Frequently asked questions

What is the CYF000040 washer used for?

The CYF000040 is a 4BA shakeproof (serrated) lock washer used in the rear side window fixings. The serrated faces bite into the mating surfaces to resist the fastener loosening under vibration.

How many of these washers are typically needed?

Rear side window fixings typically use one washer per fixing point, and there are usually multiple fixing points around each window, so check how many original washers you're replacing before ordering.

Can this washer be reused if the fixing is undamaged?

Serrated lock washers lose some of their bite once flattened, so if the original washer looks worn or crushed, it's best to fit a new one rather than reuse it to keep the fixing secure against vibration.
