Product details
This is a small replacement nut sized for Hoover's 1100 Dial-A-Matic upright, also listed against the Hoover 6428. Order it as part 12079.
This Dial-A-Matic dates to an earlier generation of Hoover engineering, and the hardware holding it together was not something you could grab off a generic hardware store rack and expect to match. Fastener threads, head sizes and finishes on machines from this era were often specific to the model, which makes sourcing the correct original-pattern nut the trickiest part of keeping one of these uprights running, more so than the repair itself.
When this nut goes missing or its threads strip out, whatever it was securing comes loose, and loose hardware on a machine this old accelerates wear everywhere nearby: rattling, play at the joint, and eventually enough movement that the part shifts out of position. Fitting the correct replacement restores a tight, rattle-free assembly, and installation only calls for basic hand tools, no drilling or thread-cutting to force an off-the-shelf fastener into a spot it was never meant for.
- Part: 12079
- Fits: Hoover 1100 Dial-A-Matic, Hoover 6428
- Function: hardware fastener, original thread pattern
- Symptom: rattling or play at the joint it secures
Owners keeping a Dial-A-Matic running tend to find that stocking the right small hardware, instead of substituting a generic nut, makes the next repair go faster too, since a mismatched thread pitch strips out even sooner than the part it replaced. Confirm the model stamped on your machine before ordering.
