You should see screw threads sticking out past the bit, but the bit should hide the rest of the screw.
Why Pre-Drill a Pilot Hole? Since screws have a sharp end to them, why is it necessary to pre-drill holes to accommodate the fastener? It is true that the self-tapping screws can easily penetrate into softwood with the help of a drill driver or an impact driver.However, when it comes to larger diameter holes and tough materials such as hardwood and metal you will need to drill pilot holes.
I am thinking about drilling pilot holes up from the bottom through the new deck boards to line up the the holes with the old ones.

If you are building a deck yourself, it is better to pre drill the holes for composite, although this isn’t necessary for PVC decking. Pre drilling gives the screw more space which makes it less likely to break and also leaves less mushrooming on the surface of the deck. PVC decking has a different cell structure with more “give” so to ...

Dec 30, 2019·First, estimate the entry point based on the length of the screw. Then start the bit at a right angle to the wood at this point (top photo). As soon as the drill bit engages the wood, tilt the bit to the desired angle and finish drilling the pilot hole (bottom photo). Now drive the screw into the angled pilot hole to complete the job.

A real simple technique I use is to hold up the drill bit and the screw. Hold the shaft of the drill bit up in front of the screw. You should only be able to see the threads of the screw (and maybe a bit of the screw). If you can't see the threads the drill bit is too big. If you can see too much of the screw, the bit is too small. I hope this ...
