I have found Two more solid looking 8mm Screws that fit holes and some heavy duty plasplugs.
Accepts screw sizes 8,10,12 - Use Drill No14 7mm
A fine pilot hole - what do I use to create one of those?
Thanks have a 'hammer' drill supposedly, just tried and the so called masonry bit went up the brickwork, and is now buckled
Thanks just tried with a 5mm bit, has made a hole a few mm into the brick and was smoking towards the end the drill bits I've got are rubbish.
Am gone purchase a decent drill and drill bits - any Recommendations appreciated.
Also do you always use one size smaller drill bit than the screw/plug you are using
I.E. if you have an 8mm plug/screw - you should use only a 7mm drill bit?
Well spotted regarding the pre drilled hole - if that’s what it is, and it sure looks like itAre you sure that they are 8mm screws? 8mm is massive. Did you measure the shank or the screw head?
In your photo it looks like the dart board has the holes for the fixing screws already. If so then no need to pilot.
After marking out the holes I normally use a screw and hammer to punch a tiny dent in the brick to stop the drill bit slipping.
BTW, if the bricks are extremely hard (eg engineering bricks) you will need to use an SDS drill.
