Composite Deck Screws


The manufacturer only talks about pre-drilling at the ends of boards. I was told that pre-drilling would ease the install process, although it adds time. I think I'll try drtbk4ever's advice and try drilling only the composite.
I'm still left with about 6 screws standing tall. Any ideas to remedy this?
Thanks again,
John

Composite Deck Screws


fill 'em in and drive 'em agin'!
i'd try pot-sticker size doweling and don't predrill since it's already weakened.
use a flat ended scrap dowel and shove the pieces down enough to just fill the PT part (1"?), this should allow them to tighten properly.

Composite Deck Screws


The only problem with that is that once they spin, then they don't want to come out. I don't know if that is because of the right and left handed threads on each screw or what. The ones that drive correctly seem like they would be able to be driven right through the board. I'm not real sure I'm a fan of these screws. When they work right they really do look good, when they don't ...

Can you get a tack puller under the head and pry up as you spin the screw?

slide a hard drive ceramic magnet to the end of your driver bit, touching the screw head and then hit reverse (forward?) slowly, that should help pull it back up. once you can get a hammer or crowbar or pliers on it, just pull it up.

Composite Deck Screws


the only thing I can think of has been stated already. When you pre-drilled you ended up pre drilling into the joist. When you pre drill your deck boards, only drill the deck boards..never the joist. You need a tight fit on the joist.

If you have trouble pre-drilling too deep, set your bit in farther so it cannot go past the decking when you predrill.

As far as someone telling you to not use an impact the only reason not to use an impact is you can strip or over screw very easily as it has so much torque. However with a little practice you can get the right amount in and know when to stop. It is MUCH better then a drill..trust me

By the way...TORX ROX

Sorry forgot to add this in.... take out the rest of the screws in the board that has the screws that are stripped.... once they are the only ones left, carefully have someone pull up the deck board to put pressure on the screws ( DO NOT YANK IT OUT) just enough pressure to make the screw bite a bit and then reverse the screws out...they should come right out (need to start with the ones closest to the raised end of the deck board you are lifting and work your way to the farthest screw).

Thanks rahfiki. You are correct I WAS drilling into the joists (heavy on the was). Luckily I have only started screwing the boards down. We did the ends and the middle. I figured I could get all the boards on and then come back and do the rest of the screws (bunches of 'em). I'll try your method on the stripped ones. That seems like a fairly straight forward method.
Thanks again,
John

Composite Deck Screws


Sorry it took so long to get back, things always seem to come up. Anyways, I was going to start taking out the good screws in order to get to the stripped ones and didn't have to go very far. When you back out the good one the board wants to climb the left handed top threads and applies enough pressure on the stripped one to allow it to be removed. The process messes with the appearance of the good one slightly, but all in all, it seems to work just fine. I will do the rest of them and continue on ONLY PRE-DRILLING THE DECK BOARDS . I appreciate all the help and comments.
Thanks again,
John

Report back in once you have completed that deck and please post a photo. I would love to see how it turns out.

Cheers.

Composite Deck Screws


OK I spoke to soon (that's normal) on the ease of getting the screw out. The first one I did worked perfect, after that no go. I stumbled across a method by accident. OK, really it was frustration. I had a stripped one that would do nothing but spin. I got frustrated and spun it forward at high revs., the left handed threads caught and jumped the head up clear of the board. It was enough that I could get my small pry bar under it and then reversed it out of the hole. . I got the rest out that way.
Thanks again all for the help.
John

Hey all,
Just a little follow up and closure. I finished 1-1/2 weeks ago, but just got around to uploading pictures. . I want to thank all who gave advice. It helped a ton. Once I stopped pre-drilling into the joists everything worked great. I didn't have 1 screw spin after you showed me the light. Thanks again. Here's a couple of pictures showing a during and almost complete. The after was taken before the deck had been washed off. It's pretty dusty. Thanks again all
John
