Description
The WrenchSizer in stainless steel tells you which wrench or socket fits a nut before you start digging through the toolbox. Imperial on one side, 5/32" to 1-1/2". Metric on the other, 4 mm to 32 mm. Credit-card size.
Two ways to use it
Loose nut: nest it in the "V" and read the size where the farthest corners land.
Nut still on the bolt: set the corner of the nut at the "0" line on the edge scale and read where the flat ends.
If it lands between two lines, use the larger size.
There's a line for every 1/16" and every millimeter, so it doesn't matter which standard the nut was made to. It answers one question: what wrench fits?
Stainless steel, laser engraved. In the package: the WrenchSizer, a vinyl protective sleeve and an instruction card. Made in the USA, U.S. Patent 10,288,400.
Full sizes, specs and FAQ are on the Stainless WrenchSizer page. For technicians, DIYers and shophands on cars, mowers, engines and bikes.
