Replacement Fixing Screws for Yale Lock

[Drdub]

The lock is a Yale Type 91 and the 2 small screws that fit the mechanism to the backplate on the door need replacing.

Each screw is 8mm long by 3 mm in diameter approx. I've tried my local B&Q but all the screws are in plastic bags and it's impossible to tell if they will fit. There's no detailed product information that I can find on the Yale web site. Any ideas what size these are?

Use a rivet gun with rivets. If and when you need to remove the lock you can just drill out the rivets.
