TNHO Hex Flange Nuts for Industrial & Electrical Fastening
These hex flange nuts feature an integrated flange design for a larger bearing area, distributing pressure evenly and preventing loosening...
These large washer nuts are produced by cold heading and cold forging, featuring high strength, stable thread and long service life. Integrated large‑washer structure provides larger bearing area, better anti‑loosening and anti‑press performance. Available in carbon steel, stainless steel, brass; metric/inch sizes; zinc, nickel, black oxide, Dacromet finishes. Widely used for electric meters, metering boxes, power cabinets and auto parts.
Zhejiang TNHO large washer nuts adopt integrated large‑washer design, effectively expanding the stress area, avoiding surface indentation and improving anti‑vibration and anti‑loosening performance. Manufactured via mature cold heading/cold forging process with precise dimensions and stable batch consistency. We provide complete specifications covering metric and inch systems, multiple materials, surface treatments and strength grades. Support non‑standard drawing customization. Widely applied in electric meters, metering boxes, high/low voltage equipment, automotive and home appliances for reliable and safe fastening.
