Professional Applications & Engineering Value

This 6-32 UNC shoulder screw is engineered to address critical alignment and durability challenges in precision industrial applications. The 18-8 stainless steel material, combined with a passivated finish, provides superior resistance to rust and chemical exposure, making it ideal for machinery, automotive components, and electronic enclosures operating in corrosive conditions. The 1/2" shoulder length with tight tolerances ensures exact positioning of moving parts, reducing friction and preventing misalignment in assemblies like bearings, gears, and pivots. Its coarse thread and Class 2A fit facilitate efficient installation, while the low socket head profile and hex drive allow for secure fastening in space-constrained designs, enhancing overall engineering reliability and maintenance efficiency.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 2A thread fit for consistent dimensional accuracy. The shoulder diameter is precisely controlled at 5/32" with a tolerance of -0.001" to 0", and the shoulder length is 1/2" with a tolerance of 0" to 0.002", ensuring reliable performance in high-precision assemblies. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming its suitability for environmentally regulated and industrial applications requiring dependable fastening solutions.
