Professional Applications & Engineering Value

This precision shoulder screw is engineered to address common industrial challenges such as misalignment and component wear in high-stress assemblies. The 18-8 stainless steel construction, combined with a passivated finish, resists corrosion and extends service life in moist or chemical-exposed settings. The 10-32 UNF fine thread and Class 2A fit deliver secure, vibration-resistant fastening, critical for maintaining accuracy in machinery like CNC equipment, automotive fixtures, and electronic enclosures. The low socket head design minimizes space requirements while the precisely machined shoulder ensures smooth bearing surfaces, reducing friction and preventing part failure. Ideal for applications demanding exact tolerances and robust performance, this screw supports efficient production and reduced maintenance costs.

Specification Summary & Compliance

This shoulder screw adheres to inch system measurements with a 10-32 UNF thread and Class 2A thread fit for precise engagement. Shoulder dimensions include a diameter of 1/4" (tolerance: -0.001" to 0") and length of 5/8" (tolerance: 0" to 0.002"), ensuring accurate alignment. It conforms to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and material compliance for industrial use.
