Professional Applications & Engineering Value

This black-oxide steel hanger bolt delivers exceptional engineering value through its specialized UNC coarse thread configuration and right-hand thread direction, designed specifically for extension spring applications where consistent tension and reliable anchoring are critical. The coarse thread spacing provides superior resistance to vibration loosening while enabling quicker installation in industrial assembly lines. The black-oxide surface treatment creates a protective barrier against oxidation and environmental degradation, extending component lifespan in manufacturing facilities, automotive systems, and machinery where spring hardware must maintain integrity under cyclic loading conditions. The stud anchor design ensures direct, secure mounting without requiring additional fastening components, streamlining your assembly process while maintaining heavy-duty performance standards.

Specification Summary & Compliance

Manufactured to UNC coarse thread standards with Class 2A thread tolerances, this hanger bolt maintains precise dimensional accuracy with 0.138" diameter and 3/8" minimum thread length. The product fully complies with RoHS 3 (2015/863/EU) under exemption 6(a) for lead as an alloying element in steel and meets REACH (EC 1907/2006) compliance requirements as of January 17, 2023, ensuring regulatory adherence for industrial and international applications.
