Kreg offers a complete line of pocket screws for every workpiece thickness and type. Use this chart to
select the correct screw length. All Kreg pocket screws are available at your Kreg dealer or online at
kregtool.com.
Position the Stop Collar
Place the step bit in the setup gauge on the jig base,
aligning the step shoulder with the dimension mark that
matches the thickness of your workpiece. Slide the stop
collar onto the end of the bit and position it against the end
of the stop-collar recess. Tighten the stop-collar set screw
with the hex wrench.
3
Adjust the Clamp Pad
Advance the toggle clamp to the full-clamped position.
Place your workpiece against the drill guide, loosen the
jam nut on the clamp-pad shaft, and finger-tighten the
clamp pad against the workpiece. Unclamp the toggle and
advance the clamp pad 1½ to 2 turns. Test for adequate
clamp pressure, make any necessary adjustment, and
tighten the jam nut.
