Introduction and use of cap nuts

As the name implies, the cap nut is a hexagonal nut with a cap. The function of this cap is to fasten the exposed part on the outside to prevent moisture or other corrosive substances from entering the inside to prevent rust, thereby improving itself and the connecting parts. Time of use.

Materials used for cap nuts: The main raw materials used in our products are: carbon steel (including low carbon steel, medium carbon steel, high carbon steel, spring steel), stainless steel (SUS201 SUS202 SUS302 SUS303 SUS304 SUS316 SUS416), Alloy steel, zinc aluminum alloy, easy car iron, aluminum, copper, plastic, PVC, bakelite, nylon, etc. (Guide: Matters needing attention when using electric screwdriver)

When we use cap nuts, under normal circumstances, the surface of cap nuts needs to be treated, including some surface treatment processes such as zinc plating, nickel plating, chrome plating and dacromet to make it more rust-proof and improve tightness. For the service life of the firmware, chrome plating is the best process among these surface treatment processes. The chrome-plated products not only have a smooth and bright surface, but also have a longer anti-rust and anti-corrosion time, which is comparable to stainless steel.

Cap nuts are mainly used on the tires and front and rear axles of automobiles, tricycles, and electric vehicles to fix the tires and the front, rear, left and right. It can also be used to fix the base of the street lamp holder that is often exposed to the sun and rain and some machinery In the device.
