Professional Applications & Engineering Value

This M10 flange nut with black-oxide steel construction addresses critical challenges in industrial assembly where vibration resistance and corrosion protection are paramount. The integrated 17.8 mm flange distributes clamping force effectively across surfaces, preventing damage to soft materials and maintaining joint integrity under cyclic loading. The 12-point external drive design allows for higher torque application compared to standard hex nuts, making it ideal for high-stress applications in automotive, machinery, and structural assemblies. The fine thread pitch (1.25 mm) provides superior resistance to loosening in vibrating environments, while the Class 5H thread fit ensures precise mating with bolts for reliable performance in critical connections. This combination of features makes it particularly valuable for applications requiring repeated disassembly and reassembly without compromising thread integrity.

Specification Summary & Compliance

This metric flange nut features precise M10 x 1.25 mm fine threads with Class 5H thread fit per ISO metric standards, ensuring dimensional accuracy and reliable performance. The external 12-point drive accommodates standard industrial tools for consistent installation. Manufactured from black-oxide steel with right-hand threading, it complies with international metric specifications and is suitable for applications requiring RoHS and REACH compliance. The standard hex nut profile with integrated flange (17.8 mm diameter, 3.2 mm thickness) provides optimal bearing surface contact in accordance with industrial fastening requirements.
