TDN wrote in with a tip about Channellock’s Uni-Fit 34-in-2 wrench set. He spotted them at a Walmart store in Canada, but they’re available in the USA as well.
Channellock Uni-Fit tools feature universal spline heads that fit both inch and metric fasteners.
There are a couple of different Uni-Fit products:
A 2-piece “34-in-2” ratcheting wrench set.
A 6-piece ratcheting wrench set.
A 24-piece 1/4″ and 3/8″ ratchet and socket set.
Each set is priced at $30-$35 via Amazon.

The benefit of universal spline wrenches and sockets is that you can work with more fastener sizes with fewer tools.
However, tools that combine inch and metric sizes don’t often fit fasteners as well as single-size tools. That is, a 5/8″ and 16mm socket won’t fit 5/8″ and 16mm fasteners as well as separate 5/8″ and 16mm sockets will. For that reason, I tend to shy away from these types of universal tools.
Just because Channellock put their name on these tools isn’t enough to change my feelings towards universal tools. These are made in Taiwan for Channellock, and you could probably find the tools under other brands’ labels as well.
These tools allow you to pack a lot of functionality into portable tool kits, but keep in mind the tradeoff. You save on weight, size, and cost, but give up the precise fitment that some fasteners and applications demand.
