Overview
The Klein 238 is a wrench from Klein Tools, measuring 15.2 centimeters, about six inches, in length, and sold under the Tools > Wrenches category on Amazon.
At roughly six inches, the 238 sits in a mid-size wrench range, longer than Klein's most compact pouch tools but still portable. The listing's item weight figure is inconsistent with a metal wrench of this length, so it has been left out of this summary rather than repeated as fact. A 4.8 star rating from 299 reviews and about 300 units bought in the past month point to consistent demand.
- 15.2 centimeter (about 6 inch) length
- Klein Tools brand, model 238

Who it's for
Fits electricians and tradespeople who want a mid-length wrench from Klein's line for general job site use. Not the right choice for anyone who needs a confirmed jaw size or torque rating, since neither is listed.
Strengths and trade-offs
Drawn from this product's published specifications.
- Mid-length 15.2 cm size for general use
- From an established electrical trade brand
- 4.8 star rating across 299 reviews
- No jaw size or torque rating listed
- Listed weight figure appears unreliable
Performance notes
The 15.2 centimeter length places this wrench between compact pouch tools and full-size bench wrenches, which typically means moderate leverage in a still-portable size. Jaw opening and torque rating are not published, so exact application fit is not confirmed. The listed item weight appears inconsistent with the material and length given, so it is not repeated here as a reliable figure.
