Professional Applications & Engineering Value

This 3/8"-16 UNC hex head screw in 316 stainless steel addresses critical industrial challenges where corrosion resistance and structural integrity are paramount. The fully threaded coarse spacing design provides superior vibration resistance and faster assembly in heavy machinery, marine equipment, and chemical processing systems. Engineers specify this fastener for its ability to maintain 70,000 PSI tensile strength in corrosive environments, eliminating premature failure concerns. The external hex drive accommodates high-torque applications while the Class 2A thread fit ensures consistent performance across repeated disassembly cycles. These characteristics make it particularly valuable for structural connections, pressure vessels, and offshore applications where reliability cannot be compromised.

Specification Summary & Compliance

Manufactured to precise Class 2A thread tolerances with UNC coarse thread spacing per ASME B18.2.1 specifications. The 2-3/4" length and 3/8"-16 thread size maintain dimensional accuracy for consistent fit. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material traceability. The 316 stainless steel composition combined with Rockwell B70 hardness verification guarantees mechanical performance meets industrial standards for demanding applications.
