Professional Applications & Engineering Value
This 5/16"-18 UNC hex head screw in 316 stainless steel delivers exceptional value in corrosive environments where fastener failure is not an option. The combination of 70,000 psi tensile strength and Class 2A thread fit ensures reliable performance in structural applications, marine equipment, chemical processing, and food processing machinery. The coarse thread design provides superior holding power in softer materials while resisting vibration-induced loosening. With full threading along the entire 1" length, this fastener distributes clamping force evenly, preventing stress concentration points that can lead to material failure. The external hex drive accommodates high torque requirements, making it ideal for maintenance-critical applications where disassembly may be necessary.
Specification Summary & Compliance
This hex head screw features precise Class 2A thread fit per UNC standards with 5/16"-18 coarse threading and right-hand orientation. Manufactured to ASME B18.2.1 specifications with Rockwell B70 hardness and dimensional accuracy. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors.
