Professional Applications & Engineering Value

This 2-56 UNC stainless steel press-fit stud solves critical challenges in sheet metal assembly by combining 18-8 stainless steel durability with a precision press-fit design. Its fully threaded body and Class 2A thread fit ensure secure fastening in applications like electronics enclosures, automotive panels, and machinery frames, where vibration resistance and corrosion protection are paramount. The stud’s 0.129" base diameter and specified hole size (0.085") allow for rapid installation in materials as thin as 0.04", reducing labor time while eliminating the need for welding or adhesives. By maintaining right-hand coarse threading, it supports high-volume production lines and minimizes the risk of cross-threading, enhancing overall assembly efficiency and product longevity.
