27 mm 12-point impact socket
This 27 mm metric socket uses a 1/2 inch drive and a 12-point internal geometry for impact applications. The Grey Pneumatic 2127MD is built for high-torque fastening where standard sockets may round off corners. It suits professional technicians and serious DIYers who need reliable engagement on stubborn metric hardware. The impact-rated construction handles repeated hammer blows without cracking.
Replaces worn or shallow 27 mm sockets
Upgrade when an existing 27 mm socket has stripped points, cracked walls, or lacks the depth for recessed bolts. The 12-point design offers twice the indexing positions of a 6-point equivalent, speeding work in tight clearances. The jump is worth it when fastener access is limited or when impact-gun torque regularly exceeds hand-tool ratings. Keep the old socket only for light, non-impact tasks.
Limited to 1/2 inch drive tools and 27 mm fasteners
This socket fits only 1/2 inch square-drive ratchets, breakers, or impact guns; it will not work with 3/8 inch or 3/4 inch drives without an adapter. The 27 mm hex size matches a single metric bolt or nut diameter, so a full job usually requires additional sizes. The 12-point profile cannot grip rounded or damaged fastener heads as securely as a 6-point socket would.

Questions about this item
Will this 27mm socket fit my 1/2" drive impact wrench?
Yes, the 1/2" drive square matches standard 1/2" impact wrenches and ratchets.
How do I install the socket onto the anvil, and what step is often missed?
Push the socket onto the 1/2" square drive until the detent ball clicks into the retention groove; the missed step is not verifying the click.
When should I replace this 12-point impact socket?
Replace it when the 12-point broach shows rounding, the drive square cracks, or the wall thickness wears thin from repeated impact use.
