Professional Applications & Engineering Value
Engineered for precision applications where reliable fastening and space constraints are critical, these low profile socket head cap screws solve common engineering challenges. The black-oxide alloy steel construction provides excellent corrosion resistance while maintaining the high tensile strength required for structural components, machinery assembly, and automotive applications. The 5/16"-18 UNC coarse threads ensure quick installation and superior vibration resistance in high-stress environments. With their reduced head profile, these screws are particularly valuable in aerospace, robotics, and precision equipment where clearance is limited but maximum clamping force is essential for operational safety and longevity.
Specification Summary & Compliance
This socket head cap screw features precision Class 3A thread fit with 5/16"-18 UNC coarse threads and fully threaded 3/4" length. Manufactured to ASTM A574 specifications with 140,000 psi tensile strength and Rockwell C39 hardness. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets.
