• High tensile strength of 60,000 psi combined with Rockwell B70 hardness for reliable performance under heavy loads
• Enhanced grip and vibration resistance with partially threaded UNC coarse threading and Class 2A fit
• Versatile 9" length with 2 3/4" threaded portion for adjustable fastening depth in various mounting applications
• Compliance with RoHS 3 and REACH regulations ensures safe, environmentally responsible use in industrial settings

Professional Applications & Engineering Value

This heavy-duty hold-down bolt is engineered to address critical challenges in industrial fastening, where vibration resistance and secure anchoring are paramount. The zinc-plated steel construction provides excellent corrosion protection, making it ideal for outdoor equipment, machinery mounts, and structural applications exposed to moisture. The 45° flat hook profile with a 1/2" length ensures maximum contact and prevents pull-out under dynamic loads, while the partially threaded UNC coarse design allows for precise tension control and reduces the risk of thread stripping. With a 60,000 psi tensile strength and Rockwell B70 hardness, it delivers reliable performance in demanding environments such as construction, transportation, and heavy machinery, where failure is not an option.

Specification Summary & Compliance

This bolt features a 1/4"-20 UNC coarse thread with Class 2A fit for standard tolerance and easy assembly. The threading is partially applied over 2 3/4", and the hook measures 1/2" in length with 5/32" thickness. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety standards for industrial use.
