    Thanks, is that 10mm diameter?

    And I thought for joining two pieces of wood you only want partially threaded screws so it pulls into the second piece of wood...

    no its wire gauge no10 equivilant to around 5mm
    the shanks will be partly un threaded they just use a standard picture regardless off size

    you could use 4"nails as well :D

    I have a drill and a hammer, I know which I prefer to use :)

    So 100mm through 90mm of wood? I suppose if screwed at an angle it should be fine.

    sorry i misunderstood i thought you wanted to butt up to end rather than face to face
    go for 80mm or 3" if its 44 or 90mm and 3 1/2" iff its 46/47mm timber

    when you said studs they are normally 2x4" sawn at 47x97 ish rather than more expensive planed timber or cls at 38x89mm

    if its more than 15mm from an edge or 20 from an end you dont need a pilot
    otherwise 4mm drill on a 5mm/no10 screw

    Great thanks! And what about 8mm coach screws/bolts same principle? 1mm less or can it be two (have a 6mm drill bit).

    coach bolt/screw a different animal really wouldn't personally even think about them for this task
    one 8mm coach bolt would support 60 kg in a solid brick wall or in a 6x6" gate post
    what fixings do the the manufacturers off the bracket suggest you use ?
    also what size are the holes in the bracket as that governs you maximum shaft size ?

    The bracket came with 8mm (possibly 6mm) 50/60mm long bolts and washers for stud installation. The holes are more than 6mm for sure.

    Just for reference:
