- Rockwell B55 hardness provides excellent mechanical strength and resistance to deformation over time.
Professional Applications & Engineering Value
This M12 shoulder screw is engineered to address common challenges in precision assembly and machinery, such as misalignment and component wear. Made from 18-8 stainless steel with a black oxide finish, it offers reliable corrosion resistance in demanding settings like automotive, robotics, and industrial equipment. The hex socket head and knurled texture ensure secure tool engagement, reducing installation errors. With a 35mm shoulder length and Class 5g6g thread fit, it provides accurate alignment for rotating parts, minimizing vibration and extending service life. Ideal for applications requiring high tensile strength and dimensional stability, this screw supports efficient maintenance and long-term operational reliability.
Specification Summary & Compliance
This shoulder screw features a metric thread with M12 size, 1.75mm pitch, and Class 5g6g thread fit for precise tolerances. Dimensions include an 18mm thread length and 35mm shoulder length with minimal tolerances (e.g., shoulder diameter: -0.04 to -0.01 mm). It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards, ensuring environmental and safety adherence. Manufactured to high mechanical standards, it meets specified hardness (Rockwell B55) and strength requirements for industrial use.
