What size hole to predrill for Oly Log Screw
What size hole to predrill for Oly Log Screw
(OP)
I have limited edge distance and therfore predrilling is required for the use of Oly Log Screws.
The "minor root" diameter is 11/64". What size pre-drilled hole should I use if straight bit holes are to be used?
Main shank is 12/64.
