Robert Sorby 973 Thread & Sizing Gauge

$57.00

Stock: Available

Product Code: 19-228

Ideal for box-makers, this gauge takes all the guess-work out of fitting the major and minor diameters of pieces.

With the gauge set at the unmarked anvil this creates a 1:1 correlation between the measuring faces and facilitates accurate push fits.

The other three anvils are marked 10, 16 and 20 which relates to the tpi most commonly used by thread cutters.

The gauge has a built-in compensation factor to ensure a perfect, tight thread fit between internal and external diameters every time.
