KNOTT grease nipple screw, M12 x 20 mm GPA 1,2 - 1,5
The KNOTT grease nipple screw is a screw with an integrated grease nipple. It is used to lubricate the bearing in the GPA 1,2 to GPA 1,5 overrun couplings.
Grease is pressed into the bearing point via the nipple using a grease gun. Grease the bearing as part of the overrun coupling's maintenance and clean the nipple head beforehand. Replace a damaged screw only with the same version so that thread and length suit the bearing point.
