- Environmental compliance meeting RoHS 3 and REACH standards for safe use in regulated industries
Professional Applications & Engineering Value
This M4 shoulder screw is engineered to address common challenges in precision assemblies, such as misalignment and corrosion-induced failure. The 316 stainless steel material, combined with a black oxide finish, provides superior resistance to chemicals and moisture, extending service life in demanding settings like machinery, automotive, and marine equipment. The 17mm shoulder length acts as a precise spacer or pivot, reducing stress on threaded sections and minimizing wear. With a knurled socket head and 2.5mm hex drive, it ensures secure torque application without cam-out, making it ideal for applications requiring repeated adjustments or high vibration resistance. This design supports efficient maintenance and reduces downtime in industrial shoulder screw applications.
Specification Summary & Compliance
The screw features Class 5g6g thread fit per metric standards, ensuring precise tolerance for reliable fastening. Shoulder dimensions include a diameter of 5 mm (tolerance: -0.072 to -0.01 mm) and length of 17 mm (tolerance: 0 to 0.25 mm) for consistent performance. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious industrial use.
