Wera 344511 3/8" Square to 1/4" Hex Adaptor (Extra Strong)

Fantastic tool for certain small jobs.

This adaptor holds bits very tightly and does a great job when torquing bolts, but it is hard to remove the bits without pushing them from the backside of the adaptor. That makes it time-consuming to change bits frequently, like when working on a mountain bike. I ended up purchasing a Wera 784 B/1 Quick-Release Chuck instead. It makes changing bits very quick and easy.

very well made, very happy with purchase

I really like how time this one hits on both ends, very tite fit. I don't need to buy again because it will Never Break. Thanks KC yes

Bought this so that I could properly torque allen head screws using a torque wrench, while paying less for bits than if I had got a set of sockets. Have done a few services on my car with it without a hitch.

I use it primarily with my M-12 Fuel 3/8" impact wrench. It has held up very well, but I don't use it daily and don't abuse it. It'll extend the utility of any 3/8" square drive ratchet allowing you to use 1/4" hex bits with just one tool! Much lighter than carrying two power tools.
