Professional Applications & Engineering Value

This precision shoulder screw is engineered to solve critical alignment and pivot point challenges in industrial applications. The 18-8 stainless steel construction provides excellent resistance to corrosion and oxidation, which is vital for machinery operating in demanding environments like food processing, packaging, and outdoor equipment. The 16mm shoulder length acts as a precise datum for locating gears, bearings, or linkages, reducing side play and preventing fretting corrosion. Combined with the hex socket drive, it allows for secure, high-torque fastening in confined spaces, ensuring that assemblies remain rigid and accurately aligned. The M4 x 0.7mm coarse pitch thread offers rapid installation and robust holding power, making it a reliable choice for automated assembly lines and high-vibration settings where thread integrity is paramount.
