A 1/2 inch drive hex bit socket puts allen-key engagement on a ratchet or breaker bar, so a seized socket head cap screw or grub screw gets turned with real leverage instead of a bent L-key.
Each socket is sold individually, so you can replace the size you lost or wore out without buying a full allen socket set. Choose from 11 metric sizes: 5, 6, 7, 8, 9, 10, 12, 14, 16, 17 and 19 mm.
- 1/2 inch square drive hex bit socket with a metric hex (allen) bit
- 11 metric sizes from 5 mm to 19 mm, each sold individually
- For in-hex fasteners, including socket head cap screws and grub screws
- Fits standard 1/2 inch drive ratchets, breaker bars and extensions
