6 Tips to Reduce Wood Splitting
Test Pieces
Test the joint with some scrap workpieces cut from the same stock as your fi nal workpiece.
Make sure you’re using Kreg Screws
Kreg screws have several features designed to limit/eliminate wood splitting in your joints.
Use Fine Thread Screws in Hardwood
Coarse Thread screws displace more wood thanks to a more aggressive thread pattern.
Screw it In, Back it Out
By driving your screw half way in, back out, and then in again, you’ll reduce excess wood in the
hole and reduce the chance for splitting.
Reduce Friction
By applying some bee’s wax or other lubricant to the screw, you’ll reduce the friction of the
screw entering the workpiece.
Clamp, Clamp, Clamp
Correctly clamping your joints reduce workpiece movement/vibration, both of which can cause splitting.

For the best results, place the Face Clamp™
on the joint directly over the center of the
joint line. Make sure the large pad of the
clamp is on the face side of the joint (opposite
the Pocket-Holes) to keep the workpieces
perfectly fl ush. Clamp fi rmly to reduce the
possibility for workpiece movement.
