Professional Applications & Engineering Value

This zinc-plated steel hanger bolt delivers exceptional engineering value in industrial hanging applications where corrosion resistance and structural integrity are critical. The eye head design provides a secure attachment point for cables, chains, or ropes in construction, machinery mounting, and overhead suspension systems. With UNC coarse threading and Class 2B thread fit, it offers reliable engagement in both metal and wood substrates, preventing loosening under dynamic loads. The partial threading allows for precise depth control during installation, while the Rockwell B68 hardness ensures the bolt maintains its structural integrity under substantial weight loads. This combination of features makes it ideal for demanding environments where hanging hardware must withstand both mechanical stress and environmental exposure.

Specification Summary & Compliance

This hanger bolt features 1/4"-20 UNC coarse threading with Class 2B thread fit for standard industrial compatibility. The manufacturing adheres to precise dimensional specifications including a 1 1/2" length and 1/4" eye diameter. The product is fully RoHS 3 (2015/863/EU) compliant, meeting international environmental regulations for hazardous substance restrictions. The zinc-plated steel construction combined with Rockwell B68 hardness provides both corrosion resistance and mechanical durability for long-term performance in commercial and industrial applications.
