Product Description

1. Descriptions:

    

     Socket Head Cap Screw, Material 18-8 Stainless Steel, Plain, Drive Type Hex Socket and Thread Direction Right Hand; Varies by Head Type, Thread Dia., Thread Size and Length under Head Hex socket head cap screw, also known as the Allen bolt or allen head screw.

     Similar to the countersunk head screw, the head buried into the parts, which have the greater strength of the connection, using the proper size Allen wrench assembly and disassembly. The material are normally Alloy Steel, Stainless Steel and Carbon Steel.Socket head cap screws are ideal for precision work with close tolerances and applications whcih need a well tooled appearance.

 

      Socket head cap screws supply high tensile strength than equivalent hex head caps screws, meanwhile requiring less surface area to countersunk head screws.
