• High tensile strength of 70,000 psi ensures reliable performance under heavy mechanical stress
• Precise Class 2A thread fit guarantees smooth assembly and consistent fastening quality
• Full threading along the 5/8" length allows for maximum grip and adjustability in various material thicknesses
• Industry-standard compliance with ASME B18.5, RoHS 3, and REACH ensures safety and regulatory acceptance

Professional Applications & Engineering Value

This 5/16"-18 UNC carriage bolt delivers exceptional engineering value through its 18-8 Stainless Steel composition, providing excellent corrosion resistance for demanding industrial environments. The fully threaded design with coarse UNC threading ensures rapid installation and reliable holding power in wood, metal, and composite materials. The integrated square neck mechanically locks into pre-drilled holes, eliminating rotation during torque application - a critical feature for assembly line efficiency and structural integrity. With 70,000 psi tensile strength and Rockwell B55 hardness, this fastener maintains performance under vibration and load stress, making it ideal for construction, transportation equipment, and machinery applications where failure is not an option.

Specification Summary & Compliance
