Why this one
Allen-key engagement with leverage
The hex bit sits on a ratchet or breaker bar, so a seized socket head cap screw or grub screw gets real leverage instead of a bent L-key.
Eleven metric sizes
Sold individually in 5, 6, 7, 8, 9, 10, 12, 14, 16, 17 and 19 mm, so you can replace the size you lost or wore out.
For in-hex fasteners
Suited to socket head cap screws and grub screws that have a hex recess.
1/2 inch drive
Fits standard 1/2 inch drive ratchets, breaker bars and extensions.
Read the full description
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
