Blum Nickel-Plated Steel Clip Top Frameless Cam-mounting Plate (Pack of 5)

Ignore reviews that say the adjustment screws don't work. You MUST free the screws with correct driver before fitting the bracket. Then they work perfectly every time. I've fitted scores of these. Blum are the best currently on the market.

These are superior to the pressed steel mounting plates, and look much better too

Initially bought new hinges for a cupboard door that wouldn't close properly, however I then found that the new (Blum) hinges wouldn't fit the old hinge plates and the new hinges didn't come with hinge plates so had to buy these.According to the Amazon description the screw holes need to be 37mm in from the edge of the cabinet. There's not a lot of space inside a kitchen cabinet so I wasn't 100% confident in marking two holes at exactly 37mm and the exact distance apart, so also bought a cabinet hinge jig (also on Amazon and cheap so highly recommended) which had the holes marked at 37mm. Marked the holes using a hand rotary tool, drilled them out and the plates fitted fine. Had further problems with the hinges themselves but that's another story. Once fitted the door clipped on the these hinge plates nicely.

Photo is just one hinge of five, but they're all stuck
