KALEI®-PRESSNUTS

KALEI® is a registered TradeMark in most countries for a patent protected Press nut.

The KALEI® – nut is an “impressive” solution if metal sheets starting from a thickness of 1,0 mm have to be provided with threads. KALEI® Press nuts can be used on any metal constructions as well as in connection with a variety of synthetic materials.

The nuts are available in metric threads in sizes from M 2 up to M 20. Specials – with higher collars for use in connection with light metals and synthetic materials or with inch-size threads – can be made available “to order”.

KALEI® – Press nuts are precision products, they are case-hardened and, in their Standard version, are galvanized and blue-passivated. Special surface treatments such as yellow-chromatized, copper-nickel plated, etc. are available “to order”.

The Press nuts are available also in stainless steel (material 1.4305).

kalei1

Centering the nut above the drilled or punched hole. The hole diameter (H 11 accuracy required) must match the smaller diameter of the collar.

The KALEI® Press Nut has been inserted. Its collar, over its full height, is seated in the material. The inclined serration of the collar provides for a save seating of the KALEI® Press Nut.

Screws are always driven from the collar side of the KALEI® Press Nut. When the screw is tightened the KALEI® Press Nut is finally anchored in the material.
Resulting from the proved seat the KALEI® Press Nut is meanwhile used in many industries and processes in which a later correction of the assembly is hardly possible, i.e. in an Air bag assembly. Get in contact!
