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
- 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
