Drill Pilot
When drilling pilot holes, how deep should the pilot hole be, same as screw, longer or shorter?
I will be installing a flooring transition from carpet to concrete and thus drilling into the concrete. So, I am mostly concerned with answers to that type of application; although, any and all answers are certainly welcome and will be considered when choosing the best answer.
In wood applications, I drill a pilot hole 1/2 to 3/4 of the length of the screw. hard wood – and I mean ‘hard’ not just the species type – gets drilled deeper than softer materials.
For concrete applications as you mention, I actually go deeper than the fastener… usually about 1/2 inch deeper. Concrete fasteners work by gripping the ’side’ of the hole – they dont grip at the tip, like wood screws do. Some fasteners require a certain depth – those should state that on their packaging.
