Using the Kreg Jig
To create strong joints, you'll set your jig to match the
thickness of the workpiece and the length of the screw.
The Kreg Jig
®
makes this easy, in just four simple steps:
1
Set the Drill Guide
For a strong joint, the screw should exit close to the centre
of the drilled workpiece. To adjust the pocket-hole position,
unscrew the drill-guide locking pin. Then align the mark on
the side of the drill guide that matches the thickness of the
workpiece with the top edge of the guide socket. Screw in
the locking pin.
2
Choose a Screw
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 • Particle Board
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.

Fine Thread
Because the smaller diameter and thread
pitch of 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 • Birch
