Socket Head Shoulder screw

Socket Head Shoulder Screws


Description:

Socket head shoulder screws from ITA Fasteners are used in applications which require a decent tensile strength. They are used in the designing of shearing components and machines whose components require the space and ability to swing, oscillate or pivot. They are also used in punch and die applications. These screws are pressure and heat treated to support shear loads like stripper plates and printing presses.

The dimensional specifications of these screws are denoted by their shoulder diameter. The shoulder diameter comes with a default length and thread diameter. The thread diameter is one size smaller than the shoulder length. We have used precision design technology to control the critical dimensions of the under head bearing surface and its radius. The run-out thread section and its profile are also designed meticulously. Such efficient production methods make sure the quality of the screws is unsurpassed, making the structure built with it, sturdy. It is available in stainless steel, carbon steel, and alloy steel to bear more wear and tear while also making it more corrosion resistant.
