Professional Applications & Engineering Value
This precision shoulder screw is engineered to solve critical alignment and pivot point challenges in machinery and automation. The 1/2" shoulder diameter provides a stable bearing surface, reducing wear on mating parts and ensuring precise component location in assemblies like linkages, gears, and rotating fixtures. Manufactured from 18-8 stainless steel and finished with a TiCN coating, it offers exceptional resistance to corrosion, galling, and abrasive wear, significantly extending component life in demanding applications. The Class 2A thread fit and coarse 3/8"-16 UNC thread facilitate quick assembly while maintaining high strength and vibration resistance, making it an ideal choice for industrial equipment, automotive jigs, and conveyor systems where reliability and durability are paramount.
Specification Summary & Compliance
This shoulder screw features a 3/8"-16 UNC thread with a Class 2A thread fit for standard industrial compatibility and precision. The shoulder is manufactured to precise tolerances (Diameter: -0.001" to 0", Length: 0" to 0.002") to ensure accurate fit and function. The material meets a Rockwell B55 hardness and 70,000 psi tensile strength, confirming its suitability for high-stress applications. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and global market acceptance.
