Professional Applications & Engineering Value

This 316 stainless steel shoulder screw is engineered to address critical challenges in precision assemblies, such as maintaining alignment in rotating machinery and securing components in corrosive settings. The UNC coarse thread and Class 3A fit provide a robust, vibration-resistant fastening solution that minimizes loosening under dynamic loads. Its knurled socket head with a hex drive ensures efficient torque application, reducing installation time and tool wear. Commonly used in industrial equipment, automotive subsystems, and electronic enclosures, the screw’s high tensile strength and corrosion resistance deliver long-term reliability, lowering maintenance costs and downtime.

Specification Summary & Compliance

The screw adheres to UNC thread standards with a Class 3A thread fit for precise engagement. Shoulder dimensions include a diameter of 7/32" (tolerance: -0.004" to -0.002") and length of 1" (tolerance: -0.005" to 0.005"), ensuring consistent alignment. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the use of restricted substance-free materials in manufacturing.
