• Global compliance assurance meeting RoHS 3 and REACH regulations for safe use in regulated industries

Professional Applications & Engineering Value

This precision shoulder screw is engineered to solve critical alignment and wear challenges in industrial machinery. The 360 Brass material offers excellent corrosion resistance, making it suitable for marine, chemical, and electronic applications where steel may corrode. The 1/4" shoulder length with precise tolerances acts as a pivot or axle, ensuring accurate component positioning in assemblies like rotating shafts, gears, and linkages. The 10-32 UNF fine threads with Class 2A fit provide secure fastening in thin materials and high-vibration environments, common in automotive, aerospace, and precision instrument manufacturing. The socket head hex drive allows for compact installation in confined spaces, reducing assembly time while maintaining high clamp load. This combination of machinability, strength, and dimensional stability makes it a reliable choice for OEMs and maintenance teams requiring long-term performance.

Specification Summary & Compliance

This shoulder screw adheres to UNF thread standards with a Class 2A thread fit for consistent engagement. The shoulder features a diameter of 1/4" with a tolerance of -0.002" to 0" and a length of 1/8" with a tolerance of 0" to 0.003" for precise assembly. Manufactured from 360 Brass, it achieves Rockwell B55 hardness, 40,000 psi tensile strength, and 22,000 psi shear strength. The product is fully compliant with RoHS 3 (2015/863/EU) under exemption 6(c) for lead in copper alloy and REACH (EC 1907/2006) regulations, ensuring environmental and safety standards are met for industrial use.
