Professional Applications & Engineering Value
This 3/8"-16 x 2 1/2" partially threaded socket head cap screw delivers exceptional engineering value in industrial settings where corrosion resistance and high tensile strength are critical. The 18-8 Stainless Steel material, enhanced by a passivated finish, combats rust and chemical exposure in machinery, marine, and outdoor equipment. Its Class 3A thread fit and UNRC coarse thread provide superior clamping force and reduce the risk of loosening under vibration, common in automotive and aerospace assemblies. The partially threaded configuration offers a smooth shank for precise alignment and shear strength, while the hex socket drive ensures secure fastening in tight spaces, minimizing installation time and improving maintenance efficiency.
Specification Summary & Compliance
This socket head cap screw features a 3/8"-16 UNRC coarse thread with Class 3A fit for high precision, a minimum thread length of 1-1/2", and overall length of 2-1/2". It conforms to specifications including MS16995-87, NAS1352C6-40, and NASM16995, ensuring adherence to rigorous industrial standards. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting environmental and safety regulations for global supply chains.
