Picking the right material for small washers comes down to what you need them to do. Carbon steel works for most everyday jobs and is cheap. In places where rust is easy to occur, such as food processing areas or by the sea, stainless steel (304 or 316) can resist rust and last a long time.Aluminum washers are light, which is great for aerospace stuff where weight matters.

Copper or brass washers let electricity flow through them, so these small washers good for electrical grounding setups. Nylon or plastic ones block electricity and help reduce buzzing noises in machinery. When things get really hot, try washers with silicone layers or ceramic bits,these keep their shape better under heat. If your project needs magnets to stick to something, you can choose iron-based washers.

Based on factors such as material strength, thermal expansion characteristics, and conductivity, choose a material that meets the project budget and safety regulations.

Maintenance

Taking good care of small washers helps them last longer. Check them regularly for rust, especially if it’s humid where they’re used. For metal washers, clean them with anti-rust cleaners and dry them completely. Add lubricant (like WD-40) again to keep their surfaces smooth. If a washer is worn out or bent, replace it right away to avoid problems with the joint.

Store extra washers in sealed containers to keep moisture away. For plastic or nylon washers, don’t leave them in direct sunlight or places that are super hot or cold. When you’re putting them on, use a torque wrench to make sure you don’t tighten them too much and squish the washers. In salty or chemical-heavy areas, go for coated or stainless steel washers. Also, jot down the installation date so you can stay on top of maintenance schedules. Following these steps keeps them working right and saves you from replacing them too soon.

Minimum order quantity

Q: What’s the smallest order I can place for small washers, and do they get cheaper if I buy a ton?

A:The MOQ (minimum order quantity) for basic washers of standard sizes requires between 1,000 and 5,000 pieces. Custom stuff? Expect higher MOQs.Costs also depend on the material you pick, how complex the coating is, and how many you’re buying,so simpler designs or bigger orders = better prices.

When asking for a quote, spell out exactly what you need: material, sizes, and finish (e.g., galvanized or PTFE) of the small washers. Xiaoguo® supplier can provide you with suitable products according to your needs, or provide small batch samples for testing first, and then place bulk orders after meeting the requirements.
