When you think of pocket hole join-
ery you probably associate it with
mass-produced kitchen cabinets and
furniture. The kind that are easy to
build and fast to assemble.
But this type of joinery is not just
for making face frames for cabinets.
And you don’t have to work in a
cabinet shop to use it. Because it’s so
quick and easy (see box below), I find
myself relying on it more and more.
Pocket hole joinery works well for
almost any joint. Here are a few ways
I’ve found to get the most out of it.
corner JointS.
Pocket holes are great for
joining corners, like attaching aprons to
table legs. Pocket holes are faster and
easier to use than cutting mortise and
tenon joints. And with a little bit of rein-
forcement from a corner block, they’re
every bit as strong. You can see what I
mean in the photo above.
Just use the jig to guide your drill
and place two pocket holes at the end
of each apron. Then choose the right
pocket screw for the job (see the hard-
ware box on the next page) and secure
the apron to the leg.

Drilling Pocket Holes.
The pocket hole jig guides the drill bit at
exactly the correct angle. The stop collar can easily be set to accu-
rately drill the correct depth hole in various thicknesses of wood.
Inserting Pocket Hole Screws.
After the
hole has been drilled, it's easy to drive the
self-tapping pocket hole screws in place.

Joint reinforcement.
As I mentioned, it
doesn’t hurt to reinforce table legs with
a corner block as shown in the photo on
the opposite page. It’s attached with three
pocket hole screws. One screw is driven
into each apron and one into the leg. This
adds even more strength and stability to
the legs at each of the corners.
miter JointS.
Pocket hole joinery can
come in real handy when you need to pull
a miter joint together. To hold a miter joint
tight, drill a pair of pocket holes oppo-
site and perpendicular to the joint line,
as shown in the photo at the right. A face
clamp holds the joint flush while you
drive in the screws.
AttAch A tAble top.
You don’t usually
think of using pocket screws for attach-
ing the top of a table. But it’s as easy as
drilling holes into the aprons (see photo
below) and then driving screws into the
table top. Using the jig and the correct
screw size insures that the screws don’t
come through the top of the table.
If you’re concerned about wood move-
ment, drill the pilot holes in the edge a lit-
tle oversized. Then after driving the screw,

back it out one quarter turn so it can move
as temperature or humidity changes.
Shelf edging.
Adding shelf edging to ply-
wood with pocket holes is another of my
favorite applications. It beats gluing and
clamping each piece of edging in place.
Of course, the edging needs to be thick
enough to receive the screw.
Simply drill pocket holes on the under-
side of the shelf along the edge like you
see in the photo below, right. Then drive
in the pocket hole screws to fasten the
shelf edging securely in place. You can
add a bit of glue as well.
The right angle clamp shown in the
photo helps out here. One arm fits into
the pocket hole and the flat surface on the
other arm holds the edging in place so you
can drive in the pocket screws.
As you can see, pocket hole joinery
has many uses. The joints are strong and
they look great. You’ll be surprised at how
many uses you come up with in your own
shop for this quick and easy joinery.

Attach a table top by drilling pocket holes and driving
screws. Drilling the pilot hole a bit larger and backing
the screw out slightly, allows for wood movement.

Pocket holes are a great way to secure edging to a
shelf. A right-angle clamp holds the edging to the shelf
while the screws are driven in place.
Hardware:

Thread Type.
Fine threads (top) are
used for hardwood and course threads
are for softwoods and plywood
.
{
Screw Length.
Screws are available in many
sizes so you can match the screw length to the
thickness of the workpieces.
{
Head Style.
Use washer head screws (top)
for plywood and softwoods. Pan head
screws (bottom) are for hardwoods.
