Drive adapter for 1/4 in hex to 3/8 in square
This Apex EX-370-4 power drive adapter converts a 1/4 inch hex male input to a 3/8 inch square male output. It suits technicians who need to drive square-drive sockets with a hex-shank power tool. The 4 inch overall length provides reach in confined spaces. The tool is new and non-sparking is not rated.
Installation and common issues
Insert the hex shank into a compatible power tool chuck until it seats firmly, then attach the required 3/8 inch square-drive socket. The adapter transmits torque directly, so ensure the tool’s clutch or torque limiter is set correctly to avoid over-tightening. A worn or rounded hex shank can slip under load, damaging the chuck or fastener. Always verify the socket is fully engaged before applying power.
1/4 in hex to 3/8 in square conversion
The defining specification is the drive conversion: a 1/4 inch hex male input to a 3/8 inch square male output. This determines whether the adapter fits your power tool and accepts your sockets. No other size or drive combination is supported by this part.

Questions about this item
How can I confirm the 1/4-inch hex input drive engages securely with my power tool?
Insert the hex shank fully into the chuck or bit holder until it seats; the 4-inch overall length lets you feel positive engagement before applying torque.
What comes in the package and do I need a separate 3/8-inch square-drive socket?
The box contains one power drive adapter with a 1/4-inch hex male input and a 3/8-inch square male output; any 3/8-inch drive sockets required for the job must be purchased separately.
Which version should I choose if I need a 1/4-inch hex to 3/8-inch square power adapter?
The EX-370-4 is the single model offered with that exact drive conversion and a 4-inch overall length, so select it when those specifications match your application.
