This screw is strong so you can drive it just slightly below the surface of the deck board or you can screw it down 3/8 of an inch or more and plug the hole. On composite decking do not drill a pilot hole; instead, run the screw below the surface about an 1/8”, then hammer the fibers over the screw—it will basically disappear.
If you are using a biscuit jointer you need to make sure the bottom of your biscuit slot is about 3/8 of an inch from the bottom of the board on 5/4″ material and 5/16″ from the bottom on 4/4″ decking. The groove is 5/32″ x 1/2″ deep. You don’t want the leg to touch the joists and keep the clip from doing its job. If you are using slotted decking you should have plenty of room for the leg. We recommend using a top gauge on your biscuit jointer to set your slot instead of using the base plate.
Insert a clip in the slot and slide in a screw and drive the screw in till it just touches the top of the clip. The clips should be just level, do not over tighten or they will tip down and you will have a devil of a time sliding on the next board. After a few you will get the feel of it and they will go fast.
Slide the next board onto the clips at least halfway up and tighten the screws down. Don’t worry about the gap yet. Just make sure all the clips are in the slot. Tighten the screws enough so that The Deck CIip actually bows down some. On most clutch drills this is about 2/3 of the way up. Now just tap the board over with a mallet till you get the gap you want and The Deck CIip™ will hold it right where you want it! The screw head will nest right into the slot.
Continue this procedure till the deck is finished. On the last board you will need to drill and screw it down like you did the first board. That’s all there is to it! No pre-drilling, messy glue, or stripped out screws! You now have a beautiful deck installed with the best hidden deck fastener on the market.
