Product details
This Hoover locking washer, part 013704, holds a fastener in place on commercial Conquest-family uprights so the vibration of daily commercial running does not walk it loose over a long shift. It is confirmed for Hoover C1065 and C1431 commercial models.
A locking washer works by resisting rotation once the fastener is torqued down; serrated or split teeth bite into both the fastener head and the mating surface, so the joint cannot back off under repeated vibration the way it would with a plain flat washer. When those teeth wear flat from age or repeated removal and reinstallation, that grip goes away, and a fastener that used to hold now backs out a little more every shift the machine runs.
On a machine that runs for hours at a stretch, that slow loosening rarely announces itself all at once. It shows up first as a new rattle that was not there before, a wobble in a panel that used to sit tight, or a screw you find sitting loose the next time the housing is opened for another job. Catching it early, before the fastener works its way out entirely, is what keeps a small part from turning into a lost screw and a bigger repair.
- Part: commercial locking washer, part 013704
- Fits: Hoover C1065 and C1431 commercial models
- Function: resists fastener rotation under vibration
- Tip: pair with the correct fastener size for the joint you are servicing, since an undersized washer will not seat against the fastener head correctly
Replace it any time you have a fastener open on one of these machines rather than reusing a flattened washer, since a washer that has already worked loose once rarely regains its original bite. Confirm your model number against the two listed here before ordering.
