KOELNER High tensil structural washers MoS2 lubricated

Catalog no.: 2819
7 variants
Note: Calibration as supplied applies to tightening by turning the nut. If tightening is carried out on the head side with a correspondingly molycotised washer, calibration must be carried out in accordance with Annex H of DIN EN 1090-2 or by means of supplementary tests in accordance with EN 14399-2. These procedure tests are already carried out by the manufacturer. The end user therefore no longer has to carry out any procedure tests and the tightening procedures and their parameters remain identical to those of the tightening on the nut side.
