workpiece size and type. Use this graph to fi nd the correct
screw. All are available online, at www.kregjig.com or at

Fine Thread

Fine thread screws are
recommended for hardwoods as
they reduce the chance of the
material splitting when driven.

Coarse Thread

Due to a signifi cantly larger
thread diameter, coarse thread
screws offer a much stronger
hold in composite materials such
as MDF and plywood.

Self-Tapping

Auger point

eliminates the

need to drill a

pilot hole.

Deep Square Drive

improves driver

engagement and

reduces the

possibility of

cam-out.
