// Socket Head Cap Screw
// This is for a #10-24 screw that is 1.00 inches long. A socket head cap screw is a type of fastener that is widely used in a variety of applications requiring a high strength fastening solution. It is characterized by its cylindrical head and internal hexagonal drive, which allows for tightening with an Allen wrench or hex key.
