Robert Sorby Thread & Sizing Gauge

Product Description

Thread & Sizing Gauge (H973000)

• 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 tip most commonly used by thread cutters.
• The gauge has a built-in compensation factor to ensure a perfect thread between internal and external diameters every time.
