Schnorr Type S serrated safety washer in a black finish: 3 items, sizes M8, M10 and M36, supplied as packs of 10 to 200.

Schnorr describes its serrated safety washers as conical, with precision serrations, built on the basic principle of a disc spring (manufacturer-stated).

Schnorr gives the hardness of its safety washers as 39 to 45 HRC (manufacturer-stated). Schnorr describes its original safety washers as having high resistance to vibration (manufacturer-stated).

Each item shows its size and its listed dimensions, for example M8 x 13 x 0.7mm. Only the size is labelled; the other figures are printed in the item name without labels, so this page does not say which is the outer diameter or the thickness.

Schnorr makes safety washers and disc springs for the automotive or aerospace industry and machine construction (manufacturer-stated).

Selecting the right option

Choose the Type, size and finish together. Check the listed dimensions against your joint, because the figures are printed without labels.

The same Type is also listed in a different finish (the zinc plated version); for the other Type in the same finish see the Type VS page.
