Deep (Coarse) The preferred choice for most woodworking applications. Agressive threads maximize holding power in softwoods, particle board, and MDF board.
Type
A Traditional sheet metal thread. Good for multiple applications in wood and metal and commonly used in harder woods to prevent splitting
Twin
Fast Double lead thread decreases drive time compared to single lead thread designs. Good for hardwood fastening applications involving longer length screws.
Hi-Lo Specialty thread originally
designed for plastics used on a small
variety
of wood screw applications.
Machine
Screws Standard machine
screw threads to fit mating part
applica tions such as mounting drawer
pulls.

Screw Features
Nibbed
Flat Head Built-in Nibs under the
head assist the fastener to self-countersink
the screw head without pre-boring.
Type
17 Point The self-drilling point
for wood applications.
Prevents splitting
and bursting
of wood particularly for softwoods,
particle board, and MDF board by
displacing
excess wood material from the drilled
hole.
Sharp
Point Tapered points on deep threaded
screws
for thin material applications
allow fastener to pierce surface
for easy starting.
Spoon
Point Unique drill point for small
screws providing
uniformity in the drilled
wood surface.
Not intended for larger screws where
displacement of wood material is
an issue.
