In the electrical field, people use Non Marring Square Washers for grounding and bonding work.The washers' structural design allows them to fit tightly against the contact surface, ensuring stable current flow and reducing line resistance. The joints also have excellent anti-rust properties, effectively extending the service life of the components; and the washers are made of high-quality and highly conductive materials such as copper and brass, which can provide reliable protection for the safe and stable operation of electrical equipment.
Non Marring Square Washers are pretty common in furniture making too—especially when putting together frames or attaching legs. They have a bigger surface that spreads out pressure well, so they don’t damage wood or composite materials. That’s useful for stuff people use a lot, like office chairs or tables. The square design gives the gasket excellent assembly positioning capabilities, effectively ensuring precise alignment during installation. This feature not only significantly improves production and assembly efficiency, making the manufacturing process smoother and more efficient, but also reduces component loss due to installation deviations, thereby helping to extend the overall life of the furniture.

Q: Can you provide custom sizes for the Non Marring Square Washer outside of your standard catalog?
A:Absolutely. We specialize in custom fabrication. You can provide the specific outer dimension, inner hole diameter, and thickness requirements, and we can produce a non-standard Non-marring square washer to your exact specifications. Custom Non Marring Square Washer orders typically have a slightly higher unit cost and a longer lead time for tooling setup.
The shipping cost for Non Marring Square Washer depends on the shipping method, quantity and destination. For small batches or samples, international couriers like FedEx or DHL are common choices. The fee is calculated based on actual weight or volumetric weight (whichever is higher), with volumetric weight calculated as length×width×height (cm)÷6000. Generally, the cost per kilogram ranges from $15 to $30, and delivery takes 3 to 5 days.
For large quantities, sea freight is more cost-effective. If the goods fill a full container (like 20GP), the fee is charged per container, which varies by route—for example, a 20GP container from Shanghai to Hamburg costs around $1500. For less-than-container loads, the fee is about $50 to $100 per cubic meter. Sea freight takes longer, usually 2 to 6 weeks.
Additional fees may apply, such as fuel surcharges (adjusted monthly with oil prices), port handling fees, and customs clearance fees (around $100 to $300 per shipment). Storage fees will be incurred if goods are not picked up promptly upon arrival. It’s recommended to confirm the exact quote with the logistics provider, specifying the quantity and destination for an accurate estimate.
The packaging for Non Marring Square Washer is mainly designed for safe transportation and easy storage. For small quantities or samples, each piece is first wrapped in a thin plastic film to prevent scratches. Then they are put into small cardboard boxes, with foam or bubble wrap filled in the gaps to avoid collision during transit. Each small box can hold 50 to 100 pieces, depending on the size.
For bulk shipments, the small boxes are packed into standard corrugated cartons. The cartons are reinforced with tape around the edges to enhance sturdiness. Each carton’s gross weight is controlled within 20 to 25 kg, making it easy for handling. Sometimes, for long-distance sea freight, the cartons are further placed on pallets and wrapped with stretch film to keep them stable and prevent moisture.
No extra decorative materials are used in the packaging. All packaging materials are recyclable. If you have special packaging requirements, such as custom box sizes or waterproof packaging, you can discuss with the supplier in advance to adjust accordingly.
