Professional Applications & Engineering Value
This M20x2.5 shoulder screw is engineered to address critical challenges in precision machinery, automation systems, and heavy-duty assemblies. The 316 Stainless Steel material and Black Oxide finish provide exceptional resistance to corrosion and wear, extending service life in demanding conditions like marine or chemical processing. The 120mm shoulder length with minimal tolerance ensures exact component positioning, minimizing misalignment and vibration. Featuring a socket head with hex drive, it allows for high-torque installation in confined spaces, while the coarse thread design speeds up assembly without sacrificing strength. Ideal for use in robotics, conveyor systems, and fixture setups, this screw enhances operational reliability and reduces maintenance downtime.
Specification Summary & Compliance
This shoulder screw adheres to ISO 7379 specifications, with a shoulder diameter tolerance of -0.072 to -0.01 mm and length tolerance of 0 to 0.25 mm. Threads are Class 5g6g for metric coarse applications, ensuring precise fit. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting safe and sustainable industrial practices.
