Zyklop 8784 A1 Adaptor, Hexagon drive 1/4" Head x 37mm Adaptor,5003529001

Got this as an adapter between 1/4" square torque wrench and 1/4" hex bits. I tried some less expensive adapters, and the 1/4" square side would drop off the wrench -- not good when tightening a breaker screw in a live panel. Spend the extra few dollars and get something that won't cause you any frustration or hurt. Removing it from the plastic hanger requires more effort than it should.

Holds bits well, easy to attach/detach

Wera quality as always.

This fits the Zyklop 8000 A 1/4-inch Drive Ratchet perfectly. I wish it was clear on the Drive Ratchet what adapter you need, hence the 4 star review. But this is the adapter you need. This works perfectly with the screw bits in the Tool Check Plus. For an adapter, it's a little pricey but its utility is amazing and really gives the Drive Ratchet new functionality.

These bit adapters are considered wearables but it’s one of my most used tools, holds up great.

Hex bits wont fall out or get stuck in bolt heads, the collar really retains your bits.

This review is for the Wera Zyklop 1/4 square drive to 1/4 hex bit adaptor. Typical Wera quality. It would be nice if Wera could come up with this adaptor using the Rapidaptor technology but this will do. I can live with having to slide the collar to install and remove bits. While this adaptor is designed for use with one inch insert bits with the notches (and it does so very well) it will lock in two inch and longer power drive bits with some slop which is usable with hand tools, the primary application for this bit adaptor. This adaptor is not designed for impact use. I am using this adaptor with a quarter inch drive ratchet and torque wrenches. There is no magnet in this holder so if you need that you will want a magnetized bit. Overall I am happy with this adaptor.

works great - use for bits with my zyklops
