What to know before buying

Listing details to confirm

The title claims the set comes with a case, but the explicit manufacturer contents list names only the 20 wrenches and does not confirm a case. Check the selected listing before purchase. The same list specifies metric sizes from 6mm through 18mm with gaps, and SAE sizes from 1/4" through 3/4" with listed increments, so verify coverage for your fasteners. The displayed dimensions, weight and finish are listing details, not independent measurements.

What’s in the box

10 SAE ratcheting wrenches: 1/4", 5/16", 11/32", 3/8", 7/16", 1/2", 9/16", 5/8", 11/16", 3/4"Included
10 metric ratcheting wrenches: 6mm, 8mm, 10mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mmIncluded

Frequently asked questions

What sizes are listed in the set?

The supplied contents list names 10 SAE sizes from 1/4" to 3/4" and 10 metric sizes from 6mm to 18mm. The metric list skips some sizes, so compare it with the fasteners you use.

Is the case included?

The title says the set comes with a case, but the explicit contents list names only the wrenches. Case inclusion is therefore uncertain, so confirm it in the selected listing.

What does the 4-degree arc swing refer to?

The listing describes the 90-tooth ratcheting box end as having a 4-degree arc swing, a feature intended to allow smaller handle movements in confined spaces.

Does the set have a warranty?

The listing claims a full lifetime warranty. Review the applicable warranty terms for coverage and conditions.
