• Regulatory compliance assurance meeting ASME B18.2.1 specifications and environmental standards
• Dimensional precision with 3" length and controlled thread geometry for consistent assembly performance

Professional Applications & Engineering Value

This 316 stainless steel hex head screw delivers critical performance advantages in demanding industrial settings where corrosion resistance and structural integrity are paramount. The UNC coarse thread configuration with Class 2A fit ensures rapid installation and vibration resistance in heavy machinery, chemical processing equipment, and marine applications. The partially threaded design concentrates clamping force precisely where needed, while the external hex drive accommodates high-torque installation. Engineered to withstand extreme environments, this ASME B18.2.1 compliant fastener provides long-term reliability in infrastructure, manufacturing, and offshore applications where failure is not an option.

Specification Summary & Compliance

Manufactured to exacting ASME B18.2.1 standards with Class 2A thread fit tolerances ensuring consistent mating with corresponding nuts. The 7/16"-14 UNC coarse thread maintains dimensional accuracy across the 3" length with partial threading extending 1-1/8" minimum. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations guarantees safe use across regulated industries. Mechanical properties certified to 70,000 psi tensile strength and Rockwell B70 hardness for verified performance documentation.
