3/8 Drive Deep Duo-Socket for Mechanics
This Grey Pneumatic 81018D socket fits a 3/8 inch drive and a 9/16 inch fastener with a six-point profile. The deep design reaches recessed bolts common in automotive repair. Professional technicians and home garage owners gain a single tool for this specific size combination.
Hand-Tool Operation Requires No Power
As a manual socket it produces no heat, noise or electrical draw during use. Performance depends on the ratchet or breaker bar applied by the operator. There are no thermal limits, fan curves or power-supply requirements to consider.
Six-Point Geometry Protects Fasteners
The six-point opening grips the flats of a 9/16 inch bolt or nut rather than the corners. This reduces rounding risk when high torque is needed. No additional accessories or software are included with the socket.

Questions about this item
How do you fit the 81018 deep duo-socket onto a 3/8 drive ratchet, and what step do people miss?
Align the 6-point opening with the fastener, press the socket squarely onto the ratchet anvil until the detent ball clicks, then verify it is fully seated before applying torque — the missed step is skipping that click check.
What upkeep will the 81018 deep duo-socket need over time?
Wipe the 6-point faces clean after each use, apply a light coat of machine oil to prevent rust, and inspect the drive square for rounding; replace the socket if the walls show cracks or the detent no longer holds.
What limit appears first when the 81018 deep duo-socket sees heavy, repeated torque?
The 6-point socket walls will deform or the drive-square corners will round before the detent fails, signalling the tool has reached its practical torque ceiling.
