Professional Applications & Engineering Value

This nickel alloy shoulder screw delivers exceptional performance in precision assemblies where corrosion resistance and dimensional stability are critical. The 8-32 UNC coarse thread with Class 3A fit ensures secure fastening in metal components and plastics, while the precisely machined shoulder provides accurate alignment for rotating parts in machinery, automotive, and aerospace applications. The hex socket drive combined with knurled head texture prevents cam-out during high-torque installation, maintaining fastener integrity. With 70,000 psi tensile strength and excellent shear resistance, these shoulder screws withstand vibrational loads and thermal cycling in demanding industrial environments, reducing maintenance frequency and downtime.

Specification Summary & Compliance

This precision shoulder screw features 8-32 UNC coarse threads with Class 3A thread fit for tight tolerance applications. The shoulder maintains critical dimensions with diameter tolerance of -0.004" to -0.002" and length tolerance of -0.005" to 0.005". Manufactured from high-strength nickel alloy with Rockwell B60 hardness, the fastener delivers 70,000 psi tensile strength and 35,000 psi minimum shear strength. Compliant with RoHS 3 (2015/863/EU) with exemption 6(c) and REACH (EC 1907/2006) standards, ensuring environmental regulatory adherence for industrial applications.
