Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 Stainless Steel and passivated finish for long-term reliability in harsh environments
- Precise alignment and positioning enabled by the 6mm shoulder diameter with tight tolerance fit for reduced assembly errors
- High-strength performance with 70,000 psi tensile strength and Rockwell B79 hardness for demanding mechanical applications
- Secure, slip-resistant fastening using the 3mm hex socket drive for reliable torque transmission and easy installation
- Consistent thread engagement with Class 6g metric coarse threads (0.8mm pitch) ensuring vibration resistance and durability
- Environmental compliance assurance meeting RoHS 3 and REACH standards for safe use in regulated industries
- Smooth surface finish on the shoulder and head to prevent damage to mating components during operation
Professional Applications & Engineering Value
This M5 shoulder screw is engineered to address critical alignment and corrosion challenges in precision assemblies. The 316 Stainless Steel construction with passivated finish provides exceptional resistance to chemicals, moisture, and oxidation, making it ideal for marine, chemical processing, and food equipment applications. The precise shoulder diameter (6mm with tight tolerance) acts as a pivot or spacer, eliminating misalignment in rotating parts, linkages, and jigs. Combined with the Class 6g coarse thread and hex socket drive, it ensures quick assembly, high clamp load retention, and reduced wear in high-vibration environments like automation systems and machinery.
Specification Summary & Compliance
This shoulder screw conforms to metric thread standards with M5x0.8mm coarse pitch and Class 6g thread fit for consistent performance. The shoulder diameter tolerance is -0.025 to 0 mm, and shoulder length tolerance is 0 to 0.05 mm, ensuring precise dimensional control. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, guaranteeing environmental safety and regulatory adherence for industrial use.
