Professional Applications & Engineering Value

This 1/4"-20 UNC press-fit stud is engineered for high-strength, permanent fastening in metal sheets and enclosures. The zinc-plated steel material offers excellent durability against corrosion, while the fully threaded design and Class 2A thread fit ensure reliable torque resistance and alignment in automated assembly lines. It solves common issues like loose fittings and thread stripping by providing a tight press-fit with minimal hole preparation—using a standard 0.25" drill bit—making it ideal for electronics, machinery, and automotive components where vibration resistance and long-term stability are critical.

Specification Summary & Compliance

This stud features a base diameter of 0.352", length of 7/8", and is designed for a 0.249" hole diameter with tight tolerances (0.000" to 0.003"). Thread specifications include 1/4"-20 UNC coarse threads, right-hand direction, and Class 2A external thread fit per standard inch measurement systems. It complies with RoHS 3 (2015/863/EU) regulations, ensuring environmental safety in industrial applications.
