- High mechanical strength offering 70,000 psi tensile strength and Rockwell B83 hardness for reliable load-bearing applications.
- Secure and non-slip fastening facilitated by the knurled socket head and 10mm hex drive for firm tool grip.
- Optimized for metric assemblies with M12x1.75 coarse right-hand threads conforming to Class 5g6g fit for quick installation.
- Durable and compliant performance meeting ISO 7379 standards and environmental regulations like RoHS 3 and REACH.
- Versatile shoulder design providing a 30mm unthreaded section for smooth pivoting or spacing in mechanical linkages.
Professional Applications & Engineering Value
This M12 shoulder screw is engineered to address critical alignment and wear challenges in precision machinery. The 18-8 stainless steel material resists rust and chemical exposure, extending service life in demanding settings like automation equipment and food processing lines. Its 20mm shoulder diameter with controlled tolerance ensures exact bearing or bushing fit, minimizing vibration and part shift. The knurled socket head enhances grip during torque application, preventing tool slip in high-stress assembly. With a coarse thread pitch and Class 5g6g thread fit, it allows for rapid installation while maintaining secure fastening in dynamic loads, making it a reliable choice for pivots, axles, and guide pins where dimensional stability is paramount.
Specification Summary & Compliance
The screw adheres to ISO 7379 for dimensional consistency, featuring a Class 5g6g thread fit per metric standards. The shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, ensuring precision in high-tolerance applications. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), confirming its suitability for regulated industries without hazardous substances.
