Key Features & Benefits at a Glance

  • Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments
  • Exceptional load-bearing capacity with 70,000 psi tensile strength for heavy-duty applications
  • Secure anti-rotation locking provided by the square neck design, preventing bolt spin during installation
  • Wide bearing surface from the rounded carriage head for enhanced load distribution and material protection
  • Reliable coarse threading (UNC 10-24) for faster assembly and reduced cross-threading risk
  • Precision manufacturing with Class 2A thread fit ensuring consistent performance and compatibility
  • Full regulatory compliance meeting ASME B18.5 standards, RoHS 3, and REACH environmental requirements

Professional Applications & Engineering Value

This 10-24 UNC carriage bolt delivers critical engineering solutions where vibration resistance and structural integrity are paramount. The 18-8 stainless steel composition provides excellent corrosion resistance for outdoor equipment, marine applications, and food processing machinery. The fully threaded coarse spacing design enables rapid installation in wood-to-metal and structural steel connections, while the square neck securely locks into materials to prevent rotational movement under dynamic loads. With Rockwell B55 hardness and 70,000 psi tensile strength, this fastener maintains clamping force in high-stress industrial assemblies, making it ideal for construction, transportation equipment, and heavy machinery applications requiring durable, compliant fastening solutions.

Specification Summary & Compliance

Manufactured to precise Class 2A thread fit tolerances with UNC 10-24 coarse threading and right-hand thread direction. Complies with ASME B18.5 dimensional standards and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental compliance requirements. Features include 0.19" screw diameter, 3/4" length, and square neck measuring 0.13" length by 0.2" width for secure anti-rotation performance.
