Frequently Asked Questions (FAQ)
-
What is the difference between double coil and single coil spring washers?
Double coil spring washers have two turns, providing higher spring force and better locking performance compared to single coil washers, which are more suitable for lighter applications. -
Are these washers suitable for outdoor use?
Yes, 304 stainless steel offers excellent corrosion resistance, making them ideal for outdoor, marine, and humid environments. -
Can I order custom sizes or quantities?
Absolutely. We offer customization for sizes, pack quantities, and even special materials. Please contact our sales team for details. -
What standards do these washers comply with?
They are manufactured to meet DIN 127 and ASME B18.21.1 standards, ensuring compatibility with standard metric and inch fasteners. -
How do I choose the correct size?
Select a washer that matches the bolt or screw diameter. For example, an M8 washer fits an M8 bolt. The inner diameter should be slightly larger than the bolt shaft. -
Are these washers reusable?
While they can be reused, it is recommended to replace them after disassembly for optimal locking performance, as the spring tension may degrade over time. -
Do you provide samples?
Yes, we offer samples for testing. Please contact us with your requirements, and we will arrange shipment. -
