PVDF Machine Screw, Flat Head, Slotted Drive, 1/4"-20, 3/8" Length (Pack of 25) Feature

• 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.

Nylon 6/6 Machine Screw, Cheese Head, Slotted Drive, M6-1, 75mm Length (Pack of 50) Feature

• Machine Screws are often used with nuts or driven into tapped holes
• Nylon 6/6 is suitable where non-conductivity, corrosion resistance, and cost are important considerations
• Cheese head permits greater grip and driving power
• 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.

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).

Featuring a thick cylindrical head, cheese head style fasteners allow deeper grooves for driving, allowing greater driving force. 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 (in millimeters), followed by the thread pitch (millimeters per thread), 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 are often used with nuts or driven into tapped holes
• Nylon 6/6 is suitable where non-conductivity, corrosion resistance, and cost are important considerations
• Round head style for a finished appearance
• Driven by a flat-bladed driver
• Fine threads tap better into harder materials and thin walls, and are stronger in tension than coarse threads

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).

Round head fasteners have a dome-shaped head. An older style of head, it is typically used when replacing existing round-head fasteners where an exact match is desired. 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. Fine threads are preferable when working with harder materials or when threading into a thin material. They are also stronger in tension than coarse threads, and generally provide higher shear strengths.

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.
