• Secure and non-slip installation with the knurled head and 8mm hex socket drive, allowing for easy torque application without slippage.
• Accurate and consistent threading with Class 5g6g thread fit and M12x1.75 coarse pitch, ensuring easy assembly and vibration resistance.
• Compliance with international standards including ISO 7379, RoHS 3, and REACH, guaranteeing safety and environmental responsibility.

Professional Applications & Engineering Value

This M12 shoulder screw is engineered to address common challenges in precision machinery, such as misalignment and component wear. The 316 stainless steel material offers excellent resistance to chemicals and moisture, making it suitable for industrial applications in food processing, marine, and chemical industries. The black oxide finish enhances corrosion protection while maintaining a low-profile appearance. With a 180mm shoulder length and precise Class 5g6g thread fit, it ensures stable pivoting and rotational movement in assemblies like linkages, bearings, and gears. The knurled head and hex socket drive facilitate secure installation, reducing the risk of tool slippage during high-torque applications. This screw delivers reliable performance in precision engineering setups, minimizing downtime and maintenance costs.
