Overview
Klein's 630-1/4M is a flat-blade screwdriver sized to a quarter-inch tip, from a brand known for electrician-grade hand tools. It carries a 4.7 rating across 1,868 reviews, with about 100 bought in the past month.
Klein Tools built its reputation on hand tools for electricians and tradespeople, and the 630 series is part of that lineup rather than a general hardware-store screwdriver. Amazon lists no additional spec sheet or seller copy for this listing, so what stands out is the sales history rather than a features list. A 1/4 inch slotted tip points to general-purpose use on standard slotted screws rather than precision electronics work.
- Slotted 1/4 inch tip
- Klein Tools brand

Who it's for
Fits anyone who wants a single reliable slotted screwdriver from a trade-tool brand rather than a boxed multi-bit set. Less useful for someone who mainly needs Phillips or Torx drivers, since this is a flat-blade tool.
