Professional Applications & Engineering Value

This 4-40 UNC press-fit stud is engineered to solve common challenges in sheet metal assembly, where creating strong, reliable threaded points in thin materials can be difficult. Manufactured from 18-8 stainless steel, it provides excellent resistance to corrosion and oxidation, making it suitable for electronics enclosures, automotive components, and outdoor equipment. The fully threaded and right-hand design, combined with a Class 2A thread fit, ensures quick and secure fastening without cross-threading, reducing assembly errors and labor time. Its specified drill diameter of 0.111" and minimum edge distance help maintain structural integrity by preventing material deformation near sheet edges, delivering consistent performance in high-volume production environments.

Specification Summary & Compliance

This stud adheres to UNC coarse thread standards with a Class 2A thread fit for consistent dimensional accuracy. It is designed for a 0.111" hole diameter with a tight tolerance range, and requires a minimum material thickness of 0.04" and a minimum edge distance of 7/32". The product is manufactured in compliance with RoHS 3 (2015/863/EU), ensuring it meets stringent environmental regulations for hazardous substance restrictions.
