Hex Flange Nuts for Industrial & Electrical Fastening

TNHO hex flange nuts combine a standard hex nut with a built-in washer flange, eliminating the need for separate washers and simplifying installation. Manufactured via cold forging, they offer high strength, precise threads and consistent batch quality. Zinc-plated surface provides excellent anti-rust performance for long-term use in outdoor and industrial environments. We offer standard sizes like M8×16, M10×16 and support custom drawing specifications. Ideal for fastening in electric meters, metering boxes, power equipment and automotive applications, delivering reliable anti-loosening and anti-vibration performance.
