Choosing a Screw
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.
Deep square drive
improves driver
engagement
and reduces the
possibility of
cam-out.
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.
Self-Tapping
auger point
eliminates the
need to drill
a pilot hole.
Choosing a Screw

of the head to the tip of the screw
