Professional Applications & Engineering Value
This precision shoulder screw delivers exceptional engineering value in applications requiring exact component alignment and rotational control. The 18-8 stainless steel construction provides excellent corrosion resistance, making it ideal for machinery, automation systems, and equipment exposed to moisture or chemicals. The M6x1mm coarse pitch threads with Class 6g fit ensure reliable fastening while the precisely machined 8mm shoulder diameter maintains accurate positioning of moving parts. The socket head hex drive design allows for high torque application in confined spaces, solving common assembly challenges in precision manufacturing, robotics, and industrial equipment where component misalignment can cause operational failures.
Specification Summary & Compliance
This metric shoulder screw features M6x1mm coarse pitch threads with Class 6g thread fit per ISO standards. The shoulder diameter maintains tight tolerance of -0.025 to 0 mm with shoulder length tolerance of 0 to 0.05 mm for precision applications. Manufactured from 18-8 stainless steel with Rockwell B55 hardness and 70,000 psi tensile strength. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations.
