Professional Applications & Engineering Value
Engineered for industrial set screws applications requiring uncompromising reliability, this 5/16"-18 UNC set screw delivers exceptional performance in machinery, automotive, and manufacturing equipment. The black-oxide alloy steel material provides excellent wear resistance and reduces galling during repeated adjustments. Its headless design and cone point tip create concentrated clamping force, effectively securing pulleys, gears, and collars without protruding components. The Class 3A thread fit and coarse thread spacing ensure vibration-resistant fastening in high-stress environments, while the hex drive configuration allows for efficient torque application in confined spaces. This combination addresses common engineering challenges of component slippage, corrosion-induced failure, and installation inefficiency in heavy-duty set screws applications.
Specification Summary & Compliance
This set screw maintains Class 3A thread fit precision with UNC thread form and 5/16"-18 thread size. Manufacturing conforms to ASME B18.3 specifications where identified as ASTM F912, ensuring dimensional accuracy and performance consistency. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting current environmental and safety standards for industrial components.
