Professional Applications & Engineering Value
This M5 shoulder screw is engineered to address critical alignment and pivot point requirements in industrial machinery. The 316 stainless steel material combined with a black oxide finish provides exceptional resistance to chemicals, moisture, and oxidation, making it suitable for food processing, marine, and chemical exposure applications. The precisely machined shoulder diameter and thread length allow for accurate component positioning, reducing wear on moving parts and minimizing assembly errors. Its hex socket head design enables high-torque installation in confined spaces, while the coarse metric thread ensures rapid and secure fastening. These features make it an ideal choice for precision assemblies, rotating shafts, and linkage systems where durability and corrosion resistance are paramount.
Specification Summary & Compliance
This shoulder screw features a Class 5g6g thread fit per metric standards, ensuring precise thread engagement. The shoulder diameter tolerance is controlled between -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm for consistent performance. It is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for use in environmentally sensitive and regulated industrial applications.
