Professional Applications & Engineering Value

This 1/4-20 UNC steel weld stud delivers exceptional performance in heavy-duty welding applications where structural integrity is paramount. The combination of 60,000 psi tensile strength and Class 3A thread precision addresses common industrial challenges including vibration loosening and mechanical stress failures. The fully threaded coarse UNC design provides superior pull-out resistance in metal fabrications, while the below-head projection ensures consistent weld penetration for permanent installations. Ideal for machinery assembly, structural steelwork, and equipment manufacturing, this welding stud maintains dimensional stability across thermal cycles and mechanical loads, reducing maintenance requirements and downtime in industrial operations.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 3A thread fit tolerance for external threads, this weld stud features 1/4"-20 UNC coarse threading with right-hand direction. The product maintains 0.575" base diameter and 7/8" length with consistent 0.083" base thickness. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility in industrial applications.
