Professional Applications & Engineering Value

Engineered for precision industrial applications requiring exact component alignment and vibration resistance, this alloy steel shoulder screw solves critical assembly challenges. The 25mm shoulder length with tight diameter tolerance provides accurate spacing in machinery, automation systems, and rotating assemblies. The M6x1mm coarse thread with Class 5g6g fit ensures reliable engagement in high-vibration environments, while the integrated nylon pellet locking maintains clamp load without compromising the black oxide finish corrosion protection. This combination addresses common failures in precision equipment where both positional accuracy and long-term fastening security are paramount.
