Key Features & Benefits at a Glance

  • Superior corrosion resistance thanks to 18-8 stainless steel construction, ideal for harsh industrial environments
  • Exceptional tensile strength of 70,000 psi ensures reliable performance in heavy-duty applications
  • Secure anti-rotation locking provided by the square neck design, preventing bolt spin during installation
  • Optimized thread engagement with Class 2A fit and UNC coarse threads for faster assembly and vibration resistance
  • Enhanced durability with Rockwell B55 hardness, maintaining structural integrity under repeated stress
  • Versatile partial threading allows for both clamping and adjustment flexibility in various mounting scenarios
  • Wide rounded head profile distributes load evenly and provides a finished appearance while reducing surface damage

Professional Applications & Engineering Value

These 3/4"-10 UNC carriage bolts deliver critical engineering solutions where vibration resistance and corrosion protection are paramount. The 18-8 stainless steel composition combined with the square neck design addresses common industrial challenges of fastener loosening and material degradation in demanding environments. The partially threaded configuration with UNC coarse threads enables efficient installation in structural steel, heavy machinery, and construction applications where rapid assembly and disassembly are required. The wide rounded head provides superior bearing surface distribution, making these carriage bolts ideal for wood-to-metal connections, trailer manufacturing, and agricultural equipment where both strength and aesthetics matter.

Specification Summary & Compliance

Manufactured to precise Class 2A thread fit tolerances with UNC coarse threading (3/4"-10) and right-hand thread direction. These 6" carriage bolts meet ASME B18.5 dimensional standards and are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The 18-8 stainless steel construction ensures consistent performance with 70,000 psi tensile strength and Rockwell B55 hardness specifications maintained throughout production.
