Professional Applications & Engineering Value
These 18-8 Stainless Steel Hex Head Screws deliver outstanding performance in demanding industrial applications where corrosion resistance and mechanical strength are critical. The UNC coarse thread design prevents cross-threading and enables faster installation in production lines, while the external hex drive accommodates high torque requirements without stripping. With 80,000 psi tensile strength and Rockwell B70 hardness, these screws maintain integrity under dynamic loads, making them ideal for machinery assembly, structural frameworks, and equipment exposed to moisture or chemicals. The fully threaded 1/4"-20 x 3/4" configuration ensures consistent clamping force, solving common issues of loosening in vibrating environments.
Specification Summary & Compliance
This hex head screw features precise Class 2A thread fit and UNC coarse threading with right-hand direction, manufactured to ASME B18.2.1 standards for dimensional accuracy. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions adherence. The inch system measurements include a 1/4"-20 thread size and 3/4" length, providing reliable performance in accordance with industrial specifications.
