Professional Applications & Engineering Value
Engineered for critical industrial fastening applications, these socket head cap screws deliver exceptional performance where vibration resistance and mechanical strength are paramount. The black-oxide alloy steel construction combined with Class 3A UNC coarse threads provides superior fatigue resistance in machinery, automotive assemblies, and heavy equipment. The nylon patch thread locker effectively prevents loosening under cyclic loading conditions, eliminating the need for secondary locking devices. With 170,000 psi tensile strength and temperature stability from -70° to 250°F, these fully threaded screws maintain clamping force in extreme environments while the standardized hex drive ensures consistent torque application during installation.
Specification Summary & Compliance
This 8-32 UNC thread socket head cap screw features precision Class 3A thread fit with coarse thread spacing and right-hand thread direction. Manufactured to ASME B18.3 specifications with ASTM A574 material standards, ensuring dimensional accuracy and mechanical properties. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making them suitable for global industrial applications requiring stringent material restrictions.
