Overview
The Klein 66031 comes as a 12-piece set with each piece measuring 3.1 inches and weighing 0.8 ounces, a size and weight far lighter than a standard wrench.
A 0.8 ounce weight per piece is closer to a small screwdriver bit or driver tip than a full-size wrench, so this set likely serves a compact or bit-style role despite the wrench label carried over from the category. Buyers expecting full-length open-end or box wrenches should double check the listing photos, since the dimensions here point to something smaller.

- 12-piece set
- 3.1 inch length per piece
Who it's for
A 12-piece compact set like this fits repetitive small-fastener work where portability matters more than reach. Full-size wrench jobs needing real leverage are better served elsewhere, given the light per-piece weight.
Pros and cons
- 12 pieces in one set
- Compact 3.1 inch length per piece
- High rating (4.8) with strong recent sales (500)
- Piece weight suggests limited leverage versus full-size wrenches
- Fastener size range not stated
- No description to confirm exact use case
Performance notes
12 pieces at 0.8 ounces each keeps the whole set portable, useful for kits or field bags where bulk is a problem. The tradeoff of that light build is reduced leverage compared with full-length wrenches.
