Professional Applications & Engineering Value

This heavy-duty hook hold-down bolt addresses critical engineering challenges in industrial fastening systems where secure anchoring and consistent tension are paramount. The zinc-plated steel construction provides essential corrosion protection for applications exposed to environmental elements, while the 60,000 PSI tensile strength ensures structural integrity under dynamic loads. The 55° round hook profile with 11/16" hook length offers superior engagement with anchor points, distributing stress evenly to prevent premature failure. The UNC coarse thread pattern with Class 2A fit enables rapid installation in manufacturing environments, reducing assembly time without compromising holding power. Ideal for machinery anchoring, transport securing systems, and equipment fastening where reliable hold-down capability is essential for operational safety and equipment stability.

Specification Summary & Compliance

This 1/4"-20 x 9 1/4" hook hold-down bolt features precise Class 2A thread fit with UNC coarse thread specifications (2 3/4" threaded length) and right-hand thread direction. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across industrial applications. The partially threaded design maintains dimensional accuracy while the 0.25" screw diameter and Rockwell B70 hardness guarantee consistent performance meeting industrial fastening standards.
