Product Description

We have summarized the advantages and disadvantages of the Carbon Steel DIN 463 Tab washers with long and short tab and provided you with usage guidance.

【1】Advantages

（1）Reliable anti-loosening performance

It adopts mechanical locking, not relying on friction or elasticity. It completely prevents rotation and will not loosen even in a vibrating environment.

（2）Simple structure, low cost

The Carbon Steel DIN 463 Tab washers with long and short tab is formed by a single-piece stamping process, without complex structures. It uses less material and has a manufacturing cost lower than that of dedicated anti-loosening nuts.

（3）Resistant to high and low temperatures

Made of all-metal material, without any plastic or rubber components. Carbon steel can withstand -50°C to +200°C, while stainless steel can reach -160°C to +500°C.

（4）Not affected by lubrication or oil contamination

The locking effect of the Carbon Steel DIN 463 Tab washers with long and short tab does not depend on the friction coefficient. Even if there is oil or lubricant on the contact surface, it will not hinder the locking.

（5）The installation status is clearly visible.

The bent ear pieces can be seen at a glance, and quality inspection does not require special tools.

（6）Can be used in conjunction with standard nuts.

No need to purchase special locking nuts. Suitable for both ordinary nuts and bolts.

（7）High adaptability

The long ears can fit into slot holes, the edges of workpieces or irregular protrusions, and there is no strict requirement for the installation surface.

【2】Disadvantages

（1）Single-use

The ear piece will permanently deform after bending. When disassembling, the Carbon Steel DIN 463 Tab washers with long and short tab must be damaged and it cannot be reused.

（2）Not suitable for equipment that is frequently disassembled and assembled.

Each maintenance requires replacing new washer, which increases procurement costs.

（3）The workpiece needs to provide fixed points.

The long ears must be bent into the slot or clamped to the edge.

（4）During the bending operation, the ear piece may be damaged.

If the operation is improper, cracks or even fractures may occur at the root of the ear piece, resulting in the failure of locking.

（5）Not suitable for bolts that are too large or too small.

For M3 size, it is too small and the ear piece is difficult to operate; for sizes above M45, there are too few standard products, increasing the customization cost.

（6）The appearance is not aesthetically pleasing.

After bending, the ear pieces are exposed and have irregular shapes, which are not suitable for consumer products that have requirements for appearance.
