## Questions & Answers

**Q: How long are thr screws**
A: These screws are 2-3/4".

**Q: I have 2X10’s underneath with Trex on top, will i be okay screwing these down or will they penetrate past the 2X10?**
A: The 2x10s should be stood up with the 10" (9-1/2") upright.  The screws will securely fasten the trex boards and will not penetrate through the wood.  I used the grooved Trex decking and used the clamps to tie down the boards.  I only used these screws on the inner and outer pieces.  Use the bit that comes with the screw to automatically countersink the screws and use the color matched decking "dowels" to hide the screws.  I really don't think you want to use these screws for all the boards.

**Q: do these require pre-drilling?**
A: The bit countersinks the screw about 1/4" below the top of the deck board.  You can buy Trex (or presumably other) decking plugs that fit into the holes.  No pre -drilling required.

**Q: Are they stainless steel?**
A: No, these are coated carbon steel.
