Professional Applications & Engineering Value

This 1/2"-13 UNC shoulder screw is engineered to address critical alignment and pivot point requirements in industrial machinery, automation systems, and precision equipment. The 18-8 stainless steel material provides excellent resistance to rust and corrosion, making it suitable for demanding environments like food processing, marine applications, and outdoor equipment. The Class 3A thread fit and coarse UNC thread ensure secure fastening even under high vibration, reducing the risk of loosening. The precisely ground shoulder diameter acts as a pivot or bearing surface, eliminating the need for additional bushings and simplifying assembly. With a knurled socket head and 5/16" hex drive, installation is straightforward, minimizing assembly time and improving workplace efficiency. This screw is a reliable choice for engineers seeking durability, precision, and compliance in their heavy-duty designs.

Specification Summary & Compliance

This shoulder screw adheres to UNC coarse thread standards with a Class 3A thread fit for high precision. The shoulder features a diameter of 5/8" with tight tolerances (e.g., diameter: -0.004" to -0.002") to ensure accurate alignment. Manufactured from 18-8 stainless steel with a hardness of Rockwell B55, it meets mechanical properties including 70,000 psi tensile strength. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing it is free from hazardous substances and suitable for global industrial use.
