Professional Applications & Engineering Value

This M2 shoulder screw is engineered to solve critical alignment and wear issues in precision assemblies. The 316 Stainless Steel material offers exceptional resistance to chemicals and moisture, making it perfect for medical devices, food processing equipment, and marine applications. The 3 mm shoulder diameter acts as a precise locating dowel, eliminating the need for additional bushings and reducing assembly complexity. Combined with the Class 5g6g thread fit and coarse 0.4 mm pitch, it ensures rapid installation and maintains joint integrity under dynamic loads and vibrations. The hex socket head with a 2 mm drive is ideal for automated assembly systems, providing a reliable, high-torque fastening solution that minimizes downtime and maintenance costs.

Specification Summary & Compliance

This precision shoulder screw features an M2 x 0.4 mm right-hand coarse thread manufactured to Class 5g6g tolerance standards, ensuring consistent fit and function. The shoulder diameter is held to a tight tolerance of -0.072 to -0.01 mm, and the shoulder length is 16 mm with a tolerance of 0 to 0.25 mm for precise dimensional control. The component is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing it is free from hazardous substances for safe use in various industrial sectors.
