Professional Applications & Engineering Value

This 316 stainless steel socket head cap screw is engineered to address critical challenges in industrial settings, such as exposure to corrosive chemicals, moisture, and high-stress conditions. The passivated finish enhances the innate corrosion resistance of 316 stainless steel, making it ideal for marine, chemical processing, and food industry applications where sanitation and durability are paramount. Its Class 3A thread fit and coarse UNC thread provide excellent engagement in soft materials or where vibration loosening is a concern, while the partially threaded design concentrates clamping force for secure joints. The hex socket drive allows for high-torque installation in confined spaces, reducing assembly time and improving reliability in machinery, automotive, and structural assemblies.

Specification Summary & Compliance

This socket head cap screw adheres to precise dimensional standards, including a Class 3A thread fit for tight tolerances and a 1/2"-13 UNC coarse thread with a minimum thread length of 1 1/2". Manufactured in accordance with inch system measurements, it ensures compatibility with North American and international specifications. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted hazardous substances and supporting environmental and safety standards in industrial supply chains.
