Socket Jam Screws
Socket jam screws are a type of screw with a hexagonal socket head that is designed to be tightened with a hex key or Allen wrench. The term "jam" refers to the fact that these screws are often used to secure two parts together tightly, preventing them from moving or slipping relative to each other.
Socket jam screws typically have a threaded shaft and a flat or rounded tip, and they may have a locking patch or a nylon insert to help prevent loosening over time. They are commonly used in a variety of applications, including in machinery, electronics, and woodworking.
