• 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. 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.

Stainless Steel 316 Machine Screw, Pan Head, Phillips Drive, #8-32, 1" Length (Pack of 25) Feature

• 316 stainless steel offers superior corrosion resistance compared to 302 and 304 stainless steels
• Suitable for a range of applications including harsh chemical-processing and marine environments, 316 stainless steel resists chemicals, solvents, and chlorides
• Pan head style has a lower profile than similar round and fillister styles but still protrudes above fastened material for easy installation and removal
• Phillips drive reduces risk of over-tightening to protect screw and fastened material
• Designed according to ANSI B18.6.3 standards

Choose 316 stainless steel machine screws when you need superior corrosion resistance to chemicals, solvents, and chlorides in a range of fastening applications including chemical-processing and marine environments.

Offering better corrosion resistance than both 302 and 304 stainless steels, 316 stainless steel contains molybdenum and higher amounts of chromium and nickel than other stainless steel alloys. These additional elements protect screws from pitting, a form of corrosion that creates holes in material. 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).

Pan head fasteners feature a lower profile than similar styles such as round and fillister heads but still protrude above fastened material for easy installation and removal. The cross-slotted Phillips drive style reduces risk of over-tightening. This design causes the driver to slip under too much force, protecting both the screw and the fastened material from damage. Screws are designed according to ANSI B18.6.3 standards, which specify dimensions including head diameter and height, slot width and depth, and driver size.

Machine screws, also referred to as machine bolts, often are used with nuts or driven into threaded holes in metal or composite materials. A threaded fastener's size includes information about the screw’s largest diameter, followed by the number of threads per inch, which indicates whether it is coarse (has fewer threads per inch) or fine (has more threads per inch). Coarse threading provides easier, faster assembly and is ideal for softer materials. Fine threading offers greater strength and works best with very hard materials or thin materials like sheet metal.

• Acetal is suitable where hardness and water resistance are important considerations
• Pan head allows for higher tightening torques
• 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.

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. 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.

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.

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.

• Machine Screws are often used with nuts or driven into tapped holes
• PTFE is suitable for high temperature environments and for applications that have the potential for surface wear and exposure to water and chemicals
• 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.

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).

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.
