S-93180A120 10-24 x 1" ASME B18.5 Carriage Bolts

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh environments and outdoor applications
• Enhanced anti-rotation performance due to the square neck design that securely locks into materials during installation
• High tensile strength of 70,000 psi ensures reliable load-bearing capacity for demanding industrial applications
• Excellent thread engagement with Class 2A thread fit and coarse UNC threading for faster assembly and reduced cross-threading risk
• Wide rounded head profile provides larger bearing surface for improved load distribution and reduced surface damage
• Full threading along the 1" length offers versatile fastening depth and secure grip in various material thicknesses
• Compliance with industry standards including ASME B18.5, RoHS 3, and REACH for quality assurance and environmental safety

Professional Applications & Engineering Value

This 316 stainless steel carriage bolt delivers exceptional engineering value in corrosive and high-stress environments. The combination of marine-grade 316 stainless steel and Rockwell B55 hardness provides outstanding resistance to chemicals, saltwater, and extreme weather conditions, making it ideal for marine equipment, chemical processing plants, and outdoor structures. The square neck design prevents rotation during tightening, eliminating the need for secondary locking mechanisms and reducing installation time. The 10-24 UNC coarse thread ensures quick assembly in wood, metal, and composite materials, while the fully threaded 1" length accommodates various material thicknesses. These features collectively address common industrial challenges including vibration loosening, material degradation, and installation efficiency in heavy-duty fastening applications.
