Key Features & Benefits at a Glance
- Enhanced corrosion resistance with zinc plating for extended service life in demanding industrial environments
- Superior torque transmission from the external square drive, preventing tool slippage during high-tension assembly
- Reliable thread engagement with Class 6H fit, ensuring consistent clamping force and vibration resistance
- Optimized for rapid installation using coarse (1.25 mm pitch) metric threads, reducing assembly time in production lines
- Guaranteed mechanical performance meeting Class 04 strength requirements for general engineering applications
- Global compliance assurance with RoHS 3 and REACH regulations, making them suitable for international supply chains
- Precise dimensional compatibility per DIN 562 standard, ensuring interchangeability with other metric fastener systems
Professional Applications & Engineering Value
This M8 square nut delivers critical engineering value in machinery assembly, structural frameworks, and equipment manufacturing. The zinc-plated steel construction provides a cost-effective barrier against rust and chemical exposure, while the external square drive design allows for high-torque application with standard wrenches—eliminating rounding issues common with hexagonal fasteners. Its coarse metric thread (M8 x 1.25 mm) maintains holding power in vibratory environments, and the Class 6H thread fit ensures precise mating with bolts without galling. These characteristics make it ideal for automotive jigs, conveyor systems, and agricultural machinery where durable, metric fasteners are specified.
Specification Summary & Compliance
This square nut conforms to DIN 562 dimensional standards with M8 x 1.25 mm coarse metric thread and Class 6H thread fit tolerance. The fastener meets Class 04 mechanical property requirements and carries full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations. Physical dimensions are 13 mm width and 4 mm height with right-hand thread orientation.
