Hi
This weekend I'll be fixing some timber bearers onto an existing patio area prior to building a 6' x 4' garden shed.
I'll be using 6mm DeWalt Hex Head Blue-Tip Concrete Screwbolts for the first time and these obviously need a pilot hole through the slabs first.
I read conflicting advice on whether using an SDS drill on the percussion setting will crack the slabs or not. I was hoping to use masonry bits and the hammer action, but does anyone warn against this?
Secondly, these 6mm DeWalt concrete screws from Screwfix seem to need a 6mm pilot hole rather than something smaller which seems a bit counter-intuitive. Can anyone confirm this?
Thanks in advance
Ian
