Professional Applications & Engineering Value
This 316 stainless steel shoulder screw delivers critical performance in precision assemblies where alignment and durability are paramount. The 10-24 UNC coarse thread with Class 3A fit ensures secure fastening in high-vibration environments, while the substantial 3 1/4" shoulder length provides accurate component spacing in machinery, automation systems, and rotating assemblies. The knurled head texture combined with hex socket drive enables reliable torque transmission during installation and maintenance. Engineered to ASME B18.3 specifications, these shoulder screws maintain dimensional stability under heavy loads, making them ideal for industrial equipment, manufacturing fixtures, and precision instruments requiring repeated disassembly and reassembly cycles.
