Professional Applications & Engineering Value

This 8-32 UNC shoulder screw is engineered to address common industrial challenges such as misalignment, component wear, and corrosion. The 18-8 Stainless Steel construction, enhanced by a passivated finish, provides superior resistance to rust and chemicals, making it ideal for precision machinery, automotive assemblies, and electronic enclosures. The 1-1/4" shoulder length with minimal tolerance ensures exact positioning of moving parts, reducing friction and extending equipment lifespan. Its hex socket head allows for efficient torque application in confined spaces, while the coarse UNC thread and Class 2A fit guarantee secure fastening even under vibration. By meeting MS51576-15 specifications, this screw delivers consistent performance in high-stress environments, supporting reliable industrial assembly and maintenance operations.

Specification Summary & Compliance

This shoulder screw features a Class 2A thread fit with UNC coarse threads for standard compatibility and ease of assembly. The shoulder diameter and length are manufactured to precise tolerances (e.g., shoulder diameter: -0.001" to 0", shoulder length: 0" to +0.002") to ensure accurate fit. It complies with MS51576-15 specifications and is verified to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, adhering to environmental and safety regulations for industrial use.
