Professional Applications & Engineering Value

These 1/4-20 UNC steel weld studs are engineered to address critical challenges in industrial fastening applications where vibration resistance and consistent performance are paramount. The Class 3A thread fit ensures precise mating with corresponding components, eliminating play and maintaining alignment in machinery, structural frameworks, and heavy equipment assemblies. The fully threaded design with coarse UNC spacing provides maximum thread engagement across the entire 1 1/4" length, distributing load evenly and preventing stress concentration. The below-head projection configuration allows for optimal weld penetration and surface contact, crucial for automotive manufacturing, construction equipment, and industrial machinery where weld integrity directly impacts safety and operational reliability. The combination of 60,000 psi tensile strength and right-hand coarse threading makes these studs ideal for applications requiring both high load-bearing capacity and efficient installation in production environments.

Specification Summary & Compliance

These weld studs feature precision 1/4"-20 UNC coarse threads with Class 3A external thread fit per standard specifications, ensuring dimensional accuracy and reliable performance. The 0.575" base diameter and 0.083" base thickness provide optimal welding surface area and structural stability. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming adherence to current substance restriction requirements for industrial components. The fully threaded configuration with right-hand direction follows industry-standard UNC threading specifications for consistent compatibility with mating components.
