Professional Applications & Engineering Value
This precision shoulder screw is engineered to solve critical alignment and durability challenges in demanding industrial applications. The 18-8 stainless steel construction, enhanced by a passivated finish, provides excellent resistance to corrosion and wear, extending service life in machinery, pivots, and rotating assemblies. The precisely machined 1/2" diameter shoulder with minimal tolerances ensures exact component positioning, reducing vibration and misalignment in equipment like conveyors, automotive jigs, and automation systems. The combination of 70,000 psi tensile strength and a hex socket head allows for high clamping force and easy installation in confined spaces, making it a reliable choice for engineers seeking durable, compliant fastening solutions.
Specification Summary & Compliance
This shoulder screw features a 3/8"-16 UNC thread with Class 2A fit and coarse thread spacing for reliable engagement. The shoulder diameter is 1/2" with a tolerance of -0.001" to 0", and shoulder length is 1-1/2" with a tolerance of 0" to 0.002", ensuring precise fit. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious industrial use.
