Professional Applications & Engineering Value

This M2 shoulder screw is engineered to solve critical alignment and fastening challenges in precision assemblies. The 316 stainless steel material provides exceptional resistance to chemicals, moisture, and high temperatures, making it suitable for demanding environments like medical devices, marine equipment, and food processing machinery. The integrated 3mm shoulder acts as a precise locating dowel, eliminating component misalignment and reducing assembly time. Combined with the Class 5g6g coarse thread and hex socket drive, it ensures quick, secure installation and maintains clamp load in high-vibration applications. This design is ideal for securing gears, pulleys, and linkages where dimensional accuracy and corrosion resistance are paramount.

Specification Summary & Compliance

This shoulder screw features an M2 x 0.4mm coarse metric thread with a Class 5g6g tolerance fit, ensuring precise thread engagement. The shoulder diameter is manufactured to a tight tolerance of -0.072 to -0.01 mm, and the shoulder length is held to 0 to 0.25 mm tolerance for consistent performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for use in environmentally conscious and regulated industrial applications.
