The first step in the
Tog-L-Loc

process
involves clamping of
the material with a
punch side stripper.

Next, the punch draws
the material into the
die.
As the material flows
into the die, the
die blades expand,
allowing the metal
to flow into a strong
circular interlock.
BTM’s patented Tog-L-Loc
®
sheet metal joining
system is the simple solution for fastening
plain or coated sheet metals. Tog-L-Loc
®
forms
a strong, leakproof joint without welding or
riveting in almost any combination of ductile
sheet metals. The Tog-L-Loc
®
system is widely
used in the manufacture of automobiles,
appliances, furniture, electrical products,
building supplies, and more.

Lance-N-Loc
®
is a sheet metal clinching
system which creates a strong mechanical
joint without the use of external fasteners or
welding. The metals are lanced and squeezed
to form an interlock below the bottom layer of
the sheet metal.
Lance-N-Loc
®
is good for joining harder
materials, multiple layers, and is ideal for use
where electrical conductivity is required.
The final result is a joint with a greater width
than the
drawn section of the metals. This
accounts for the high strength of Lance-N-
Loc
®
joints. The entire sequence takes place
in a single press stroke.
