Key Features & Benefits at a Glance
- Superior corrosion resistance from 316 Stainless Steel construction, ideal for harsh chemical and marine environments
- Exceptional mechanical strength with 70,000 PSI tensile strength and Rockwell B70 hardness for heavy-duty load-bearing applications
- Optimized torque transmission through the 1 5/16" external hex head design, preventing tool slippage during installation
- Reliable coarse threading (UNC) for faster assembly and reduced cross-threading risk in industrial settings
- Precision thread fit (Class 2A) ensuring consistent engagement and vibration resistance in critical connections
- Partial threading design providing enhanced clamping force distribution across unthreaded shank sections
- Full regulatory compliance meeting ASME B18.2.1 specifications and environmental standards (RoHS 3, REACH)
Professional Applications & Engineering Value
Engineered for demanding industrial environments, these 316 stainless steel hex head screws deliver exceptional performance where corrosion resistance and mechanical integrity are paramount. The coarse UNC threading enables rapid installation in structural steel, heavy machinery, and marine equipment, while the external hex drive accommodates high-torque applications without stripping. With partial threading along the 5" length, these fasteners provide superior clamping force in assemblies requiring precise load distribution. The combination of 70,000 PSI tensile strength and Rockwell B70 hardness ensures reliable performance in vibration-intensive applications, from chemical processing equipment to offshore structures, where fastener failure is not an option.
Specification Summary & Compliance
Manufactured to ASME B18.2.1 standards with Class 2A thread fit tolerance for consistent engagement. Features 7/8"-9 UNC coarse threads with right-hand direction and minimum 2" thread length. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. All dimensions conform to inch system measurements with precise head geometry (1 5/16" width, 35/64" height) for standardized tool compatibility.
