• Easy installation and removal using a standard 10 mm hex drive, allowing for efficient assembly with common tools.
• Accurate thread engagement with Class 5g6g thread fit and M12x1.75 mm coarse pitch, reducing cross-threading risks and improving fastener reliability.
• Compliance with environmental regulations including RoHS 3 and REACH, making it suitable for global supply chains and sensitive applications.

Professional Applications & Engineering Value

This M12 shoulder screw is engineered to address critical challenges in machinery, automation, and structural assemblies where precise component alignment and corrosion resistance are paramount. The 316 stainless steel material offers excellent resistance to chemicals and moisture, preventing failure in corrosive settings like marine or chemical processing equipment. The black oxide finish not only enhances aesthetics but also adds a protective layer against abrasion and galling. With its knurled head and standard shoulder design, it ensures secure placement in pivoting mechanisms, bearings, and linkages, reducing wear and simplifying maintenance. The coarse thread pitch and Class 5g6g thread fit provide reliable fastening in high-vibration environments, making it a top choice for industrial fasteners requiring durability and precision.

Specification Summary & Compliance

This shoulder screw features a Class 5g6g thread fit per metric standards, ensuring tight tolerances for consistent performance. Key dimensions include a 30 mm head diameter, 14 mm shoulder length with a tolerance of 0 to 0.25 mm, and a shoulder diameter tolerance of -0.072 to -0.01 mm for precise assembly. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious industrial applications without hazardous substances.
