Example for ordering: SCHAAF-article-No. A 4950.12

How to select:
1. The thread size must be covered by the type in consideration, e. g. M 110 x 4 RH requires at least A 4950.11.

2. The Ring Piston must match the counterface. If, in the example of M 110 x 4 RH, the counterface has an ID of 150 mm, the next bigger type of Nut is required, i. e. A 4950.12

3. Please check all relevant dimensions. If they do not fit, ask SCHAAF's consulting service
