Professional Applications & Engineering Value
This M5 shoulder screw is engineered to address critical alignment and durability challenges in industrial applications. The 45mm shoulder length with minimal tolerance provides a precise pivot or spacer, eliminating misalignment in assemblies like machinery linkages, conveyor systems, and precision instruments. Made from 18-8 stainless steel, it offers superior resistance to rust and corrosion, extending service life in demanding conditions. The hex socket head allows for high-torque installation in confined spaces, ensuring a secure fit without protruding elements. With a coarse M5x0.8 thread and Class 6g fit, it facilitates quick assembly and maintains integrity under dynamic loads, making it a reliable choice for OEMs and maintenance teams seeking high tensile strength and long-term performance.
Specification Summary & Compliance
This precision shoulder screw features a Metric M5x0.8 thread with a Class 6g tolerance for accurate fit. The shoulder diameter is 6mm with a tolerance of -0.025 to 0mm, and the shoulder length is 45mm with a 0 to +0.05mm tolerance, ensuring precise dimensional control. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious and regulated industrial use.
