Professional Applications & Engineering Value

This M12 shoulder screw is engineered to address critical alignment and mounting challenges in industrial applications. The long, precision-machined 160mm shoulder acts as a sturdy axle or spacer, maintaining exact positioning in machinery, linkages, and rotating assemblies. Made from 316 stainless steel, it offers excellent resistance to chemicals, moisture, and oxidation, which is vital in food processing, marine, or chemical exposure settings. The knurled socket head with an 8mm hex drive provides a firm grip for tools, reducing the risk of cam-out during installation and enabling secure fastening in high-vibration environments. Its M12x1.75 coarse thread and robust tensile strength ensure that the screw remains securely fastened, supporting heavy loads and reducing maintenance needs in automated systems and precision equipment.
