1/4" HEX SHANK TO 1/4" SQUARE DRIVE 3" SOCKET ADAPTER
Turn your drill or impact driver into a fast, convenient socket-driving tool with the Benchmark Abrasives 1/4" hex shank to 1/4" square drive socket adapter. The 1/4" quick-change hex shank installs directly into compatible drills and impact drivers, while the 1/4" square-drive end accepts matching sockets for household maintenance, automotive projects, assembly, and general repairs.
Built from industrial-grade, heat-treated S2 tool steel hardened to approximately HRC 60, this adapter is engineered for strength and resistance to shock during demanding fastening work. Precision CNC machining helps maintain accurate dimensions for secure engagement, while the square-drive end is designed to hold the socket firmly during use.

Applications & Performance
Designed for driving fasteners with matching 1/4" square-drive sockets in applications such as:
Household maintenance
General repairs
Automotive and equipment service
Furniture and equipment assembly
Installing and removing nuts and bolts
Light-duty shop and garage work
Projects where powered socket driving improves speed and accessibility
Always select a socket that correctly matches both the adapter's 1/4" square drive and the fastener being driven.
Machine Compatibility
The 1/4" hex shank is designed for compatible impact drivers and rotary drills.
Compatible examples include:
DEWALT® models: DCF850, DCF845, DCF860
Milwaukee® models: 2953-20, 3453-20, 2453-20
Makita® models: XDT20Z, XDT11Z
Bosch® GDR18V-1860C

For keyed or keyless drill chucks, securely clamp the 1/4" hex shank. Use a drill/driver in rotary or screwdriving mode, with hammer mode switched off.
Safety Tips
Always wear appropriate eye and hearing protection during powered fastening operations.
Fully seat the 1/4" hex shank in the tool before use.
Make sure the socket is fully seated on the square-drive end before operating the tool.
Use impact-rated sockets when operating with an impact driver.
Match the socket size to the fastener to reduce slipping and fastener damage.
Do not exceed the operating limits of the drill, driver, socket, or other components in the fastening system.
Inspect the adapter for cracks, deformation, excessive wear, or damage before each use.
Keep hands clear of rotating sockets and fasteners.

Frequently Asked Questions
It allows a drill or impact driver with a compatible 1/4" hex interface to drive sockets that have a 1/4" square-drive opening. The hex shank goes into the tool; the square end holds the socket. It does not attach directly to a square-drive-only impact wrench.
It accepts sockets with a 1/4" female square drive. The actual fastener size is determined by the socket you install on the adapter.
No. The 1/4" measurement refers to the socket's square-drive interface, not the nut or bolt size.
It fits compatible 1/4" hex impact drivers. Compatible examples include: DEWALT® DCF850, DCF845 and DCF860; Milwaukee® 2953-20, 3453-20 and 2453-20; Makita® XDT20Z and XDT11Z; Bosch® GDR18V-1860C; RYOBI® PBLID02; and RIDGID® R862311B. These are examples, not a complete list. It also fits keyed or keyless drill chucks that securely grip a 1/4" shank. Use impact-rated sockets with an impact driver.
It is manufactured from heat-treated S2 tool steel with approximately HRC 60 hardness for strength and shock resistance.
The adapter has an overall length of 3", providing additional reach between the tool and socket.
It is a practical choice for household maintenance, assembly, general repairs and light-duty shop work. Choose equipment rated for the demands of continuous industrial production.
