Professional Applications & Engineering Value
This M20 shoulder screw delivers exceptional engineering value in precision assembly applications where alignment accuracy and corrosion resistance are critical. The 316 stainless steel construction combined with black oxide finish provides superior protection against chemical exposure and atmospheric corrosion, making it ideal for marine, chemical processing, and food manufacturing equipment. The precisely machined shoulder diameter of 24mm with tight tolerance control ensures perfect bearing surfaces and pivot points in machinery assemblies, while the hex drive design with knurled head prevents slipping during high-torque installation. The Class 5g6g thread fit and coarse thread pitch facilitate quick assembly in automated production environments, reducing installation time and improving manufacturing efficiency.
Specification Summary & Compliance
This metric shoulder screw features precision Class 5g6g thread fit with M20x2.5 coarse threading and maintains critical shoulder dimensions including 24mm diameter (-0.072 to -0.01 mm tolerance) and 16mm length (0 to 0.25 mm tolerance). Manufactured in compliance with ISO 7379 specifications for dimensional accuracy and mechanical properties. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global markets.
