Cutting-edge Nail TechnologyDOUB LOCK NAILⓇ

DS NailⓇ

Drivable Screw Nails (PAT)

Harness the strength of a self-rotating screw,
while using a nail gun to drive it in place.
Can also be removed like a screw.Drivable Screw Nails

Exerts the same fastening force as
a screw and can be inserted
with a nail gun.

Unlike conventional screw nails,
the entire nail is embedded in the material when driven in.
This allows you to utilize the full strength
of the nail without creating open space between materials.
