Professional Applications & Engineering Value
This socket head cap screw is engineered to address critical challenges in industrial fastening, such as vibration loosening and corrosion-induced degradation. The 18-8 stainless steel material provides excellent resistance to rust and chemical exposure, making it ideal for use in machinery, automotive assemblies, and outdoor equipment. The Class 3A thread fit and coarse UNC thread design ensure rapid, secure installation with minimal risk of stripping, while the high-strength 70,000 psi tensile rating supports heavy-load applications. Its fully threaded configuration distributes stress evenly, preventing joint failure in dynamic environments. This combination of durability, precision, and regulatory compliance delivers long-term reliability for engineering projects requiring robust industrial fasteners.
Specification Summary & Compliance
This screw features a 3/8"-16 UNC coarse thread with Class 3A fit for high precision, and is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance standards. Dimensions include a 1 1/4" length, 5/8" head diameter, and 3/8" square drive, ensuring consistent performance in regulated industrial applications.
