Tog-L-Loc® Sheet Metal Clinching System

The fast, low cost assembly alternative to spot welding, rivets, and screws. Manual or automated assembly solutions available.

Tog-L-Loc® (pronounced tog-uhl-lŏk) is a process known as clinching which cold-forms the part metal using a special punch and die to form a strong interlocking clinch joint. The result of the process is a round, button shaped extrusion on the die side of the assembly, and a small cylindrical cavity on the punch side. The clinch joint requires only the sheet metals that were joined. No external fasteners, or welding is utilised in the process.
