Large Plain Washers

Large plain washers have a larger outer diameter. This type of washer is round, more common, and has a simple structure. It is mainly used to increase the contact area between the screw and the connected object, reduce friction, and prevent falling off.

Material

Large plain washers use different materials depending on their job. Most folks go with:

1.Carbon steel (holds up well and costs less);

2.Stainless steel (won’t rust much);

3.Brass (lets electricity flow and doesn’t make sparks);

4.Nylon (lightweight and stops electricity).

Carbon steel ones are usually dipped in zinc to keep them from rusting. Stainless steel handles messy environments better. Nylon helps reduce noise in electrical setups.

The material you pick affects how much weight the washer can handle. Steel washers can handle a lot of stress, while plastic ones are better for light-duty jobs. Some washers are heat-treated to make them harder for really high-pressure situations.

You can track where the materials come from, which helps make sure they meet industry standards like RoHS or REACH. This way, they're safe and good for the environment.

Application

Large plain washers are used everywhere in different industries. In cars, they hold engine parts in place and soak up vibrations. In construction, they strengthen steel beams and stop bolts from slipping. In electronics, nylon plain washers keep circuits insulated. HVAC systems use them to seal pipe connections, and when assembling furniture, they protect wood from screw damage. For marine use, stainless steel plain washers are chosen because they resist saltwater.

You’ll find them in agriculture machinery, renewable energy setups, and household appliances too. Whether it’s for heavy machines or delicate equipment, plain washers provide reliable fastening that lasts, cutting down on maintenance and downtime.

Quality standards

Q: Do large plain washers comply with international standards like ISO or DIN?

A: Large plain washers follow standard specs like ISO 7089, DIN 125, and ASME B18.22.1,basically common international rules that:

1.Set exact sizes (hole width, total width, thickness);

2.Require materials with the right strength;

3.Can be used normally within the pressure range without damage.

They also need to pass environmental checks like RoHS/REACH,these basically confirm the washers don’t contain harmful chemicals.

If you need to customize washers according to your region or industry, Xiaoguo® manufacturers can meet your specific requirements and customize or recommend them according to the actual usage scenarios, size, material and other requirements. After communicating the needs, determine which standard needs to be met and determine the quantity, place an order for delivery.
