Professional Applications & Engineering Value
This alloy steel shoulder screw with black oxide finish addresses critical alignment and corrosion challenges in precision assemblies. The 1-1/4" shoulder length provides exact spacing between components in machinery, while the 8-32 UNC thread with Class 2A fit ensures secure fastening in vibrating environments. The hex socket drive enables high-torque installation in confined spaces, making it ideal for industrial automation equipment, precision instruments, and rotating assemblies where shoulder diameter tolerance controls critical clearances. The combination of 140,000 psi tensile strength and corrosion-resistant finish delivers long-term reliability in manufacturing and mechanical systems.
Specification Summary & Compliance
Manufactured to Class 2A thread fit standards with UNC coarse thread spacing and precise shoulder diameter tolerance of -0.001" to 0". The component meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements, ensuring environmental regulation adherence for industrial applications requiring controlled dimensional accuracy and material consistency.
