• Secure and easy installation with a knurled socket head and 8mm hex drive, preventing tool slippage.
• Reliable thread engagement with Class 5g6g thread fit and coarse 1.75mm pitch for quick assembly.
• Durable and long-lasting performance backed by Rockwell B83 hardness and ISO 7379 manufacturing standards.
• Environmentally compliant design meeting RoHS 3 and REACH regulations for safe global use.

Professional Applications & Engineering Value

This M12 shoulder screw is engineered to solve critical alignment and wear issues in industrial applications. The 18-8 Stainless Steel material provides excellent corrosion resistance, extending service life in moist or chemically aggressive settings. Its 16mm shoulder diameter acts as a precise pivot or spacer, reducing wear on mating parts and ensuring accurate component positioning in assemblies like machinery linkages, conveyor systems, and rotating fixtures. The coarse thread with Class 5g6g fit allows for rapid, secure fastening, while the knurled socket head enhances grip during installation with standard hex tools. This combination delivers reliable performance in high-stress environments, minimizing maintenance and downtime.

Specification Summary & Compliance

The screw features a metric thread with M12x1.75 dimensions and Class 5g6g thread fit for precise tolerance. The shoulder diameter tolerance is -0.072 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm, ensuring accurate fit. It is manufactured in accordance with ISO 7379 specifications and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations.
