Lance-N-Loc® Sheet Metal Joining System

Lance-N-Loc® Punch & die

BTM’s Lance-N-Loc® Joining System produces clean, strong and consistent joints in most coated or uncoated metals. The joints are characterized by a “button” formed on the die side layer of metal and a recess formed in the punch side layer. The button is a good indicator of joint quality and therefore, simplifies quality control. Two or more layers of metal typically ranging in thickness from .008" (0.2mm) to .157" (4.0mm) per sheet can be reliably joined in most cases.

Lance-N-Loc® Cross Section

Lance-N-Loc® is used in the automotive, appliance, heating & cooling, office furniture, garage door, computer and various other industries.

Lance-N-Loc® is commonly used where metals are insufficiently ductile to join using Tog-L-Loc® or in certain dissimilar combinations or multiple layers.
