TIMBERTECHCONCEALoc Hidden Fasteners with Screws - Box of 175

Excellent for maintaining spacing between decking and securing to deck framing.

Very very expensive for what they do, but you gotta have them if you're building a Timbertech deck. They work very well, very few broken screws. No predrilling needed unless you are screwing into knots.

Finally got down the new decking today. Bought TimberTech Pro decking at Lowes. They do not offer the CONCEALoc fasteners though. They do offer cheaper generic mild steel fasteners instead of the powder coated stainless these are made of. These are around 50% more than the mild steel ones but since we bought 30 year decking thought we aught to have fasteners that would last that long.

Fasteners work as advertised. Easy to install. I did round off the bit that came with them, but I had a replacement so finished using that. It would be nice if they included two bits per box.

Worked great for the Azek deck boards. Tried the Trex fasteners, they left too wide of a gap between the deck boards, approximately a 3/16" gap. The TimberTech CONCEALoc Fastener leaves about an 1/8" gap. Looks much better. Would buy again.

My deck was wobbly using these fasteners had to change all of them to trex. Trex was half the price. Wish I had started with them instead of waiting $125

These clips work well and are easy to install. I really like that the gap left between boards is smaller than some of the cheaper plastic clips.Now for the bad...these clips are outrageously expensive. I spent over $1000 on just these clips for my deck. I do have a very large deck but at about $1 each, these are too expensive.

Cheaper online than the store. It does what is supposed to. Make sure you screw at the correct angle to prevent damaging the screw.
