Screw punching die Lance-N-Loc®

BTM Lance-N-Loc® Stepped Short Insert (SSI) 940 Series Dies feature a built in die shield that surrounds an elastomeric ring and two die blades. 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.
