How to Groove Your Own Deck Boards (It’s faster than you think!)


You might think that you need to have grooved deck boards to get a fastener-free deck surface with the TigerClaw TC-G fastener. But you can cut your own grooves in regular decking boards–and you can do it quickly!

The main tool required is a handheld router using a 5/32” bit (the video below shows the TigerClaw TC-G Slot Cutter). You’ll also want some safety glasses, a few clamps to hold down the decking boards on the deck surface, a tape measure, and a pencil.

As you see from the video, only a few steps are required:

  1. Measure 13/32” from bottom of board and mark with a pencil
  2. Adjust the router and do a sample cut at the pencil line and test to make sure the TigerClaw TC-G clip fits tightly in the groove as shown in the video
  3. After ensuring a correct measurement and cut, cut your grooves in the boards either at the location a groove is required or groove the entire board
  4. Install the TC-G clips as directed

The FastenMaster cut 8 slots in 12 seconds–only 24 seconds additional labor on every 20’ deck board and an extra 16 minutes for a 400 square foot deck. Much faster than installing deck boards with screws. (Not to mention those extra DIY bonus points you get for cutting your own grooves!)
