Professional Applications & Engineering Value
These M2 shoulder screws deliver critical precision in applications requiring exact component positioning and rotational stability. The 316 stainless steel material combined with black oxide finish provides superior resistance to chemicals, moisture, and oxidation, making them ideal for medical devices, optical equipment, and electronic enclosures operating in corrosive conditions. The 35mm shoulder length acts as a precise axle or pivot point, eliminating the need for additional bushings and reducing assembly complexity. With their hex drive socket head and knurled texture, they ensure secure tool engagement during installation, preventing cam-out and maintaining torque accuracy in automated or manual assembly lines.
Specification Summary & Compliance
This precision shoulder screw features M2 x 0.4mm coarse metric threads with Class 5g6g fit, ensuring dimensional accuracy and interchangeability. Shoulder diameter tolerance is maintained at -0.072 to -0.01 mm with shoulder length tolerance of 0 to 0.25 mm. Manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, guaranteeing safe use in global industrial markets.
