**Carbon Steel Stud Bolt A193-B7 in Black**
A bolt is a type of threaded fastener with an external male thread. Bolts are often confused with screws, but they are typically used with nuts and have coarser threads. A hex cap screw is a type of cap screw with a hexagonal head, designed to be driven by a wrench. An ASME B18.2.1 compliant cap screw has tighter tolerances than a standard hex bolt, making it more precise for specific applications.
