Operation - Kreg K4 Owner's Manual

Operation

To create strong joints, you'll set your jig to match the thickness of the workpiece and
the length of the screw.
1
Set the Drill Guide
a. For a strong joint, the screw should exit close to the center of the drilled
workpiece.
b. To adjust the pocket-hole position, unscrew the drill-guide locking pin (F). Then
align the mark on the side of the drill guide (E) that matches the thickness of the
workpiece with the top edge of the guide socket (B).
c. Screw in the locking pin (F).
2
Choose a Screw
a. Coarse Thread
Due to the large diameter and thread pitch, our No. 8 coarse-thread
screws offer a strong hold in softwoods and composite materials. Use in
woods such as pine, cedar, basswood, poplar, plywood, MDF, and particle
board.
b. Fine Thread
Because the smaller diameter and thread pitch, our No. 7 fine-thread
screws reduce the chance of splitting the material, we recommend them
for hardwoods. Use in woods such as ash, oak, maple, walnut, hickory,
cherry, mahogany, and birch.
NOTE All Kreg pocket screws feature a deep square drive that improves
driver engagement and reduces the possibility of cam-out. The self-
tapping auger point eliminates the need to drill a pilot hole.
