• Superior wear resistance thanks to Rockwell C25 hardness, ensuring extended service life under mechanical stress
• Optimized thread engagement with Unified Standard Class 2A fit and coarse UNC threading for faster assembly and vibration resistance
• Versatile partial threading design allowing for adjustable clamping force and secure fastening in various material thicknesses
• Robust T-head design with 2" width providing superior torque transmission and anti-rotation stability
• Environmental compliance assurance meeting both REACH and RoHS 3 standards for safe industrial use
• Right-hand thread configuration following industry standards for compatibility with common installation tools and procedures

Professional Applications & Engineering Value

This high-strength steel T-bolt delivers critical engineering solutions for general purpose industrial applications where reliability under load is paramount. The 1/2"-13 UNC coarse thread configuration combined with Class 2A thread fit ensures rapid installation while maintaining vibration resistance in machinery, structural assemblies, and equipment framing. The partially threaded design allows precise adjustment where full-length threading isn't required, while the substantial 2" tee head provides excellent anti-rotation properties and tool engagement. Manufactured from hardened steel with Rockwell C25 rating, this fastener maintains dimensional stability under repeated stress cycles, making it ideal for jigs, fixtures, and heavy-duty clamping systems where 120,000 psi tensile strength prevents catastrophic failure in critical connections.

Specification Summary & Compliance

This T-bolt features precise Unified Standard Class 2A thread fit with 1/2"-13 UNC coarse threading and partial threading over 2-1/2" length. The fastener maintains strict dimensional accuracy with 3-3/4" overall length and 0.5" screw diameter. Manufacturing complies with REACH (EC 1907/2006) regulations and RoHS 3 (2015/863/EU) directives, ensuring environmental responsibility while delivering consistent mechanical performance across industrial applications.
