Key specifications
Brand: GEKO
Model / MPN: 7139109
EAN: 5901477139109
Quantity: 24 leaves
Thread size range: 0.25 mm – 6 mm
How to use
Select a leaf that corresponds to the estimated thread pitch and engage it with the thread to be measured; a correct fit indicates the matching size. For external threads place the leaf into the thread profile, and for internal threads insert the leaf to check engagement. Compare several adjacent leaves if necessary to confirm the best fit, then read the marked size on the leaf.
Usage recommendations
Store the leaves in their case to prevent damage and keep surfaces clean. Use the gauge in dry conditions and avoid excessive force when fitting leaves to threads to prevent deforming the sample or the gauge.
