Lance-N-Loc is a sheet metal clinching system which creates a strong mechanical joint by lancing the 2 long sides of the joint and gradually drawing the ends. The material on the sides of the joint is compressed and interlocked, while the gradually sloping ends allow harder materials to be joined making higher strength joints, all in a single press stroke.

BTM's Lance-N-Loc Ball Lock Punch Holder Assemblies provide a simple means of mounting the Lance-N-Loc Punch and Stripper package when the tooling is to be mounted in a die set (or similar application). The overall length of the Punch Holder Assembly may be specified (four standard lengths) based on part clearance requirements.
