Professional Applications & Engineering Value

This 10-24 UNC shoulder screw is engineered to solve critical alignment and durability challenges in precision assemblies. The 18-8 stainless steel material, enhanced by a passivated finish, provides excellent resistance to oxidation and chemical exposure, making it ideal for machinery, automotive, and electronic applications where corrosion is a concern. The precisely machined 1/4" shoulder diameter acts as a pivot or bearing surface, ensuring components like gears, linkages, and rollers are accurately positioned without the need for additional bushings. This design reduces assembly complexity, minimizes wear, and maintains operational integrity under dynamic loads, supported by its 70,000 psi tensile strength. The hex socket drive allows for compact installation in tight spaces, enhancing usability in automated or manual production lines.

Specification Summary & Compliance
