1/4 Square Hole To 1/4 Hex Screwdriver Bit Socket Adapter – 6.3mm Drive

This little adapter lets you use standard 1/4 hex screwdriver bits in tools that have a 1/4 square drive.

Basically, if you've got a socket wrench or something with a square male end, you can pop this on and then use all your regular drill bits or screwdriver tips.

It's a simple, handy tool for anyone who works on stuff around the house or in the garage.

Made in China, unbranded, but it does the job.

Cheap and useful.
