Key Features & Benefits at a Glance
- Exceptional durability with 70,000 psi tensile strength and Rockwell C45 hardness for reliable performance in demanding applications
- Superior corrosion resistance through black oxide finish that protects against rust and extends service life
- Precise thread engagement with Unified Standard Class 2A fit ensuring consistent fastening performance
- Optimized load distribution from the 3 1/2" wide tee head design that prevents pull-through in soft materials
- Easy installation and adjustment with partially threaded 3/4"-10 UNC coarse thread pattern and right-hand direction
- Enhanced stability provided by the 1/2" collar length that maintains proper alignment during assembly
- Regulatory compliance assurance meeting both REACH and RoHS 3 environmental standards for industrial use
Professional Applications & Engineering Value
This high-strength steel T-bolt delivers exceptional engineering value across industrial applications where vibration resistance and structural integrity are critical. The black oxide finish provides essential corrosion protection in manufacturing environments, while the 3/4"-10 UNC coarse threading ensures rapid installation and reliable performance in woodworking machinery, fixture clamping systems, and structural steel connections. The partially threaded design with 3/4" thread length concentrates strength where needed most, preventing thread stripping in soft materials. The substantial 3 1/2" tee head distributes clamping force effectively, making it ideal for T-slots in machine beds, welding fixtures, and heavy-duty jigs where repeated adjustments are necessary without compromising joint security.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Unified Standard Class 2A thread fit and 3/4"-10 UNC coarse thread specifications. The fastener maintains 0.75" screw diameter tolerance throughout the 6 7/8" length with 1/2" collar length for consistent performance. Fully compliant with REACH (EC 1907/2006) regulations and RoHS 3 (2015/863/EU) directives, ensuring environmental responsibility while delivering 70,000 psi tensile strength and Rockwell C45 hardness for industrial durability requirements.
