Professional Applications & Engineering Value

This 5/8"-11 UNC steel hold-down bolt delivers critical engineering value in applications where superior tensile strength and reliable anchoring are paramount. The round hook profile with precise 63° angle distributes stress evenly, preventing point loading failures in machinery securing, structural fastening, and equipment mounting scenarios. The partially threaded design allows for optimal grip length adjustment while the coarse UNC threading provides excellent resistance to vibration loosening. Manufactured from Grade 5 steel with Rockwell C25 hardness, this bolt maintains integrity under repeated loading cycles, making it ideal for industrial environments where hold-down applications demand both immediate strength and long-term reliability without compromising on regulatory compliance.

Specification Summary & Compliance

This heavy-duty fastener features precise Class 2A thread fit with UNC coarse thread spacing (5/8"-11) and partial threading over 3" length. Manufacturing adheres to SAE J429 Grade 5 specifications, ensuring dimensional accuracy and mechanical properties. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, providing assurance for use in regulated industrial applications requiring documented material compliance.
