We do not recommend pre-drilling as there can be irregularities in casting that can produce small variations in the size of the holes.
All clamps come with stainless steel grub screws fitted. If full tightened using a ratchet key to a torque of 4.1kg/m (29ft/lb), the grub screw is capable of withstanding an applied slipload of 900kg.
