Product Description
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.
Polyetheretherketone (PEEK) is a superpolymer, or high performance thermoplastic which has excellent chemical resistance and is rated for continuous service to 464 degrees Fahrenheit. It has the best fire safety rating of all thermoplastics. It can be radiation sterilized, tolerating radiation to 1100 M rads without undergoing significant change. The Peek used in these fasteners has been reinforced with 30% glass fibers which improves tensile strength to 22,600 psi (pounds per square inch.). Peek resists water absorption, absorbing 0.11% when exposed to water for 24 hours. Peek is extremely impact resistant, rated at 13.6 foot pounds (on the Izod Impact Scale), which compares favorably against Nylon 6/6 at 3 foot pounds. Peek is below average in terms of dielectric strength, for a plastic, with a rating of 175 volts/millimeter (compared to Nylon with a rating of 550 volts/millimeter).
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.
