Metric Nut & Bolt Measuring Tool (M2–M22)
Print Profile(1)

Description
This 3D-printed metric nut and bolt measuring tool is designed for quick and accurate identification of common hardware sizes in the workshop.
The main measuring tool allows you to:
- Determine bolt diameter (M2–M22)
- Measure bolt length up to 150 mm
- Identify nut size for matching metric standards
Two dedicated nut standards are supported:
- ISO 4032
- DIN 934
Separate versions of the main tool are provided for each nut standard. In addition, an auxiliary nut-only measuring tool is available (again in both ISO 4032 and DIN 934 variants). This modular approach allows flexibility—for example, you can print the main tool in DIN 934 and add the ISO 4032 nut tool to cover both standards.
The main tool and the auxiliary nut tool can be joined together using a screw, which is included in the provided print profile, forming a compact and versatile measuring set.
Features
- Metric sizes M2 to M22 (nuts and bolts)
- 150 mm maximum length scale for bolts
- Separate, standard-specific nut gauges (ISO 4032 / DIN 934)
- Modular design with screw-together assembly
- Ideal for workshops, toolboxes, and hardware organization
