Posting the noobiest question of my life...

[Davy Jones]

What screws do i need to mount my RO/DI to the cinderblock walls in my basement? Do normal screws work?

 

[Dave Cureton]

Something specific to masonry would be your best bet. I would use something like this: http://www.homedepot.com/p/Tapcon-3...Head-Concrete-Anchors-75-Pack-24355/100136988

No they don't. You need those plastic inserts for those screws to go into. They to make concrete screws. There are also concrete anchors that are more permanent.

Thanks! Ill pick up some concrete type anchors at my local home depot.

There is no universally agreed upon "correct" way to mount something in masonry....choose what makes the most sense based on the quality of the wall (100-year-old mortal isn't too stable, for example) and the available selection of anchors at the store.

My house is all block, and I have mounted plenty of things to cinder block with concrete screws. If the item never moves or has additional forces against it I find they hold well, if the above isn't true they seem to get looser over time. I've had success in solving that issue using some epoxy in the hole along with the screw.

Tapcons or anchors. I would use tapcons though. Just pre drill the hole alil smaller then the screw. I do alot of concrete work in my trade.

I like TapCon's too, but all methods have some pretty specific plusses and minuses.

That is why I suggest that you have to account for your specific wall when you pick your method.

From the Tapcon Tapcon® Concrete Screws website:

HOLDING STRENGTH
• Holding values of the Tapcon® screw will differ based on the strength of the base material that the screw will be installed. A rule of thumb is that the harder the base material then the better the holding values.
• The Tapcon® screw is considered a light duty fastener and should only be used in light loading applications, such as an electrical junction box to concrete or wood to brick.
• The Tapcon® screw should never be removed and replaced back in to the same hole because the holding values may deteriorate to zero.

More traditional split anchors can put enough pressure on an old brick to split it, but lots of people use them in other scenarios:

I don't know enough to know really.. the house was built in the early 70's, the room is in the basement and the wall is cinderBlock. it looks like it has that moisture sealing paint on it or whatever lol helpful I know

I guess I mean use your judgement: If it seems weak or crumbly whle you're working on it, it is. If it's seems strong, it is.

Thanks for the help everyone! I got it mounted last night using the plastic anchor things and screws. broke 3 of the little drill bits drilling a pilot hole into the block so i guess you can say it was solid lol

Glad you got it hung. If you need to hang anything else on the wall ,a hammer drill will work way faster for you to drill the holes.

Glad you got it hung. If you need to hang anything else on the wall ,a hammer drill with impact rated drill bit will work way faster for you to drill the holes.

Added a little bit.

Thanks for the tip, I dont plan on mounting anything else to block anytime soon but will keep it in mind for next time!

Makes a huge difference.

Yea... always use a hammer drill when drilling in masonry.
