Key Features & Benefits at a Glance
- Exceptional durability with Rockwell C45 hardness steel construction that withstands heavy-duty industrial applications
- Superior corrosion resistance through black oxide finish that protects against rust and extends service life
- Optimized load distribution with 3½" head width and collar design that prevents pull-through in demanding applications
- Reliable fastening performance with 70,000 psi tensile strength ensuring secure connections under high stress conditions
- Easy installation and adjustment through partially threaded design with ¾" thread length for precise positioning control
- Consistent thread engagement with Unified Standard Class 2A fit and coarse UNC threading that resists loosening
- Global compliance assurance meeting both REACH and RoHS 3 environmental standards for international industrial use
Professional Applications & Engineering Value
This high-strength steel T-bolt with black oxide finish addresses critical engineering challenges in industrial clamping systems, machinery assembly, and structural frameworks. The 3/8"-16 UNC coarse threading with Class 2A fit ensures rapid installation while maintaining vibration resistance in high-stress environments. The partially threaded design combined with the substantial 3½" head width provides optimal load distribution, preventing material deformation in soft metals or composite materials. Engineers value the 70,000 psi tensile strength and Rockwell C45 hardness for applications requiring repeated adjustments without thread wear, making it ideal for fixture manufacturing, automotive jigs, and industrial equipment where reliability and corrosion resistance are paramount.
Specification Summary & Compliance
This T-bolt maintains precise Unified Standard Class 2A thread fit with 3/8"-16 UNC coarse threading and right-hand thread direction. Manufacturing complies with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental standards. The fastener features a collar-type T-bolt design with 5" overall length, ½" collar length, and partial threading covering ¾" of the shank. The steel construction achieves consistent Rockwell C45 hardness and 70,000 psi tensile strength, ensuring reliable performance in industrial fastening applications.
