Wheel bolt unscrew helper 17, 19, 21 mm & more hex

A simple tool to unscrew your already loose car wheel bolts.

This tool is not for loosening or tightening your wheel bolts, to be clear.

Why would you want such a thing?

After loosening my bolts with a proper tool, I need to turn my crank around 11 times until the bolt is fully out and that’s a hassle.  I would unscrew them with my fingers but my bolts sit relatively deep inside my wheels so that is not an option. 

This tool allows me to unscrew them fast and easy with my fingers (knurled section). If the bolt is a little bit stubborn, I can use the “wings” of the tool to get a bit more leverage.

Same applies to screwing in bolts. I can easily screw them in with my fingers and in the end use a proper tool to fasten them with the right torque.

The tool is available in 17mm hex and 19mm hex. I don’t know what dimensions are used in imperial countries, but if you tell me, I can make a version for that too.

Update 22.10.2025:

Added requested 21 and 22mm versions.

Update 03.02.2026:

Added requested 24 version.

If you have clearance problems, try to scale the model to 100.5-101%

If you find this model useful please leave a comment or maybe a boost. I’m always happy to see photos of my prints from other people.
