Stainless Steel A2-70 DIN6921 with Serrated Hex Flange Bolt A bolt is a type of threaded fastener with an external male thread. It is often confused with screws, but bolts are typically used in conjunction with nuts to secure two or more components together. A hex cap screw, for example, has a hexagonal head and is designed to be driven by a wrench or spanner. ASME B18.2.1 compliant cap screws have tighter tolerances compared to hex bolts, making them more precise in fit and function. This means that while a hex cap screw can always fit where a hex bolt is installed, the reverse may not always be true.
