Tog-L-LocTog-L-Loc® is sheet metal joining or “clinching” made simple. Fast, economical and consistent, the Tog-L-Loc sheet metal joining system is an alternative to spot welding and riveting, and is used worldwide to assemble automobile parts, appliances and more. Whether joining plain, painted or coated sheet metal parts with BTM’s patented Tog-L-Loc® sheet metal joining technique, there are no fasteners, sparks, or fumes. From simple tooling to high speed automation, BTM provides solutions for your sheet metal assembly requirements.

Lance-N-LocLance-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.

Riv-LocRiv-Loc is an alternative to welding and traditional riveting. The Riv-Loc process utilizes a self-piercing fastener in a simple punch and die operation to automatically feed, punch, insert, and lock the fastener into place- all in a single high-cycle operation.

The Riv-Loc process is ideal when joining a range of materials including pre-painted, pre-coated, and dissimilar metal combinations, including varying thicknesses.

BTM offers production equipment to utilize the Riv-Loc process ranging from single-hit machines to fully automated turn-key systems.
