1) What size drill bit do I need for my resin anchor studs?
The drill size for a resin stud is listed against each size. On smaller sizes you will need a drill size 2mm larger than the stud to give a 1mm clearance around it for the resin. On larger sizes this will increase to a 2mm clearance therefore a drill size 4mm larger than the stud.
2) What drive bit suits the screws I am buying?
The description of the screw will include a reference for the drive bit. PZ stands for Pozi, TX means Torx, PH is Phillips, TH is two-hole. The initials are then followed by a number that denotes the size. Our full range of drive bits is shown here
3) Which drill bit do I need for stainless steel?
