M4 Finishing Washer | Black Nylon (Cupped - Straight)

With a M4 fixing size, 4.3mm internal diameter and 8.5mm outside diameter, this washer helps improve fastener seating in general engineering products, display hardware and fabricated housings. The profile is designed to support a professional finish around screw heads.

Manufactured from Nylon in Black, this cupped - straight finishing washer helps seat compatible screw heads neatly while reducing marking around the fixing point. The black nylon finish is commonly used where the washer remains visible and a discreet technical appearance is preferred.
