--- **Product Description** Stainless Steel Hexagon Socket Head Cap Screw (DIN 912 8.8) A bolt is a type of threaded fastener with an external male thread. Bolts are often confused with screws due to their similar appearance and function. A hex cap screw is a type of cap screw that features a hexagonal head, designed to be tightened using a wrench or spanner. Hex cap screws, particularly those compliant with ASME B18.2.1, have tighter tolerances compared to standard hex bolts in terms of head height and shank length. This ensures that they can always fit where a hex bolt is used, while a hex bolt might be slightly too large for a hex cap screw application.
