Professional Applications & Engineering Value
This 10-32 UNF shoulder screw is engineered to address critical alignment and high-load challenges in precision machinery. The alloy steel construction, combined with Class 3A thread fit and black oxide finish, provides exceptional resistance to loosening under vibration, making it ideal for rotating assemblies, pivots, and guide mechanisms. The knurled socket head ensures secure tool engagement during installation, reducing slippage in confined spaces. With a 140,000 psi tensile strength and controlled shoulder dimensions, it supports exact component positioning in automotive, aerospace, and industrial equipment, minimizing wear and maintenance downtime.
Specification Summary & Compliance
This shoulder screw adheres to UNF fine thread standards with Class 3A precision tolerance for reliable thread engagement. Shoulder diameter tolerance is -0.004" to -0.002", and shoulder length tolerance is -0.005" to 0.005" for consistent fit. Manufacturing complies with RoHS 3 (2015/863/EU) with exemption 6(a) and REACH (EC 1907/2006) standards, ensuring environmental and safety regulations are met for industrial use.
