What fittings are these?

Kaizersoze81

Hi,

Had a doorbell pre fitted when we bought the house, but I want to change it now. I’m trying to remove the old doorbell fitting, but can’t figure out what’s holding it in. Are they square Allen key fittings , or something else?

Thanks

Those are screws . Get the right bit and it will come off

Thanks, I’ve never seen screws with a square head before. Now to try and fit out what size they are
Are they called torx screws?

They're not very common, just called square head screws I believe, or sometimes Robertson head. Torx is something else entirely.

You might find a suitable bit hidden away in some of the security bit sets you can get for undoing all those weird and wonderful anti tamper screw heads found in electronic equipment.

....and you'll never use them again. Get a small flathead that fits diagonally across the head. That'll do it and then just replace them with regular Philips head.

Well that depends ... I've found uses for many of the anti-tamper bits in my set, but then I do have a thing for taking stuff apart, and occasionally putting it back together again ... if I'm lucky

jack of all

You're better off going into a proper electrical wholsalers and getting a square drive/ robertson bit for the job. They come in two common sizes and there's a good chance any other electrical fittings in your house are fixed in position with them anyway, so handy to have the proper bit.

Nah, specifically referring to the Robertson bits for the non-tamper heads. I don’t think I’ve used them since I relocated alarm sensors on Windows about 20yrs ago. Ive a decent bit set which also also has ‘torq:set, bits (google them, they’re weird) which have never been used along with a couple of other obscure types.
