Professional Applications & Engineering Value

This M6 shoulder screw is engineered to solve critical alignment and wear challenges in industrial applications. The precision-machined 70mm shoulder acts as a built-in spacer or pivot, eliminating the need for and cost of additional bushings. Made from 316 Stainless Steel, it offers exceptional resistance to chemicals and corrosion, making it a reliable choice for food processing, marine, and chemical equipment. The M6x1 coarse thread and Class 5g6g fit provide robust fastening, while the socket head with a knurled texture allows for secure tool engagement in confined spaces. This design delivers long-term durability and reduces maintenance in high-stress assemblies.
