Professional Applications & Engineering Value

These 8-36 UNF hanger bolts with black-oxide steel construction solve critical challenges in industrial fastening systems where corrosion resistance and precise thread engagement are paramount. The fine UNF threads maintain superior clamping force in extension spring applications, preventing loosening under dynamic loads and vibration. The stud anchor design provides dual-thread functionality, eliminating the need for multiple components in suspension systems. Black-oxide surface treatment creates a protective barrier against moisture and chemical exposure, significantly extending service life in manufacturing facilities, automotive assemblies, and machinery where environmental factors degrade ordinary fasteners. The combination of right-hand threading and precise 7/8" length ensures compatibility with standard installation tools and existing equipment designs.

Specification Summary & Compliance

Manufactured to UNF fine thread standards with Class 2A tolerance for consistent fit and performance. The 0.164" diameter and 5/8" minimum thread length ensure proper engagement in 0.1" diameter mounting holes. Compliant with RoHS 3 (2015/863/EU) under exemption 6(a) for lead as an alloying element in steel and REACH (EC 1907/2006) regulations, meeting international environmental and safety standards for industrial hardware.
