With Ipe and other tropical hardwoods, do I need to pre-drill?
You will generally not have to pre-drill IPE using the special Deckmaster® screws with the type 17 auger points. However, you will need to pre-drill IPE at splices or near (2-3″) any butt ends of the boards, or if the IPE happens to be very dry. It is best to test to be sure. Moisture content may vary widely from the time the IPE is harvested to the time it is installed, so there is no definitive answer. Additionally, grain patterns may affect the possibility of splitting but the frequency is very rare. [Back to Top] 10.
