Grease Cup - Brass Size:5-40 thread height: 7/16" rim diameter: 1/4" These grease cups are scaledThese grease cups are scaled down version of those widely used on all machinery in the age of steam to apply grease under pressure to a bearing. They work just like the original: put grease in the cap, screw down on the body and grease is applied under pressure to the bearing. They have knurled tops and do a great job of adding the additional detail to dress up an engine.
