What to know before buying

Listing details to confirm

The listing is inconsistent about the kit contents: a feature claim describes eight spanners plus a bolt gauge and mentions a storage rack, while the explicit contents list names only a ratchet spanner. The gauge and rack inclusion are unconfirmed, so check the selected listing before purchase. The 72-tooth and 5° figures are listing claims.

Frequently asked questions

Which spanner sizes are listed?

The listing names 8, 10, 12, 13, 14, 15, 17 and 19 mm sizes.

Does the set include a bolt gauge and storage rack?

Their inclusion is uncertain. A feature claim mentions a bolt gauge and storage rack, but the explicit contents list names only a ratchet spanner.

What does the 72-tooth claim mean for use?

The listing pairs the 72-tooth ratchet with a claimed 5° working angle, intended to allow smaller handle movements between turns. This is a listing claim, not an independently verified performance result.
