Frequently Asked Questions

What are the key specifications for this double lock washer, and is it suitable for high-temperature or corrosive environments?
This washer is made from 316 Stainless Steel, which offers excellent corrosion resistance and can withstand temperatures up to approximately 1500°F for continuous service. It has a bore diameter of 0.866 inches, a thickness of 0.063 inches, and a plain finish, making it ideal for demanding applications in chemical, marine, or food processing equipment.
What are the typical applications for a DIN 25201 double lock washer, and how does its design improve performance?
The double lock (or double serrated) design provides superior vibration resistance by biting into both the bearing surface and the nut or bolt head, preventing loosening. It is commonly used in critical assemblies for machinery, pumps, valves, and structural components where secure, maintenance-free fastening is essential under dynamic loads.
How is this product packaged for order, and what is the minimum quantity I can purchase?
This washer is packaged in bulk quantities of 80 pieces per bag. Orders are typically fulfilled in these pre-set package quantities to ensure consistency and cost-effectiveness for industrial buyers. Please contact sales for pricing on multiple bags or pallet quantities.
