  • Regulatory compliance assurance meeting both RoHS 3 and REACH standards for safe industrial use

Professional Applications & Engineering Value

This heavy-duty steel T-bolt delivers critical engineering solutions where standard fasteners fail. The 3/8"-16 UNC coarse thread configuration provides excellent resistance to vibration loosening while maintaining quick assembly/disassembly capabilities. Engineered with Rockwell C25 hardness and 120,000 psi tensile strength, it withstands extreme mechanical stresses in machinery, structural frameworks, and industrial equipment. The zinc plated finish creates a protective barrier against corrosion in humid or outdoor environments. The T-head design with 1 3/4" width offers superior torque transmission and prevents spinning in channel nuts or T-slots, making it ideal for manufacturing fixtures, automotive assemblies, and construction applications where reliability is paramount.

Specification Summary & Compliance

This T-bolt features Unified Standard Class 2A thread fit with 3/8"-16 UNC coarse threads and right-hand direction. Manufacturing specifications include 2 15/16" total length with 1 1/2" threaded portion, 1 3/4" head width, and 3/8" head thickness. The product fully complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial procurement.
