how flush to make screws for hardibacker

[Bud Cline]

Centuries ago when I thought I wanted to be a professional Deck Builder I would buy top-o-the-line deck screws (nothing but the best for my jobs/customers) only to have the damned things weep black stains everywhere inside the first year.

I wouldn't trust a deck screw or the BS that comes with them for an instant.


A GOOD CBU screw has many features.

Corrosive resistant, (coated)
pierce point for stabbing into board,
square tip for drilling cement board,
hi-lo threads for gripping, (two sets of threads)
head-gafs for clearing the "set",
wide head for better holding power,
square drive.

I wouldn't recommend venturing too far off course to save a penny a screw.

I agree and would never use anything but CBU screws for CBU's. As anyone who has worked with Hardibacker can tell you, it is a pain in the ass with CBU screws. The deck screws I use are coated, square drive, and pierce pointed. Hardibacker isn't as prone to fastener pull through as CBU's and hi/lo threads will cause Hardi to rise up on the screw as it is screwed down. I use a deck/drywall screwgun and never have to use a hammer. They hold tight.

[Scooter]

Hate 'em, especially with Hardibacker. I find that when I get close to flush, the screw actually backs the board out from the framing. Could never figure out why. It just does.

I use only nails. They are one fourth the price, faster, and are always flush.

[Bud Cline]

This "pull thru" thing. When's the last time anyone doing tile work and using any kind of a tile underlayment board experienced a nail or screw head "pull thru"?

What's that all about anyway. Hardi is the only company that uses that information to promote their stupid product that I know off and it's just plain nonsense. Nonsense I tell ya.

Pull thru indeed.





nonsense

Hey Bud,
Saw that you mentioned "square drive" CBU screws, where can they be had? All I can find are phillips which are trash. I had thought about using the decking screws but would perfer the other option.
thanks

I used to buy them (big bucks) mail order from MeFeeley's then our local Big Box turned up with them one day so that's where I go to get ripped off.

Your in Denver I see, do have Menard's there, that's who carries them here.

"Oh man" it just hit me.....my local lumber yard (mom & pop) brought those things in for me and I keep forgetting to buy them there.

[Outlander]

We don't have a Menard's here, are the a hardware chain? I've checked the regulars, i.e. HD, Lowes etc to no luck. I have one other place to check, hardware store that has some of the strangest things, just have to get off my butt and drive to Boulder to see.

Does MeFeeley's have a web site?

You better go visit Mom & Pop, sounds like they luv you, to get you such nice things.

Thanks

[Bud Cline]

See what you can find here, I don't have time right now but if you don't come up with something I'll see what I can find. I know those things have to be in your area somewhere.

Hey...Do I smell smoke?



McFeeley's:

Thanks Bud, I guess I'll take a ride to Boulder this weekend if the smoke clears.

Boy !!!! they are high at McFeeleys. Per screw price for 1000 is what I pay now in quantities of 100 but there phillips, then to add shipping, Whoa......

thanks again

Hey Bud and everyone else,

Found a supplier for CBS screws for cement Fiber Board with Quadrex heads (similiar to Square drive" with good pricing, $19.38 per 1000 in boxes of 8000. There are several variations, looks like the Quadrex doesn't have the Hi-Lo thread though.

or 888-726-2221

Also came across an auto feed drive atachment that looks interesting.

The screws I now have (scratching my memory here) come in a five pound box with a count of 580 on the average.

Twenty-five bucks!!!

[John Bridge]

C'mon Bud. Go ahead and tell him about your roofing nailer that you use on backer board. Go ahead, tell him.

[Bud Cline]

I don't use a roofing nailer I use a stapler, screw the walls, staple the floors.

[Outlander]

Yeah, I know, sometimes Jiff peanut butter works when you run low on thinset. We can have lunch and continue to work. Tricks of the trade and all that.
