NL1/4″ double-stack self-locking washer is a metal washer, usually used to connect bolts and nuts. It consists of two circular or oval rings of different sizes, the inner ring is slightly smaller than the outer ring, and passes through multiple tiny The flanges and grooves are joined together. These flanges and grooves are designed so that the washer can be compressed and fit snugly under the nut, providing extra tightening force and preventing loosening. In addition, using the double layer design also Can provide better shock and vibration resistance.

NL1/4″ means that the size of the washer is 1/4 inch (about 6.35mm), and NL means that the washer adopts the “Nord-Lock” brand, which is a double-stacked self-locking washer type.

What are the dimensions and weight of an NL 1/4" double stack self locking washer?

The NL 1/4″ double stacked self-locking washer measures 1/4″ (approximately 6.35mm) and has an outer diameter of approximately 0.52″ (13.2mm) and an inner diameter of approximately 0.26″ (6.6mm). It is approximately 0.08″ thick inches (2.03 mm) or so.

Plus, this model is generally pretty light at around 0.03 ounces (0.9 grams). However, the specific weight may vary due to factors such as materials and manufacturing processes.

What are the physical characteristics such as material and hardness of NL1/4" double-stacked self-locking washers?

NL1/4″ double stacked self-locking washers are usually made of high-strength steel or stainless steel, these materials have high corrosion resistance and mechanical strength. The specific material depends on the application needs and environmental conditions. For example, in high temperature or chemical substances When used in an environment, stainless steel is more suitable.

Also, the hardness of this model is usually between HRC 44-51. This means it is stiff and strong enough to withstand high pressures and heavy loads while maintaining its shape and function. In addition, it has some elasticity and can resist vibration and shock.

What is the service life of NL 1/4" double stack self locking washers?

The service life of NL1/4″ double-stacked self-locking washers varies depending on the conditions of use and the environment. Generally speaking, under normal use, its service life should be relatively long. This mainly depends on the following aspect:

Use environment: If it is used in a harsh environment, such as a place with high temperature, humidity or chemical corrosion substances, its service life may be shortened.

Machining Quality: Poor machining quality or improper installation can cause the gasket to become overly compressed or deformed, affecting its performance and service life.

Working load: If it is loaded beyond its carrying capacity, it will also accelerate its wear and aging.

How to install and use NL1/4" correctly?

When installing NL1/4″ double-stack self-locking washers, the following points should be noted:

Clean and inspect the surfaces of gaskets and connecting parts prior to installation to ensure they are clean and flat.

Install the washer on the bolt or nut and place it in the desired position.

Properly turn the bolt or nut until the desired tightening force is achieved, making sure not to overtighten.

Check that the gasket is installed correctly. If the gasket is not fully compressed or deformed, it can cause a loose connection or a poor seal.

If connecting parts need to be removed and reinstalled several times, use new gaskets.

When using NL1/4″ double-stack self-locking washers, the following points should be noted:

Make sure that the fastening force of the connected parts is proper and within their load-carrying capacity to avoid overloading and wear of the gaskets.

Regularly check the condition of connecting parts and gaskets to ensure they are functioning properly.

Avoid using in environments with extreme temperature, humidity or presence of chemical corrosive substances, so as not to affect the performance and life of the gasket.

What are the advantages and disadvantages of NL1/4" double-stack self-locking washers?

Self-locking function: NL1/4″ double-stack self-locking washer can use its internal special structure to lock automatically after the tightening force reaches a certain level, preventing loosening and rotation of nuts or bolts.

Shock absorption performance: Due to its double-stack structure, NL1/4″ double-stack self-locking washers can provide better shock absorption and cushioning effects, thereby reducing the wear and corrosion of the connecting parts.

Strong durability: NL1/4″ double-stack self-locking washers are usually made of high-quality materials, which have good durability and relatively long service life.

However, NL1/4″ double stack self-locking washers also have some disadvantages:

Installation needs attention: Due to its self-locking function, it is necessary to ensure that the fastening force is correct and uniform during installation, otherwise the connecting parts may be broken or damaged.

Higher price: NL 1/4″ double stack self-locking washers are more expensive compared to traditional flat washers, which may increase manufacturing costs.

Limited Locking Force: NL 1/4″ double stack self-locking washers have limited locking force and are unable to withstand extreme loads. In some special applications, other types of washers may be required.

What does the NL 1/4" double stack self-locking washer do?

NL1/4″ double stacked self-locking washer is a kind of washer for joints, it has the following functions:

Anti-loosening: Due to its special internal structure design, the NL1/4″ double-stack self-locking washer can be locked automatically after the tightening force reaches a certain level, thus preventing the loosening of the connection and the rotation of the nut or bolt.

Shock absorption and cushioning: Through its double-layer structure design, NL1/4″ double-stacked self-locking washers can provide certain shock absorption and cushioning effects, thereby reducing the vibration and impact of the connecting parts during movement.

Strong durability: Made of high-quality materials, NL1/4″ double-stack self-locking washers have good durability and corrosion resistance, and relatively long service life.
