S-92356A633 3/8"-16 x 2 1/4" ASME B18.5 Carriage Bolts

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments
• Enhanced anti-rotation security through the square neck design, preventing bolt spinning during installation
• High tensile strength of 70,000 psi ensures reliable performance under heavy loads
• Precision Class 2A thread fit with UNC coarse spacing for quick assembly and vibration resistance
• Wide rounded head profile distributes clamping force evenly and provides a finished appearance
• Full threading along the 2-1/4" length offers maximum flexibility in nut placement
• Compliance with ASME B18.5 standards guarantees dimensional accuracy and interchangeability

Professional Applications & Engineering Value

This 3/8"-16 UNC carriage bolt is engineered to solve critical fastening challenges in demanding applications. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, making it suitable for outdoor equipment, marine hardware, and food processing machinery where moisture exposure is common. The square neck securely locks into materials, eliminating rotation during tightening—a common issue in wood-to-metal connections and structural assemblies. With its fully threaded right-hand design and coarse UNC thread spacing, it ensures rapid installation and reliable performance in high-vibration environments like agricultural machinery, trailer construction, and industrial framing systems.

Specification Summary & Compliance

This carriage bolt features a Class 2A thread fit with UNC coarse threading (3/8"-16) and complies with ASME B18.5 dimensional standards. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in industrial and consumer applications. The bolt maintains a tensile strength of 70,000 psi and Rockwell B55 hardness for consistent mechanical performance.
