• High mechanical strength offering 70,000 psi tensile and 35,000 psi shear strength for reliable performance in heavy-duty assemblies.
• Precise component alignment enabled by the 20mm shoulder diameter and 40mm length, ensuring accurate positioning and reduced wear.
• Secure and easy installation with a 10mm hex socket drive and knurled head, allowing for high torque application and improved grip.
• Accurate and reliable threading with Class 5g6g metric coarse thread (M12x1.75), ensuring consistent fit and reducing cross-threading risks.
• Compliance with environmental and safety standards including RoHS 3 and REACH, making it suitable for regulated industries.

Professional Applications & Engineering Value

This M12 shoulder screw is engineered to address critical challenges in precision machinery and industrial equipment. The 316 stainless steel material provides excellent resistance to chemicals and moisture, preventing failure in corrosive settings. Its black oxide finish not only enhances aesthetics but also minimizes friction during assembly, extending service life. The knurled head and socket drive design allow for secure handling in high-vibration environments, while the precisely machined shoulder acts as a pivot or spacer, maintaining alignment in rotating assemblies like conveyor systems or automotive jigs. By integrating a Class 5g6g thread fit and coarse M12x1.75 thread, it ensures quick installation and reliable load distribution, reducing downtime in production lines.

Specification Summary & Compliance

This shoulder screw adheres to metric system standards with a Class 5g6g thread fit for precise tolerance. Key dimensions include a shoulder diameter of 20 mm (tolerance: -0.072 to -0.01 mm) and shoulder length of 40 mm (tolerance: 0 to 0.25 mm), ensuring exact fitment. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming it is free of hazardous substances for safe use in industrial and electronic applications.
