As the world’s leading bore gauge manufacturer, Bowers combines decades of metrology expertise with advanced digital technology to offer thread gauging sets, as well as standard and bespoke thread gauging solutions tailored to your application.

The trigger action pistol-grip controller enables the operator to retract the anvils instantly and pass the gauge through the entry diameter, then extend the anvils to engage with the thread diameter for an immediate absolute measurement.

Modular & Adaptable

The Bowers XT range is highly adaptable. Once you have our Digital Pistol Grip Bore Gauge, you can use multiple heads with ease. Fit them interchangeably to our Bluetooth XT range of Digital Controllers in seconds for fast, efficient use with incredibly accurate results! Other heads are also available for grooves, splines, slots, deep hole and many more applications.

Why choose Bowers thread gauging over hard gauging?

Compared to traditional hard gauging, Bowers thread gauging solutions provide faster measurement without the need to screw gauges in and out, significantly improving productivity. Machinists benefit from immediate, accurate size feedback during thread forming, reducing repeat cuts, minimising errors, and saving machining time. With fewer gauges required, calibration costs are also reduced, making Bowers thread gauging a smarter, more cost-effective solution for modern manufacturing.
