Set Screws are often used for holding a pulley, gear, or other parts from turning relative to a shaft.

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).

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.

Set Screws keep parts from turning relative to a shaft
Nylon 6/6 is suitable where non-conductivity, corrosion resistance, and cost are important considerations
Do not have an external head
Driven by a flat-bladed driver
Coarse threads are better for brittle materials, and will assemble and disassemble more quickly than fine threads
