Frequently Asked Questions
Q1: What is the difference between a double coil spring washer and a standard spring washer?
A: A double coil spring washer has two intertwined coils, offering higher spring deflection and load capacity compared to a single coil washer. This makes it more effective in absorbing vibration and maintaining bolt tension in demanding applications like automotive assembly.
Q2: Can these washers be used in corrosive environments?
A: Yes. We offer various surface finishes such as zinc plating, black oxide, and phosphate. For higher corrosion resistance, stainless steel material (e.g., SUS304) is available upon request. Please specify your environmental conditions when ordering.
Q3: Are custom sizes available?
A: Absolutely. We can customize inner diameter, outer diameter, thickness, and material to meet your specific requirements. Minimum order quantities may apply for custom sizes.
Q4: Do you provide samples for testing?
A: Yes, we offer free samples for evaluation. You only need to cover the shipping cost. Contact our sales team to arrange sample delivery.
Q5: What is the typical lead time for bulk orders?
A: Lead time depends on order quantity and specification. For standard sizes, it is usually 15–25 working days after order confirmation. Custom orders may take 20–30 working days. We will confirm the timeline at the time of quotation.
Q6: Can these washers be reused after disassembly?
A: Yes, due to the robust double coil design, the washers retain their elasticity after multiple load cycles, making them suitable for applications where parts may be removed and reassembled. However, we recommend inspecting them for any deformation before reuse.
Q7: Do you have any quality certifications?
A: Our factory follows strict quality control procedures. Specific certifications such as ISO or other standards can be provided upon request, depending on the customer's requirements. Please discuss during the inquiry.
Q8: Which ports do you ship from?
A: We ship from major Chinese ports including Tianjin, Qingdao, Shanghai, and Foshan. We can also arrange shipment to any port worldwide based on your preference.
