Professional Applications & Engineering Value

Engineered for heavy-duty industrial applications, this hook hold-down bolt solves critical fastening challenges in machinery anchoring, transport securing, and structural restraints. The round hook profile with precise 63° angle distributes stress evenly, preventing sudden release under dynamic loads. Manufactured from Grade 5 steel with Rockwell C25 hardness, it maintains integrity in high-vibration environments where inferior fasteners fail. The partially threaded UNC coarse thread design allows for rapid installation while providing maximum thread engagement in softer materials. These industrial fasteners deliver predictable performance in rigging, construction, and manufacturing applications where safety and reliability are paramount.

Specification Summary & Compliance

This 1/2"-13 UNC bolt maintains Class 2A thread fit tolerances with 2" thread length on a 4" overall configuration. Manufactured to SAE J429 Grade 5 standards with verified 120,000 psi tensile strength. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring unrestricted use in regulated markets.
