Professional Applications & Engineering Value
This high-strength steel T-bolt addresses critical engineering challenges in industrial fastening systems where vibration resistance and consistent clamping force are paramount. The UNF fine threading (1/2"-20) combined with Class 2A thread fit ensures precise torque transmission and maintains joint integrity under dynamic loads. The partially threaded design with 2-1/2" thread length provides optimal stress distribution while the T-head configuration offers superior anti-rotation properties. Engineered for general purpose industrial applications, this fastener delivers reliable performance in machinery assembly, structural frameworks, and equipment manufacturing where 120,000 psi tensile strength and Rockwell C25 hardness prevent thread stripping and material failure.
Specification Summary & Compliance
Manufactured to Unified Standard Class 2A thread tolerances with 1/2"-20 UNF fine threading and right-hand thread direction. The bolt features a 2" head width with 1/2" head thickness and 3-3/4" overall length. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental and safety standards are met for industrial deployment.
