Professional Applications & Engineering Value
This 316 stainless steel socket head cap screw is engineered to address critical challenges in industrial settings where corrosion, high stress, and precise fit are paramount. The 5/16"-18 UNC coarse thread with Class 3A fit ensures minimal backlash and superior resistance to loosening under dynamic loads, making it ideal for machinery, marine equipment, and chemical processing applications. The partially threaded rod design concentrates threads where needed, reducing weight and preventing galling. Combined with a passivated finish and hex drive, it offers easy installation in confined spaces while maintaining long-term reliability in aggressive environments.
Specification Summary & Compliance
This fastener adheres to inch system dimensions with a Class 3A thread fit for high precision. It features UNC coarse threads (5/16"-18), a right-hand thread direction, and a partially threaded shank with a minimum thread length of 1-1/8". The screw complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets stringent environmental and safety standards for industrial use.
