• Optimized for durability with a minimum shear strength of 35,000 psi, ensuring structural integrity in dynamic applications.

Professional Applications & Engineering Value

This M6 shoulder screw is engineered to address critical alignment and pivot point requirements in demanding assemblies. The precision-machined 316 Stainless Steel shoulder, with its tight diameter tolerance, acts as a reliable datum for rotating parts like gears, pulleys, and linkages, eliminating the need for separate bushings and reducing assembly complexity. The coarse metric thread (M6x1mm) and Class 5g6g thread fit ensure rapid, secure fastening into tapped holes, while the hex socket drive and knurled head provide superior torque transmission and handling in confined spaces. Its high tensile and shear strength makes it indispensable in machinery, automotive sub-assemblies, and conveyor systems where corrosion resistance and long-term reliability are paramount.

Specification Summary & Compliance
