Professional Applications & Engineering Value

This 8-32 UNC shoulder screw is engineered to address common industrial challenges such as misalignment and component wear in rotating assemblies. The 360 brass material provides excellent machinability and corrosion resistance, making it suitable for electrical enclosures, marine hardware, and precision instruments where non-magnetic properties are essential. The hex socket drive allows for high-torque installation in confined spaces, while the coarse UNC threads ensure rapid assembly and reduced cross-threading risks. With a 3/16" shoulder diameter and 1" shoulder length, it serves as an ideal axle or guide in linkages, bearings, and optical devices, maintaining dimensional stability under operational stresses. Its Class 2A thread fit guarantees consistent performance in automated production lines, minimizing downtime and rework.

Specification Summary & Compliance

This shoulder screw adheres to UNC coarse thread standards with a Class 2A thread fit for precise engagement. The shoulder diameter tolerance is controlled within -0.002" to 0", and the shoulder length tolerance from 0" to 0.003" to ensure exact alignment. Manufactured from 360 brass with a hardness of Rockwell B55, it meets mechanical requirements including 40,000 psi tensile strength and 22,000 psi minimum shear strength. The product is fully compliant with RoHS 3 (2015/863/EU) under exemption 6(c) for lead in copper alloys and REACH (EC 1907/2006) regulations, confirming its suitability for global industrial applications.
