Professional Applications & Engineering Value

This M6 shoulder screw, crafted from 18-8 Stainless Steel, is engineered to address critical alignment and wear issues in mechanical assemblies. The unthreaded shoulder provides a precise datum for locating parts, reducing wear on threaded components and eliminating the need for additional spacers or bushings. Its coarse pitch M6 x 1 mm thread ensures rapid assembly and high resistance to vibration loosening. The socket head with a hex drive allows for high torque installation in confined spaces, while the knurled head enhances grip during manual adjustments. Ideal for use in precision machinery, automation systems, and conveyor equipment, this screw delivers long-term reliability and simplifies assembly processes.

Specification Summary & Compliance
