Professional Applications & Engineering Value

This nickel alloy shoulder screw addresses critical challenges in precision machinery and heavy-duty equipment, where misalignment and material failure cause costly downtime. The 3/4" shoulder length provides a stable pivot or bearing surface, minimizing bushings wear in rotating assemblies. Its Class 3A UNC coarse threads ensure rapid, secure fastening in high-vibration environments like automotive jigs or conveyor systems. The hex drive socket head with knurling allows for high-torque installation without slippage, while the nickel alloy composition resists oxidation and chemical exposure in marine or chemical processing applications. Engineered for 70,000 psi tensile strength, it reliably supports dynamic loads in robotics, aerospace components, and industrial molds, reducing maintenance intervals and improving operational safety.

Specification Summary & Compliance

This shoulder screw maintains Class 3A thread fit per UNC standards with a shoulder diameter tolerance of -0.004" to -0.002" and length tolerance of -0.005" to 0.005" for precision assembly. Manufacturing adheres to industry norms for coarse threads (8-32 UNC) and right-hand thread direction. The product is fully RoHS 3 (2015/863/EU) compliant under exemption 6(c) and REACH (EC 1907/2006) compliant per the latest SVHC list, ensuring regulatory acceptance in international markets.
