Overview
Weighing 2.4 ounces and measuring 7.75 inches, the Klein 612-4 is a single flat-tip screwdriver, a light, single-piece driver from Klein Tools rather than a multi-bit set.
Klein's 600 series screwdrivers are built around a fixed shank and tip sold individually by length and tip type rather than bundled as kits. The 612-4 follows that pattern, a standalone driver sized for electrical and general trade work rather than a boxed set.
- 7.75 inch overall length
- 2.4 ounce weight
- Sold as a single screwdriver
- 4.8 average rating
Who it's for
Electricians and tradespeople who want a single, well-made flat screwdriver to add to a pouch or an existing set. Not for anyone shopping for a multi-bit or ratcheting screwdriver kit.
Strengths and trade-offs
Drawn from this product's published specifications.
- Light enough for pouch or pocket carry
- Klein Tools build quality
- Rated 4.8 stars across 2200 plus reviews
- Single fixed tip, not a multi-bit driver
- Sold as one piece, not a set
Performance notes
At under 2.5 ounces and under 8 inches long, this is a driver built for control in tight spots rather than maximum torque, the tradeoff most single fixed-shank screwdrivers make in exchange for a slim profile.
