I have 5 x 10mm expansion bolts that expand into 15mm holes, to attach a plate above my patio doors (38mm x 75mm x 2.6m) into brick. Onto the plate I'll be attaching eight cross beams of a pergola (well, sort of - it's more a frame for a vine to grow across, looking like a pergola), each beam about 2.5m long and same dims as the one attached to the house. I already have in place the uprights and beam for the opposite end of the pergola.
Am I ok to attach the bolts into the bricks, approx 1/3 up from the bottom of the bricks to avoid the voids in the bricks? I know not to over-tighten. Or am I better using concrete screws (which I also have), since it's not going to be holding a lot of weight?
Thanks for any advice,
Chris
