Our stainless-steel winches are adapted at the gallows by a rivet method to be precise with a blind-rivet-screw-nut.

What is a blind-rivet method?

The insertion by blind-rivets is made from only one side of the component. The blind-rivet is inserted through a hole in the component and by single sided pressure both components get connected. Afterwards the rivet’s mandrel is pulled out with a blind-rivet-tong. This process leads to a compression and enlarges the rivet behind the component’s hole. 


Blind-rivet-screw-nuts and blind-rivet-screw are the best way to provide components with little wall thickness with a thread. Blind-rivet-screw-nuts are sleeves with an inner thread on one side and a cuff on the opposite side. The shaft has a thin wall between cuff and thread. As setting toll screws or thread bolts are screwed in this creates by tightening the bolt a bulge in the shaft and attaches the blind-rivet-screw-nut with the substrate.


Why do we use a blind-rivet method here?

To drill a thread in to a material with thin walls can always have the disadvantage of quick wear.

Of cause it is advantageous to use a so called “external thread” (Blind-rivet-screw-nut) by working with thin walled material. Especially for the owner it is very comfortable if it is able to tight up the screw if it has loosened itself through external influences or ruff usage.
