Professional Applications & Engineering Value

This M12 shoulder screw is engineered to address critical alignment and strength challenges in industrial applications. The 316 stainless steel material provides excellent resistance to corrosion and chemicals, making it suitable for machinery, automotive, and marine environments where exposure to moisture is common. The black oxide finish adds an extra layer of protection against rust while reducing glare. With a coarse thread (M12x1.75) and Class 5g6g thread fit, it ensures quick assembly and reliable holding power, minimizing the risk of strip-out in high-vibration settings. The 110mm shoulder length and precise 16mm shoulder diameter allow for accurate positioning of moving parts, such as in pivots, gears, and linkages, reducing wear and enhancing operational efficiency. This precision shoulder bolt delivers consistent performance, supporting B2B procurement needs for durable, compliant fastening solutions.
