Professional Applications & Engineering Value
This 5/8"-11 UNC shoulder screw is precision-engineered from 18-8 stainless steel to address critical industrial demands for durability and alignment. The coarse UNC thread with Class 2A fit ensures rapid assembly and secure fastening in high-vibration settings like machinery, automotive assemblies, and conveyor systems. The knurled hex socket head provides superior anti-slip performance, allowing high torque application without stripping. Its shoulder diameter and length are manufactured to tight tolerances, offering exact pivot points or spacers in rotating mechanisms, reducing wear and misalignment. Combined with RoHS and REACH compliance, it supports sustainable manufacturing while delivering reliable performance in demanding environments.
Specification Summary & Compliance
This shoulder screw adheres to UNC coarse thread standards with Class 2A thread fit for consistent engagement. Shoulder diameter tolerance is -0.004" to -0.002", and shoulder length tolerance is -0.005" to 0.005" for precision alignment. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental safety and regulatory adherence for industrial use.
