Although the surface of these 12-point specification washers and nuts may have a layer of anti-rust coating, our packaging is the main measure we take to prevent moisture from entering during transportation.
When we place the main cardboard boxes containing these Secure Locking 12 Point Washer Nut on the pallets, we will completely wrap them with high-quality waterproof polyethylene stretch film. This wrapping acts like a barrier - it can prevent rain, moisture, or accidental water from entering, thus protecting them from damage during transportation or storage. Therefore, when these 12-point specification washers and nuts reach you, they will not be rusty or corroded.

Our quality inspection of the Secure Locking 12 Point Washer Nut covers all aspects. The first step is to use certified raw materials.
At every stage of manufacturing these washers - such as cold forging, machining, tapping, and surface treatment - we conduct strict size checks and mechanical tests on each batch of products. We also use statistical process control (SPC) to monitor key indicators, such as thread pitch, hardness, and flange diameter.
This orderly production method ensures that each Secure-Locking 12 point washer nut can meet the requirements for strength and performance, no matter which one you choose.
People prefer the Secure Locking 12 Point Washer Nut for high-performance jobs—ones where there’s not much space and you really need it to resist vibration.
It has typical applications in many fields and can be used to manufacture supporting components for automobile engines and gearboxes, structural components that meet aerospace standards, core components that adapt to complex working conditions of heavy machinery, and special components for high-pressure fluid systems. This nut works well in these tough environments because it checks a few boxes: it gives strong clamp force, locks reliably, and doesn’t take up much space when installed. That way, it stays safe and holds up even under extreme conditions.
