Professional Applications & Engineering Value
This shoulder screw delivers exceptional engineering value in precision assembly applications where exact component positioning is critical. The 2 1/8" shoulder length provides extended bearing surface for rotating parts, pivots, and linkages, eliminating the need for additional spacers or bushings. Manufactured from 18-8 Stainless Steel, it offers excellent corrosion resistance in demanding environments including manufacturing equipment, automotive assemblies, and industrial machinery. The 1/2"-13 UNC coarse thread with Class 3A fit ensures rapid installation and reliable fastening in high-vibration applications. The combination of hex socket drive and knurled head texture allows for secure tool engagement while preventing slippage during torque application, making it ideal for maintenance-intensive operations where repeated disassembly is required.
Specification Summary & Compliance
This precision shoulder screw features Class 3A thread fit with 1/2"-13 UNC coarse thread specification and maintains tight dimensional control with shoulder diameter tolerance of -0.004" to -0.002" and shoulder length tolerance of -0.005" to 0.005". Manufactured in compliance with ASME B18.3 standards, the component also meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring both mechanical reliability and regulatory compliance for global industrial applications.
