M2.5 x 5mm Captive Washer | A4 Stainless Steel | Vital Parts - WCT-M2.5-A4

Our M2.5 x 5mm Captive Washer is manufactured from A4 Stainless Steel, providing a compact retained fastening component for applications exposed to moisture or more demanding environments. The 5mm outside diameter, 0.45mm thread pitch and 1.0mm thickness suit precision captive screws used in outdoor electronics, marine instrumentation, sensor housings and frequently serviced equipment.

What Are Captive Washers?

A4 captive washers are designed to remain attached to compatible screws while providing the load-spreading function of a standard washer. Keeping the washer retained reduces loose hardware during maintenance, and the A4 stainless steel construction is selected where improved resistance to moisture and corrosion is important.

Common Applications

  • Outdoor Electronics: Ideal for compact enclosures and covers exposed to damp operating conditions.
  • Marine Instrumentation: Suitable for small instrument panels and control housings near coastal environments.
  • Sensor Housings: Keeps miniature washer hardware retained during calibration or servicing.
  • Precision Equipment: Provides a corrosion-resistant captive washer for M2.5 assemblies.
