Hi, I'm Steve Smith with Camper Van Freedom. This is my DEWALT folding metric hex-key set. I own several folding metric tools, but this is the one I reach for first when I see it. It is another of my favorite DEWALT tools. On my roof assembly, an Allen key also helped position the small slot nuts. The matching product picture shows the keys retained in a folding handle. An individual key rotates out for work at the fastener. Keeping the keys together changes how I carry and handle the set compared with separate L-shaped keys. The handle shape also matters when there is little room beside a joint. My roof-assembly photographs show small bolts, slot hardware and an angle connection. The rack used quarter-twenty hardware, while my added twenty-twenty extrusion used M five hardware. These were different hardware systems meeting in the assembly. The workshop footage illustrates measuring and holding work. The small nuts moved and spun while I tried to start the bolts. I used the thin bars of an Allen key to fish them into position inside the extrusion. Positioning the nut came before getting the bolt started. The diagram separates the slot, the moving nut and the approaching bolt. My owner review is straightforward: this DEWALT is the folding metric tool I reach for first. That preference sits alongside the practical assembly story. A compact hand tool helped with a fiddly positioning job after the larger cutting and drilling tasks were already behind me. The close-up photographs show the connection rather than a cutaway of the channel. Moving the nut, lining up the opening and starting the bolt were separate parts of fitting the joint. The small hand tool's reach mattered here, as did the room occupied by its handle. My page compares two researched alternatives. Bondhus one zero nine nine nine supplies separate L-shaped metric keys with ball ends. Klein seven zero five eight two keeps metric keys together in a folding handle. Their matching pictures show the two arrangements. My own preference in this review is the DEWALT I used. Thanks for watching. I'm Steve Smith with Camper Van Freedom. This was my DEWALT metric hex-key review and the small-nut alignment problem behind my roof connection. The full review, build photographs and current buying options are linked below. Until next time.
