Screwed

[MarineScott]

I need to attach (replace) a 12 ft 2x10 to my concrete block wall for my steps, and I want to know how many tapcon screws I will need, and how far apart to stagger them.

Just a bit more detail and a picture would help.

If it is functioning as a ledger I wouldn't use little blue tap cons. Through bolting is best (if you can get to the other side). Otherwise get some big 3/8 Hilti screws: https://www.lowes.com/pd/Simpson-St...VHCmtBh2KtygrEAQYASABEgLiH_D_BwE&gclsrc=aw.ds

Other-otherwise, build platform steps.
