Professional Applications & Engineering Value
Engineered for demanding industrial applications, these socket head cap screws deliver exceptional performance where vibration resistance and corrosion protection are critical. The 18-8 stainless steel construction provides excellent durability in corrosive environments, while the nylon patch thread locker prevents loosening under dynamic loads and thermal cycling from -70° to 250°F. The Class 3A thread fit with UNC coarse threads ensures precise engagement and reliable fastening in machinery, equipment assembly, and structural applications. The combination of 70,000 psi tensile strength and fully threaded design makes these fasteners ideal for high-stress applications requiring consistent clamping force and vibration resistance throughout the entire engagement length.
Specification Summary & Compliance
This 8-32 UNC thread socket head cap screw features Class 3A thread fit precision and coarse thread spacing for optimal performance. Manufactured to ASME B18.3 specifications with complete compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards. The fastener maintains dimensional accuracy with 1/4" length, 0.27" head diameter, and standard socket head profile for consistent performance across industrial applications.
