Bit of advice please. I bought a packet of plugs and screws from B&Q but have used far more screws than plugs and want to replace them. I have measured the screws and they are 60mm long and look like Goldscrews. Is the diameter the measurement across the outside of the thread, in which case I reckon its 5mm, or across the shank in which case I reckon its a 4mm? Thanks for any help.
Buy browns and use a 7mm masonry bit which is standard but I tend to use reds and a 6mm bit, What are you doing?
The diameter is indeed the outside of the thread, Yours screws are 5x60. In hard masonry, you might like to make the hole a tad bigger than 7mm(if using brown plugs). Mr. HandyAndy - Really
You're over thinking it. Just get some brown plugs and stick those 60mm screws in them. I prefer 6mm drill bit so they're tight and bang plugs in with hammer.
Not really, I just had a screw that I wanted to replace with the same but didn't know how to spec it. Agree with everything you say so probably just misunderstanding. Thanks for the reply.
