KEPS Nut 10892

The KEPS Nut (part# 10892) is a genuine OEM #10-24 hex nut with a captive external-tooth lock washer, used on the Tornado CK 3030 wide-area vacuum (Model 93030) in Series G and J. Fits Tornado 93030, CleanMax CM-WAV and Powr-Flite PF2030. It also fits the Tornado PS Spotter 98220 and the PS8221 98221 and PS8225 98225 professional spotters. It also fits the Tornado PS8226 Spotter 98226, the 230-volt build of the deluxe PS Series spotter.

A KEPS nut is a hex nut assembled with a free-spinning external-tooth washer permanently retained under its bearing face. The washer turns with the nut as it is run down, then its teeth bite into the mating surface as the joint is tightened, giving a locking action and a spread bearing face in a single part. The practical advantage on an assembly line — and in a repair — is that there is one component to handle instead of two, and the washer cannot be dropped or left out.

Because the locking action depends on those teeth biting, a KEPS nut that has been fitted and removed a few times loses effectiveness as the teeth blunt. Replace any nut whose washer has come loose from the nut body or spins with excessive play, whose teeth are visibly rounded, or whose hex flats have been rounded by a slipping wrench. A KEPS nut that can be spun off by hand from a fully tightened joint has stopped locking.

Frequently Asked Questions

What does the KEPS Nut do on the Tornado 93030?

It is the #10-24 nut with a captive toothed lock washer, and the built-in washer spreads the clamping load at the same time.

How is a KEPS nut different from a Nyloc nut?

They lock by different means. A KEPS nut uses a captive toothed washer that bites mechanically into the mating surface; a Nyloc nut uses a nylon insert that grips the thread. The CK 3030 uses both in different positions, so fit the type the manufacturer specifies for the location rather than swapping them.

How do I know if my KEPS Nut needs replacing?

Replace it if the toothed washer has detached or has excessive play, if the teeth are rounded off, if the hex flats are damaged, or if the nut no longer resists being turned by hand once tightened. Fit a new one any time the joint has been apart more than once.
