Professional Applications & Engineering Value
This high-strength steel T-bolt is engineered to solve critical fastening challenges in industrial settings. The Black Oxide finish provides a protective layer that significantly reduces oxidation and wear, making it ideal for machinery, fixtures, and structural assemblies exposed to moisture or chemicals. Its partially threaded design, combined with a 3-inch wide tee head and collar type, ensures maximum stability and load distribution, preventing loosening under vibration. The coarse UNC threading and Class 2A fit allow for quick, reliable engagement in heavy-duty T-slot applications, reducing installation errors and maintenance downtime. This bolt delivers consistent performance in clamping, jig, and mold setups, where precision and durability are paramount.
Specification Summary & Compliance
This T-bolt adheres to Unified Standard Class 2A thread fit for precise dimensional accuracy and interchangeability. It features a 5/16"-18 UNC coarse thread, partial threading with a 3/4" thread length, and a right-hand thread direction. The product is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and meets international environmental standards for quality and safety.
