Little Size SEMS Screw Composed of Allen Cap Head Screw, a Flat Wahser & a Spring

 Washer

 

 

Hex socket combination screws are usually composed of hex socket cup head screws, and the spring washer is fastened together with the flat washer. The cylindrical head hexagon socket combination screw is widely used among all screws and has relatively high requirements. The advantage is that the fastening force is relatively large, and it can be operated with an hexagon wrench. It is very convenient to install and can be used in almost all structures. The appearance is beautiful and neat. The disadvantage is that the fastening force is slightly lower than that of the outer hexagon. In addition, the hexagon socket is easily damaged by repeated use, making it impossible to disassemble.
