Professional Applications & Engineering Value

This precision shoulder screw is engineered to address common industrial challenges such as misalignment, vibration loosening, and corrosion in machinery. The 18-8 Stainless Steel material, combined with a passivated finish, provides excellent resistance to rust and chemicals, making it suitable for automotive, aerospace, and precision equipment applications. The 1" shoulder with precise tolerances acts as a pivot or spacer, reducing friction and wear in rotating assemblies. Its 10-32 UNF fine thread ensures tight, secure fits in high-stress environments, while the dual-drive design allows for easy installation in confined spaces. By meeting MS51575-24 specifications, it delivers consistent performance for critical engineering tasks, enhancing reliability and reducing maintenance costs.

Specification Summary & Compliance

This shoulder screw adheres to Class 2A thread fit for precise dimensional accuracy, with a shoulder diameter of 1/4" (tolerance: -0.001" to 0") and shoulder length of 1" (tolerance: 0" to 0.002").
