Screws are threaded fasteners used to position an object or to fasten two or more objects together. Essentra Components has a large selection of screws including slotted, Phillips head and knurled. We have steel, stainless steel and nylon screws. We have many common types, such as standard hex bolts, as well as many specialized types such as lock, captive and set screws.
In the strictest sense, screws are threaded fasteners that secure an object without the use of a nut. However, many bolts can be used as screws and vice versus.
