These 6" square driver bits (part 56330) drive #3 square screw with a power drill or impact driver. Like the rest of Snappy's bit line, they run on a 1/4" hex power bit shank, so they drop straight into a quick-change chuck alongside your countersinks and drill bit adapters without a separate bit holder.
- Tip: square #3
- Overall length: 6"
- Pack: 2 pcs.
- 1/4" hex power bit shank fits quick-change chucks and impact drivers
- Sold as bits only -- no chuck or holder included
Chuck the tip that matches your screw and drive it home; the 6" length reaches into recessed holes a stubby bit can't.
