Inflated Procurement Costs

Are you overpaying for white washers for screws? Many distributors add a 30-50% markup. Sourcing directly from a factory eliminates this waste, but only if the quality is guaranteed.

Assembly Line Downtime

Inconsistent inner diameters or burrs on types of washers for screws cause jams in automated feeders. A single jam can halt a production line, costing $200+ per minute in lost output.

Corrosion & Field Failures

Using the wrong surface treatment (e.g., plain zinc instead of hot-dip galvanized) leads to premature rusting. This results in costly warranty claims and damage to your brand reputation in international markets.

Logistics & Compliance Headaches

Unreliable suppliers miss shipping windows, causing air freight costs to skyrocket. Non-compliance with RoHS, REACH, or ISO standards can get your goods blocked at customs.

10+ Years Export Expertise

Products shipped to 30+ countries across Europe, America, and Southeast Asia.

OEM/ODM Capabilities

Custom materials, finishes, and packaging to meet your exact specifications.

High-Speed Delivery

Integrated logistics network ensures 97% on-time delivery for bulk orders.

🟦 Flat Washers (DIN 125 / DIN 9021)

Used to distribute load over a larger surface area. Ideal for automotive chassis and construction steel structures. Our white washers for screws (zinc-plated) offer excellent corrosion resistance at a competitive price.

🟩 Spring Washers (DIN 127)

Provides axial flexibility to prevent loosening due to vibration. Commonly used in agricultural machinery and industrial pumps. Made from hardened 65Mn steel.

🟧 Lock Washers (Internal & External Tooth)

Designed to bite into the bearing surface, creating a mechanical lock. Essential for high-vibration environments like compressors and engines.

🟫 Belleville Washers (DIN 6796)

High-load conical springs that maintain tension under extreme thermal expansion. Critical for flange connections in pipelines and pressure vessels.

1. What are the standard sizes for white washers for screws?

Our standard white washers for screws (zinc-plated flat washers) range from M2 to M36, conforming to DIN 125 and ISO 7089 standards. Custom sizes are available for OEM orders with a quick lead time.

2. What is the difference between a flat washer and a spring washer?

A flat washer distributes the clamping load over a larger area, preventing damage to the material. A spring washer (DIN 127) is designed to apply a continuous axial force, preventing loosening due to vibration. Both are essential types of washers for screws in critical assemblies.

3. Can you provide OEM/ODM services for custom washer designs?

Absolutely. We specialize in OEM/ODM. Send us your drawings or samples, and our engineering team will provide a comprehensive solution, including material selection, tooling, and prototype delivery within 15 days.

4. What is your MOQ for standard types of washers for screws?

Our MOQ for standard types of washers for screws is typically 10,000 pieces per size. However, for sample testing or first-time collaboration, we can accommodate smaller quantities at a slightly adjusted unit price.

5. How do you ensure the quality of your washers?

We follow a strict 3-step QC process: (1) Incoming raw material inspection (chemical composition & hardness), (2) In-process dimensional checks using optical comparators, and (3) Final batch inspection per AQL 2.5 standards. We also provide ISO 9001, CE, and RoHS certifications with every shipment.

6. What is the typical lead time for bulk orders of white washers?

For standard sizes and finishes, lead time is 15-20 days after order confirmation. For custom dimensions or specialized coatings, lead time is 25-30 days. We offer split shipments to meet urgent production needs.

7. Do you offer any certifications for your fasteners?

Yes, we routinely provide ISO 9001, CE, RoHS, and REACH compliance certificates. Test reports for material composition (mill certificates) and dimensional verification are available upon request.

Purchasing Manager, Germany

"We evaluated three Chinese suppliers. Boen was the only one that provided complete technical drawings and certifications upfront. Their white washers for screws have exceeded our quality expectations."

Maria S.

Technical Director, USA

"The technical depth of their team is impressive. They helped us select the correct types of washers for screws for a high-vibration compressor application, and our field failure rate dropped to zero."

Ahmed K.

Operations Manager, UAE

"Fast delivery and excellent communication. Boen's logistics team coordinated a complex shipment to our site in Dubai, saving us 40% on freight costs compared to our previous supplier."
