S-90368A114 M8 DIN 466 Thumb Nuts

Key Features & Benefits at a Glance

• Tool-free installation and adjustment with a knurled round head for superior grip in tight spaces or when gloves are worn
• Exceptional corrosion resistance from Black-Oxide coated 18-8 Stainless Steel, ensuring long-term reliability in harsh or humid environments
• Precise and reliable mating with Class 6H thread fit, providing consistent clamping force and reducing the risk of cross-threading
• Broad compatibility and interchangeability due to compliance with the DIN 466 standard and M8x1.25 mm coarse metric threading
• Durable, fully-threaded design offers maximum engagement strength and resists stripping under repeated hand-tightening cycles
• Compliance with major environmental regulations including RoHS 3 and REACH, making it suitable for global supply chains and sensitive applications

Professional Applications & Engineering Value

This M8 thumb nut is engineered to solve common assembly challenges where speed and tool access are limited. The Black-Oxide 18-8 Stainless Steel construction provides a robust defense against rust and chemical exposure, making it ideal for outdoor equipment, food processing machinery, and marine applications. The knurled round head offers a secure, non-slip surface for hand-tightening, which is critical for frequent adjustments or maintenance on jigs, fixtures, and access panels. Its fully threaded body and Class 6H metric thread ensure a precise fit on M8 coarse-threaded rods and bolts, delivering vibration resistance and load distribution that manual fasteners often lack. By integrating this DIN 466 standard component, engineers can streamline assembly lines, reduce dependency on tools, and enhance the service life of their products.

Specification Summary & Compliance

This thumb nut features M8 x 1.25 mm coarse threading with a Class 6H thread fit and right-hand thread direction, manufactured to DIN 466 specifications. Key dimensions include a 16 mm collar diameter, 30 mm head diameter, and 18 mm total height. The component is fully threaded and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free of restricted hazardous substances for industrial use.
