Threadmaster Pro – Universal Thread Gauge

The Threadmaster Pro is a compact, multi-functional measuring tool designed and 3D-printed to provide mechanics and machinists with a complete solution in one pocket-sized device.

Main Functions:

1. Bolt length measurement – the built-in ruler (0–100 mm) allows quick and easy measurement of bolt length.

2. Metal type detection with magnet – an optional magnet can be added to identify whether a bolt is made of regular steel or stainless steel. In the field, this is especially useful for selecting the correct welding electrode.

3. Thread identification – the gauge supports the following thread standards:

Metric (M)

Inch (UNC/UNF)

BSP
Identification is done by inserting the bolt into the matching slots on the gauge.

4. Matching spanner sizes – on the back of the booklet, the corresponding spanner size for each bolt is indicated.

5. Keyway slot measurement – dedicated gauges allow checking the size of keyways in couplings, gears, and shafts.

6. 90° folding design – the gauge can be opened to a 90° angle and used as a machinist’s square for checking right angles.

7. Key size verification using pass-through slots – special slots in the gauge allow passing the key through to identify its exact size.

Key Advantages:

Combines multiple essential measuring tools into one device.

Compact, portable, and easy to carry.

Tested and proven in real workshop conditions.

Suitable for mechanics, machinists, welders, CNC operators, and DIY enthusiasts.
