Professional Applications & Engineering Value
This 5/16"-18 UNC Hex Head Screw in 316 Stainless Steel is engineered to solve critical challenges in industrial settings where corrosion and mechanical stress are prevalent. The coarse thread design ensures secure fastening in soft or composite materials, reducing the risk of stripping. With a 3-1/2" length and partial threading, it offers versatile clamping for structural assemblies, machinery, and marine equipment. The external hex drive facilitates high-torque installation, making it ideal for maintenance and production lines. Its 70,000 PSI tensile strength and Rockwell B70 hardness provide reliable performance under heavy loads, while the 316 stainless steel composition resists pitting and oxidation in saline or chemical environments, extending service life and reducing replacement costs.
Specification Summary & Compliance
This screw features Class 2A thread fit per UNC standards, ensuring dimensional accuracy and compatibility. It is manufactured in compliance with ASME B18.2.1 specifications for hex head screws. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting stringent environmental and safety regulations for industrial use.
