• Superior torque transmission and grip from the knurled, hex socket head and 10mm hex drive, reducing tool slippage.
• Reliable and coarse thread engagement with the M12x1.75 Class 5g6g metric thread, facilitating faster assembly.
• Durable and hardened material rated at Rockwell B79, providing excellent wear resistance and longevity.
• Compliance with global environmental standards, being RoHS 3 and REACH compliant for safe and responsible use.

Professional Applications & Engineering Value

This M12 shoulder screw is engineered from 316 Stainless Steel to solve critical challenges in industrial settings, such as corrosion from moisture, chemicals, and saline conditions. The precision shoulder with a 20mm diameter and tight tolerance ensures accurate alignment in assemblies, reducing wear and misalignment in machinery, robotics, and automotive systems. The coarse metric thread (1.75mm pitch) and Class 5g6g thread fit provide secure fastening in high-vibration environments, while the knurled socket head enhances torque application, preventing stripping and improving maintenance efficiency. Ideal for applications requiring high tensile strength and durability, this screw supports reliable performance in demanding engineering projects.

Specification Summary & Compliance

This shoulder screw adheres to metric system standards with an M12 thread size, 1.75mm coarse pitch, and Class 5g6g thread fit for precise ISO-compliant threading. The shoulder diameter tolerance is controlled between -0.072 to -0.01 mm, and shoulder length tolerance from 0 to 0.25 mm, ensuring high dimensional accuracy. Manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, it is free from hazardous substances, supporting safe and sustainable industrial use.
