  • Nice fastners
Material Type: Galvanized Steel Size Name: 0.374"
A little expensive, but these work great..wish I bought them before.

  • Just what I needed, high quality!
Material Type: Galvanized Steel Size Name: 0.334"
Great product. I wasn't sure how well the included bit would work, but it had a nice tight fit with the screw and didn't slip out when I was screwing in the fasteners. These hidden fasteners have a firm hold and don't leave much of a gap between the boards, which is fantastic.

  • Absolute best hidden fasteners for Trex deck!
Material Type: Galvanized Steel Size Name: 0.255"
I spent hours researching and ordering like ten different hidden fasteners, because I didn't like the Trex hidden fastener, the gap was too large between the planks (3/16" to 1/4"). So I tried out all the ones I bought and this Fruh one is hands down the best, sturdy, solid construction, easy to install, and the gap is half the size, about 1/8" (between 3-4mm) which looks so much nicer on my deck. No worries of kids fingers getting stuck or high heels tripping because of the gap. Water can still go down easily and the deck can breathe so mold won't grow (if there is no gap, then that could happen). I saved you a lot of time, trust me, if you are looking for a smaller gap than Trex, you found your fastener. Remember to choose the taller one for Trex, 8.5mm high fits the grooved edge perfectly. ... show more

  • Happy with Cost and Quality
Material Type: Galvanized Steel Size Name: 0.374"
We were debating on redoing a wood deck to composite for a non profit. Cost was a factor and was holding us up on doing the project. We were happy to find these clips here as they cut our cost nearly in half from in-store prices. I used these with TimberTech grooved boards and they fit correctly and can get tight against the groove. It takes more than one person to do a great job holding the board tight while securing the next row of fasteners. So I would definitely recommend also buying the spacers they sell. Which are pretty cheap for a pack of 20. Agree with others that one per joist is definitely a requirement unless you have incredibly level joists. Otherwise due to the flex in composite decking you will hear it slap the joist while walking on the place you didn't put a fastener. ... show more

  • PERFECT FIT!
Material Type: Galvanized Steel Size Name: 0.374"
Excellent hidden deck fasteners. Since they offer three sizes, I measured the bottom groove thickness and matched it to the next taller clip. Perfect fit and super sturdy clips.
