When using 12" oc joist how often should you use fasteners? Every joist, or alternate between every other joist alternating between deck boards?
Asked by: tigerd
I would use on every joist if you have this. There is flex to the TREX boards themselves and I've had some almost curl if have a bit of a wave if you spread them out too thin. I wouldn't recommend every 24", so go with each.

What size gap is created between deck boards?

Using this fastener, what size gap is created between the deck boards. I recently used another universal fastener and although the deck looks aesthetically pleasing since you cannot see the screws, it does not look good when you can look in the gaps and see the fasteners and the joists. This is because the gap that's created is too big in my opinion. So I am looking for an alternative fastener.

do they rust?

Asked by: twgraber
No. The clips are some sort of tough plastic, and the included screws are stainless steel.

Like the idea of the hideaway fasteners, but the screws are totally worthless. Keep in mind that stainless steel has more nickel in it and the reason it doesn't rust, but it's also a softer mettle and these screws snap off CONSTANTLY. Most of the time you are lucky enough to get them to go in. I have a cordless drill that I have it set to not over tighten the screw, but I STILL have them break off. I was in a position where I had to take one of these decks up and move it to another location and wanted to save some money on the fasteners... DON'T... don't do this. The screws weaken each time you use them and your just going to have twice as many breaks the second time around. The head of the screw will just snap off, and then you have to pry out the plastic piece and snap the screw the rest of the way (or cut it out). Just not worth the time.

After 4 years, these plastic fasteners break due to heat and thaw of changing seasons and weight. I now have to pull up all decking to replace these only after four seasons. Go with metal fasteners.

Rated 5 out of 5 by from Worked great for me I was worried about these based on the other reviews and comments about how most the screws break and the bit strips. For me everything worked perfectly. My deck was 10 x 20 so I used 4 boxes and not a single problem, no broke screws, no stripped heads. I just kept in mind that the screws are stainless, that being said it is a weaker metal than standard screws. I started the screws with my drill on torque setting 2 to drive the screw head about an 1/8" to being flush, then after the next row was fastened the same way my helper stood on the boards and I drove the screws home with a 1/4 ratchet. Notice I did not try to draw the board down with the screw and did not use my battery driver to start the screws, of course both of those ways would have snapped screws. I did order the generic brand of these that were advertised to be designed for Trex but I found the spacer part was too short so it would give the proper 1/4" spacing but would leave a gap between the bottom of the fastener and the joist. For the money the Trex were only about $2.00 more but in the end they are worth it.

Rated 5 out of 5 by from Looks great and faster to install than standard deck screws! I installed 4 boxes of these with Trex Transcend on a new deck that I built. I didn't have a single screw break or strip. I'm not sure why others have had that problem, but it wasn't a problem for me. I installed them using a Ridgid 18v drill/driver on the "1" setting, which is the slower of the two settings. I would definitely recommend planing or shimming your joists to get them level. I had one spot where a low joist pulled down too hard on the board and it snapped the plastic bracket. I shimmed that one spot, and never had the problem again. As for visibility between the board gaps, I covered my joists with Vycor Deck Protector tape, which is black, so the fasteners blend in well. Hopefully it will also prevent joist rot for a very long time.

Rated 5 out of 5 by from Excellent Result, But Considerable Time Required I just finished redecking my 550 sq foot deck with Trex Transcend and these fasteners. If you are trying to use these to speed through a production job as a contractor, and/or use high speed/high torque tools to fasten, these are NOT for you. On the other hand, as a DIYer with a lot of time to complete my job, I found that with care and attention to detail, the finished product looked outstanding. I used a cordless drill driver set on a lower speed to drive the screws, and found the major problem to be due to operator error in not keeping the #1 square drive bit firmly seated in the screw head. The threads were aggressive, and without much pressure, one could seat the screws reliably. My only complaint was that for a plastic item, I thought the price was about 10-15% high.

Rated 4 out of 5 by from Soft screws? Stainless steel is the reason A number of reviewers complained about how soft the screws are, how they strip out easily, the heads break off, etc. This is not a problem with the Trex product --- it is the weakness of stainless steel, which is always softer than the standard steel used in most screws. You will encounter the same issue with every small head stainless screw. The toughness of the wood in your deck joists is a key factor, e.g. PT lumber that has aged and hardened. To prevent stripping / breaking, you may need to pre-drill a hole for each screw. We often have to take this extra step when we install new decking on an older deck, or PVC trim -- which also use stainless screws with a small head.

Rated 3 out of 5 by from Trex hidden fasteners.. be very careful As others have indicated the joists had better be level or you must shim be be level. If you tighten down on an un-level joist often the fastener will pull the Trex board right to the joist and create a downhill look if there are several joists in a row not level. So the lesson is level your joists first with shims or new joists. Trex boards are pretty flexible and show any variation more than cedar will. The screw heads will snap off or strip out pretty easily so use a variable speed driver, I also would not use the short bits included since that could mar your boards. The word "hidden" should be not used since they are quite visible primarily because of the large gap they create between boards....I suspect that is a partial solution to increase air flow and reduce the nasty green mold from latter versions of Trex. The large gap is fine for me but others may feel it is excessive. But...I have used other deck system fasteners that are much worse to install so even with all the faults I would still use them again. They just could be better.
