Professional Applications & Engineering Value

This M10 shoulder screw is engineered from alloy steel with a black oxide finish to address common industrial challenges like misalignment, corrosion, and mechanical stress. The precisely machined 30mm shoulder acts as a reliable pivot or axle in rotating assemblies, reducing wear on components and maintaining accurate positioning. With a coarse 1.5mm pitch and Class 5g6g thread fit, it ensures quick assembly and vibration resistance in heavy-duty equipment. The hex socket drive and knurled head facilitate secure installation in confined spaces, making it ideal for machinery, automotive, and automation systems where durability and precision are critical.

Specification Summary & Compliance

This shoulder screw features a metric M10x1.5 thread with Class 5g6g tolerance, a shoulder diameter of 13 mm (tolerance: -0.072 to -0.01 mm), and shoulder length of 30 mm (tolerance: 0 to 0.25 mm). It conforms to ASTM A108 specifications for material quality, and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in global industrial applications.
