Professional Applications & Engineering Value

This M12 shoulder screw is engineered to address critical challenges in precision assembly and machinery. Made from 316 stainless steel with a black oxide finish, it resists corrosion from chemicals, moisture, and extreme temperatures, extending service life in industries like automotive, aerospace, and manufacturing. The coarse thread (1.75mm pitch) and Class 5g6g thread fit provide reliable engagement and vibration resistance, reducing maintenance needs. The knurled head and hex drive facilitate easy installation in tight spaces, while the 30mm shoulder length and 20mm shoulder diameter ensure precise alignment and spacing in rotating parts or linkages, minimizing wear and improving operational efficiency.
