MAThread®
Lower installation costs thanks to straight screw-in

The innovative ARNOLD MAThread® dog points put an end to costly assembly problems caused by cross-threading of screws into the mating threads. 

Screws with the MAThread® dog point are manufactured in a chipless cold-forming process, they are shorter and lighter than other special fastenings, and they are also very versatile.

MAThread® is used when the screw’s centreline is at an incline to the nut axis – and also in offset assembly, where the screw's centreline has a parallel offset to the centreline of the nut.

MAThread®
compensation thread means no alignment errors

Forget costly assembly problems caused by cross-alignment of screws into the counter threads. When such cross-threading occurs, a new, slanting thread is formed, so the original nut thread is damaged. With our innovative MAThread® dog point, the problem simply goes away, because MAThread® ensures that the screwdriving operation is straight. Screws with the MAThread® dog point are manufactured in a chipless cold-forming process, they are shorter and lighter than other special fastenings, and they are also very versatile. They are robust and easy to fit. With MAThread® you cut out all the problems that commonly occur when fitting threaded fasteners. That's why many OEMs (such as GM, Ford and Daimler) and suppliers (such as Vistoen) are using MAThread®.

With MAThread® Design you can select the dog point for optimum feed into your application.
 

MAThread® matches the thread of the screw with that of the nut, so that the thread does not break out, nor is a second undesired thread produced.
 

MAThread® Design ensures that the two thread spiral align precisely together at every turn of the screwdriver.
