Professional Applications & Engineering Value
This 18-8 Stainless Steel Socket Head Cap Screw is engineered to address critical challenges in industrial settings, such as vibration loosening and corrosion-induced failure. Its UNC coarse thread and Class 3A thread fit provide superior holding power in metals and plastics, reducing maintenance needs in machinery, automotive, and heavy equipment. The partially threaded design ensures precise clamping without over-compression, while the hex drive allows for high-torque applications in confined spaces. Made from corrosion-resistant stainless steel, it excels in moist or chemical-exposed environments, extending service life and minimizing downtime. Ideal for high-stress assemblies, this fastener delivers consistent performance where reliability is non-negotiable.
Specification Summary & Compliance
This screw features a 3/8"-16 UNC coarse thread with Class 3A thread fit for high precision, a length of 5", and a partially threaded rod. It meets ASME B18.3 specifications for dimensional accuracy and performance. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and safe for various industrial applications.
