- Dimensional stability with tight shoulder diameter and length tolerances for repeatable precision in automated or manual assembly
Professional Applications & Engineering Value
This M3 shoulder screw is engineered to address critical alignment and durability challenges in industrial settings. The 316 stainless steel material offers exceptional resistance to chemicals, moisture, and high temperatures, making it suitable for precision machinery, automotive assemblies, and electronic enclosures. The knurled head and hex socket drive ensure secure fastening even in high-vibration environments, while the shoulder design provides a stable pivot or spacer, eliminating the need for additional components. By combining Class 5g6g thread fit with a coarse pitch, this screw facilitates quick installation and maintains integrity under dynamic loads, reducing maintenance downtime and improving operational efficiency.
Specification Summary & Compliance
The screw features a Class 5g6g thread fit per metric standards, with a shoulder diameter tolerance of -0.072 to -0.01 mm and shoulder length tolerance of 0 to 0.25 mm for high precision. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring the use of safe, restricted-substance-free materials in industrial applications.
