as compared to 9000 psi, and 3 foot pounds, respectively. PVDF is stronger than PTFE and could be desirable where PTFE is not strong enough for the application. PVDF will absorb little or no water after 24 hours of exposure (less than 0.05% of weight impact). PVDF also has below average dielectric strength of 260 volts per millimeter (compared to 500 volts/mm for Nylon).

Flat head fasteners are designed to fit flush to the surface when used with countersunk holes. Length is measured from the top of the head. Common applications for slotted screws include woodworking, although the drive style is not designed to be used with power drivers.

A threaded fastener's size name includes information about the major external diameter, followed by the threads per inch, which indicates if it is coarse or fine. Coarse threads are better when working with brittle materials; they are sturdier and are easier to thread and unthread compared to fine. Coarse threading also allows for thicker coatings and platings.

Polypropylene Machine Screw, Binding Head, Slotted Drive, 1/4"-20, 3/8" Length (Pack of 100) Feature

• Machine Screws are often used with nuts or driven into tapped holes
• Polypropylene is suitable for applications where resistance to chemicals and water (including steam) is important
• Binding head provides a large surface area for extra surface contact under the head
• Driven by a flat-bladed driver
• Coarse threads are better for brittle materials, and will assemble and disassemble more quickly than fine threads

Machine Screws, also referred to as Machine Bolts, are often used with nuts or driven into tapped holes. They come in a variety of head types and drive styles, but are generally available in smaller sizes.

Polypropylene is a thermoplastic which is autoclavable (meaning that it can be sterilized using steam), and is non-hydroscopic (it won't absorb water even after extended periods of contact). Polypropylene has excellent chemical resistance to dilute acids, concentrated acids (except oxidizing acids), alkalis, alcohols, detergents, and water. Polypropylene resists aromatic hydrocarbons, chlorinated hydrocarbons, greases, and oils at room temperature. Maximum operating temperature is 212 degrees Fahrenheit. Polypropylene has a low co-efficient of friction and a high dielectric strength (meaning it operates well as an insulator). Polypropylene has approximately half the tensile strength and impact strength of Nylon 6/6. The tensile strength of Polypropylene is 5000 psi (pounds per square inch). Impact Strength, as measured by the Izod impact test method (which measures force required to break material) is 0.5 pounds per foot.

Generally used in electrical or radio work, these fasteners are slightly undercut under the head. That provides the ability to bind stranded wire tightly and prevent fraying. Common applications for slotted screws include woodworking, although the drive style is not designed to be used with power drivers.

A threaded fastener's size name includes information about the major external diameter, followed by the threads per inch, which indicates if it is coarse or fine.

Machine Screws, also referred to as Machine Bolts, are often used with nuts or driven into tapped holes. They come in a variety of head types and drive styles, but are generally available in smaller sizes.

Acetal resins are characterized by their strength, stiffness, and hardness, and are stable over a wide range of temperatures, humidity, environments, and stress. Acetal has a low coefficient of friction, and absorbs little water, minimizing the effect of moisture on its physical properties. Acetal resists neutral oils, grease, petroleum-based fuels, many organic solvents, alkalis, oxidizing agents and acids, both organic and inorganic. Compared to Nylon 6/6, Acetal is harder and has better water resistance, but lower impact strength and abrasion resistance. Acetal is translucent off white in color.

Pan head fasteners have a low, large cylindrical head with a high rounded top edge for higher tightening torques - these fasteners are often recommended to replace older head styles such as round, binding, or truss-head where possible. Common applications for slotted screws include woodworking, although the drive style is not designed to be used with power drivers.

Machine Screws, also referred to as Machine Bolts, are often used with nuts or driven into tapped holes. They come in a variety of head types and drive styles, but are generally available in smaller sizes.

Stainless steels are used for their corrosion resistance, high-temperature strength, scaling resistance, and low-temperature toughness. These properties account for their extremely wide use in practically every industry. Austenitic Stainless Steels are alloys of iron and carbon that contain between 16% and 30% Chromium, a maximum of 0.15% carbon, along with Nickel (or Manganese), and other alloying elements. The chromium, which helps develop a passive surface oxide film, provides corrosion resistance in stainless steels. Austenitic Stainless Steels are designated by a 3 digit SAE Stainless Steel Grade beginning with the number 3 (e.g. 304, 316).

Stainless Steel 316 has a higher nickel and molybdenum content than most Austenitic stainless steels which means that this material offers more corrosion resistance without giving up strength or hardness. Tensile strength is 35,000 psi (pounds per square inch).

Flat head fasteners are designed to fit flush to the surface when used with countersunk holes. Length is measured from the top of the head. The Phillips drive style was originally designed so that the driver would slip out under extreme torque, preventing over-tightening and damage to the fastener or the material.

• Fillister head for high torque and good hold-down strength
• Phillips drive is designed to cam out under too much torque
• Coarse threads are better for brittle materials, and will assemble and disassemble more quickly than fine threads

Machine Screws, also referred to as Machine Bolts, are often used with nuts or driven into tapped holes. They come in a variety of head types and drive styles, but are generally available in smaller sizes.

Nylon 6/6 is a general purpose thermoplastic with outstanding resistance to organic chemicals, acids and alkalis. Nylon wears well against other surfaces; it is readily machinable and may be milled, turned and cut with conventional machine tools. It does exhibit some dimensional swelling in wet applications which should be taken into account with its use. Tensile strength of this material is 12,000 psi (pounds per square inch).

Fillister head fasteners are considered an improvement over round head equivalents - the smaller head creates more downward pressure for a given torque level and the thicker head plus deeper drive slot allows higher torque levels to be generated. The Phillips drive style was originally designed so that the driver would slip out under extreme torque, preventing over-tightening and damage to the fastener or the material.

A threaded fastener's size name includes information about the major external diameter, followed by the threads per inch, which indicates if it is coarse or fine. Coarse threads are better when working with brittle materials; they are sturdier and are easier to thread and unthread compared to fine.

PTFE (polytetrafluoroethylene) has similar properties to Teflon, including an extremely low coefficient of friction (it doesn't stick to other materials and it resists surface wear). PTFE also exhibits a useful service life from below -100 degrees Fahrenheit, to temperatures of over 500 degrees Fahrenheit. Its resistance to solvents is also excellent throughout a wide range of temperatures. PTFE has a high dielectric strength (600 volts/millimeter) which makes it a good insulator. PTFE is also very non-hydroscopic, or water resistant, absorbing less than 0.01% of its weight if exposed to water for a 24 hour period. PTFE has below average tensile strength, at 3000 psi (pounds per square inch).

Polyvinylchloride, or PVC, exhibits little or no water absorption, absorbing 0.05% of its weight after 24 hours of exposure to water. Because it is chlorinated, PVC also possesses natural flame retardant qualities. PVC has one of the highest dielectric strengths of plastics, at 1413 volts per millimeter, making it an excellent insulator. PVC possesses average to above average strength compared to other plastics, with a tensile strength of 7450 psi (pounds per square inch) and an impact strength of 5 force pounds (Izod Impact Scale). The primary drawback of PVC is its low melting point temperature of 140 degrees Fahrenheit.

• Driven by a flat-bladed driver
• Coarse threads are better for brittle materials, and will assemble and disassemble more quickly than fine threads

Machine Screws, also referred to as Machine Bolts, are often used with nuts or driven into tapped holes. They come in a variety of head types and drive styles, but are generally available in smaller sizes.

Nonconductive and resistant to many corrosives, Fiberglass is a good choice for applications threatened by salt water, oils, mild solvents, and other harsh environments. G-10 is a glass reinforced fiberglass, utilizing a continuous woven glass fabric laminated with an epoxy resin. The glass reinforcing increases tensile strength over non-reinforced fiberglass, G-10 in particular is rated at 38,000 psi (pounds per square inch range). G-10 exhibits a high tensile strength to weight ratio, approximately twice that of Aluminum 2024, for example. G-10 is very non-porous, and will only absorb 0.1% of water if left to soak for 24 hours. G-10 is flame retardant and will operate at temperatures up to 280 degrees without degrading. This material is recommended for applications where superior strength and excellent electrical insulative properties are required over a wide range of temperatures.

Pan head fasteners have a low, large cylindrical head with a high rounded top edge for higher tightening torques - these fasteners are often recommended to replace older head styles such as round, binding, or truss-head where possible. Common applications for slotted screws include woodworking, although the drive style is not designed to be used with power drivers.

A threaded fastener's size name includes information about the major external diameter, followed by the threads per inch, which indicates if it is coarse or fine. Coarse threads are better when working with brittle materials; they are sturdier and are easier to thread and unthread compared to fine. Coarse threading also allows for thicker coatings and platings.

Machine Screws, also referred to as Machine Bolts, are often used with nuts or driven into tapped holes. They come in a variety of head types and drive styles, but are generally available in smaller sizes.

Nylon 6/6 is a general purpose thermoplastic with outstanding resistance to organic chemicals, acids and alkalis. Nylon wears well against other surfaces; it is readily machinable and may be milled, turned and cut with conventional machine tools. It does exhibit some dimensional swelling in wet applications which should be taken into account with its use. Tensile strength of this material is 12,000 psi (pounds per square inch).

Pan head fasteners have a low, large cylindrical head with a high rounded top edge for higher tightening torques - these fasteners are often recommended to replace older head styles such as round, binding, or truss-head where possible. The Phillips drive style was originally designed so that the driver would slip out under extreme torque, preventing over-tightening and damage to the fastener or the material.
