SCAT Downloads: Thread Identification
Dimensions of container threads
SCAT safety closures are available for a wide range of different container threads. If you want to use already existing containers, we are providing you an aid in define thread sizes here.
Instructions
Our table for thread identification and helpful overviews of common thread types. We recommend to use a slide gauge and the lower measuring arm to define the outer diameter of the thread Ⓐ or the core diameter of the container opening Ⓑ.
