Professional Applications & Engineering Value

This black-oxide steel hanger bolt solves critical installation challenges in extension spring systems and industrial assembly applications. The 360° rotating head eliminates alignment issues when mounting in confined spaces, while the wrench flats provide positive torque control during installation. The M3.5 coarse thread with 0.6 mm pitch ensures rapid assembly with reduced risk of thread damage, making it ideal for high-volume production environments. The black-oxide surface treatment creates a durable barrier against moisture and chemicals, extending service life in automotive, machinery, and equipment manufacturing applications where corrosion resistance is essential for long-term reliability.

Specification Summary & Compliance

Manufactured to precise metric thread standards with M3.5 diameter and 0.6 mm coarse pitch, this hanger bolt features 10 mm minimum thread length and 16 mm total length for consistent performance. The product maintains dimensional accuracy suitable for industrial applications and complies with RoHS 3 (2015/863/EU) with exemption 6(a) for lead as an alloying element in steel, along with full REACH (EC 1907/2006) compliance for hazardous substances.
