Delivery time: 7-15 days (depending on quantity and process complexity)

IV. Notes
Color variations from batch to batch are normal. We recommend reserving color swatches for your first order.
Aluminum alloy gaskets are not suitable for extremely high temperature environments (>150°C). Stainless steel is recommended for high-temperature applications.
Urgent orders require advance notice and may incur expedited service charges.
V. Recommended Applications
Electronic products (e.g., PCB screw gap filling)
Bicycles/Drones (lightweight adjustment)
Mechanical equipment (anti-loosening and anti-corrosion gaskets)

Please contact us for further technical specifications or drawing templates. This solution balances versatility with customization flexibility, making it suitable for quick production integration.
When selecting, please note that aluminum alloy gaskets are not suitable for environments >150°C or for ultra-high-strength connections. It is recommended to use a torque wrench for optimal preload results.
