- Enhanced durability from Rockwell B55 hardness, providing excellent resistance to deformation under load
- Global compliance assurance meeting RoHS 3 and REACH regulations for safe, sustainable use
Professional Applications & Engineering Value
This 3/8"-16 UNC shoulder screw is engineered to solve critical alignment and load-bearing challenges in precision assemblies. The 18-8 stainless steel material offers excellent corrosion resistance, making it suitable for machinery, automation systems, and outdoor equipment. The precision shoulder acts as a pivot, bearing surface, or locator, eliminating the need for additional bushings and reducing assembly complexity. The hex socket head with knurling ensures a firm grip during installation, preventing tool slippage in high-torque scenarios. With its Class 3A thread fit and coarse thread spacing, it provides rapid assembly and superior vibration resistance, which is vital for maintaining integrity in dynamic industrial applications.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 3A thread fit for high precision. The shoulder diameter tolerance is -0.004" to -0.002", and the shoulder length tolerance is -0.002" to 0.002", ensuring exact dimensional control. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming its suitability for regulated industrial and international markets.
