Black Heaye Hexagon Nut

The black heaye hexagon nut is thicker than the standard nut and has thick threads for quick installation. It is available in sizes from M10 to M30 and is suitable for use with most heavy duty bolts.

Product details and parameters

Black heaye hexagon nut is used on heavy machinery, construction RIGS or equipment that produces vibration and noise. Mechanics use them on truck frames, excavator parts or high-strength industrial equipment. You can use them with class 8 bolts because they can withstand pressure without slipping. Please carry a wrench with you. Their size requires force to tighten.

The black heaye hexagon nut is used for black steel beams, railings or outdoor sculpture. The matte finish hides scratches and prevents the nut from fading in the sun. Farmers use them for tractor attachments or barn hinges. If using near salt water, you only need to apply grease to the thread.

Truck drivers use the black heaye hexagon nut to secure flat loads or repair trailer parts. Their thick material can withstand potholes and highway bumps. They can be used with hardened bolts for fastening or suspension. The ratchet wrench allows for faster adjustments during pit stops. If you are driving in a saline area, please occasionally wipe the nut.

Product surface treatment

The surface treatment of Black Heavy Hexagon Nut is mainly for rust prevention, which is a basic process for this kind of nut. The most common way is black oxidation treatment. It uses chemical reaction to form a thin black protective film on the nut surface. This film can separate the metal from air and water, so the nut is not easy to rust. The treatment process is simple, no extra coating is added, so it won’t change the nut’s size or affect its use. The surface after treatment is matte black, no bright luster. We just follow regular operation steps to make sure the protective film is evenly covered. Sometimes, we also do simple oil coating after oxidation, which can enhance the rust-proof effect a little. This kind of surface treatment is suitable for daily use and general industrial scenarios. It doesn’t have any special functions, just to make the nut usable for a longer time. The treatment meets common industry standards, so the nut can match with bolts normally and won’t cause problems during installation.

Why They Beat Standard Nuts

The black heaye hexagon nut has a thicker construction and can withstand torque 2-3 times higher than normal nuts. Its surface conceals scratches, making it ideal for use on visually visible parts where aesthetics are important. If the thread is stuck, soak the nut in penetrating oil.
