About Nylon 6/6 Shoulder Screw, Plain
Shoulder screws, also known as shoulder bolts, are used for several different applications, including those that involve rotation or require a locking type of screw. Shoulder screws are distinct from other types of screws due to the fact that they are only partially threaded, leaving a smooth-sided shaft between the threading and the head. This shaft is usually slightly larger than the threaded portion of the screw. They are often used in automotive and mechanical applications. Nylon 6/6 is a general-purpose thermoplastic with high resistance to organic chemicals, acids, and alkalis. Nylon wears well against other surfaces. It does exhibit some dimensional swelling in wet applications which should be taken into account with its use. Color is off-white. Hex socket drive systems are driven by hex wrenches or power tools with hexagonal bits. A threaded fastener's size name includes information about the major external diameter, followed by the thread pitch, which indicates if it is coarse or fine.
