Clinching Systems


The Tog-L-Loc® round joint from BTM is characterized by its non-cutting joining process. The joining partners are locked together in a circular manner, i.e. over 360°. The round joint is equally firm in all directions in the plane and both sheet metal planes – on the punch and die side – remain tight.


The Lance-N-Loc® rectangular joint is a non-rotating clinching system that is ideal for joining harder materials or even more than two sheet layers. In addition, it is ideally suited when electrical conductivity is to be established on coated sheets, among other things, because it cuts into the sheets locally. This is why it is also called a grounding joint. Different sheet thicknesses can usually even be joined in one tool setting.


The Oval-Loc® clinching joint is a non-rotating clinching system without cutting component. It combines the anti-rotation feature of the Lance-N-Loc® rectangular joint with the non-cutting Tog-L-Loc® clinching joint system.


Multi-Loc® is the term used for multiple clinching tools. Here, 2 or 3 round joint contours are usually combined in one die. The Multi-Loc® clinching tool is the predecessor of the elongated non-cutting Oval-Loc® clinching joint.


The Cavity-Loc® clinching system is a special tool that is used for very hard or brittle materials on the die side. A joining punch presses the ductile punch side joining partner into a pre-punched or hollow area of the second joining partner. The joint can be flush or only slightly raised.


The BTM Fixed-Loc® clinching tool creates a clinching joint using a fixed die engraving. Due to its slim design, the BTM Fixed-Loc® is preferably used on narrow flanges or in installation spaces with only a low installation height. The connection is created by a combination of force and form closure through the back-flow of the joining partners in the die-side ring channel.

Tool Holders & Accessories

Tool holders and accessories are available in a wide variety of designs. The BTM clinching systems are characterised by their modular design, so that the clinching tools can also be exchanged. In addition, different spring forces and punch lengths can be used via exchangeable holding-down systems.
