Attaching hardwware to block wall

I've just put up a slump stone block wall and will be attaching a gate to it. Is it better to run the screws into the blocks or the motar? Thanks

Wink block wall

It is better that you attach to the block, mortar at this point, is not strong enough yet for the rigors of a gate. If you have a block left over that you can use to determine, what part of the block runs solid through threw the unit, and place your screws into these area, would be better then putting the screws through the thin wall area if the block.

If this is the end of a wall and it was built properly, the cores will be filled solid with grout and rebar. You will be limited to using an anchor, and not any kind of a "toggle bolt". Even if the block was not filled the slump block walls are in excess of 1 1/2" and possibly 2".

Normally, you should drill into the mortar (especially for brick), but drilling into the block would be acceptable in this case.

I prefer to go into the block (provided it is solid grouted), aiming for a web if possible. The "blue screws" (Tapcons) work exceedingly well in concrete block.
