M4 x 8mm Captive Washer | A1 Stainless Steel | Vital Parts - WCT-M4-A1
Our M4 x 8mm Captive Washer is made from A1 Stainless Steel for use in general engineering and panel fastening applications. Featuring an 8mm outside diameter, 0.70mm thread pitch and 1.2mm thickness, this M4 washer is designed to remain paired with compatible captive screws across machinery covers, electrical cabinets, equipment housings and removable guards.
What Are Captive Washers?
Retained or captive washers are designed as part of a captive fastening arrangement, allowing the washer to stay on the screw when the assembly is loosened. This keeps related hardware together, supports faster refitting and provides a defined surface beneath the fastener head to help distribute clamping force.
Common Applications
- Machinery Covers: Suitable for removable panels and covers that require regular access.
- Electrical Cabinets: Keeps M4 washer hardware retained during installation and servicing.
- Equipment Housings: Provides a consistent bearing face beneath captive screw heads.
- Safety Guards: Useful where guard fixings must remain attached when the panel is opened.
