Professional Applications & Engineering Value

This 18-8 stainless steel shoulder screw is engineered to address common challenges in machinery and equipment assembly, such as component misalignment and joint failure. The 1/2"-13 UNC coarse thread and Class 3A thread fit provide a tight, secure connection that resists vibration and loosening in dynamic applications like rotating shafts, linkages, and pivoting mechanisms. The knurled socket head with a 3/8" hex drive ensures easy, high-torque installation without cam-out, reducing assembly time and tool wear. Made from corrosion-resistant stainless steel, it excels in environments exposed to moisture, chemicals, or temperature variations, making it ideal for automotive, manufacturing, and industrial automation systems where reliability and precision are critical.

Specification Summary & Compliance

This shoulder screw features a 1/2"-13 UNC coarse thread with Class 3A fit for high precision, along with a shoulder diameter of 3/4" and tolerances within -0.004" to -0.002" for diameter and -0.002" to 0.002" for length. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for global industrial use.
