Professional Applications & Engineering Value

This 5-40 UNC shoulder screw delivers exceptional engineering value in precision assemblies where alignment and strength are critical. Manufactured from 18-8 Stainless Steel, it resists corrosion in humid or chemically aggressive settings, reducing maintenance and replacement costs. The Class 3A thread fit and coarse UNC threading provide excellent vibration resistance, making it suitable for rotating machinery, automation systems, and fixture designs. The knurled socket head with a 3/32" hex drive ensures tool grip during installation, preventing cam-out and reducing assembly errors. Its 3/16" shoulder length acts as a precise spacer or pivot, eliminating the need for additional components and simplifying designs in robotics, aerospace, and electronic enclosures.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 3A thread fit for high precision. Dimensions include a shoulder diameter of 5/32" (tolerance: -0.004" to -0.002") and shoulder length of 3/16" (tolerance: -0.005" to 0.005"). It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material transparency for global industrial applications.
