Nyloc Nut (10894 / 17376)

The Nyloc Nut is a genuine Tacony OEM nylon-insert locknut for the Tornado CK 3030 wide-area vacuum (Model 93030). Tacony changed the part number across the production run, so this listing carries both and you choose by series: 10894 covers Series D, E and F, and 17376 covers Series J. Selecting your series sets the correct part number on the order. It is a genuine Tacony OEM part shared across CleanMax, Powr-Flite and Tornado machines — see the full compatibility list below.

A nylon-insert locknut holds torque where a plain hex nut will not. The nylon collar sits above the threaded portion and is cut by the bolt thread on assembly, so the nut carries a permanent drag that resists the vibration loosening a brush-driven machine generates all day. On the CK 3030 it is used in fastenings where a nut working loose would let a bracket or cover shift under load.

These are wear items in the sense that matters for locknuts: the locking feature is consumed the first time the nut is removed. Any time you take one off for a belt change, a brush-housing strip or a handle repair, fit a new one rather than reusing it. Reusing a spent locknut is the most common reason a fastening that “was tight” is found loose a month later.

Twin City Vacuum has been selling and servicing Tacony equipment since 1956 and stocks the genuine 10894 and 17376 nuts rather than a hardware-store substitute of the same nominal thread.

Frequently Asked Questions

What does the Nyloc Nut do on the Tornado 93030?

A Nyloc nut is a #10-24 hex nut with a nylon insert moulded into the crown. As the nut runs up the thread the nylon deforms around it and grips, so the nut resists backing off under the constant vibration a wide-area brush vacuum produces. On the CK 3030 it is used on the fastenings that must not loosen in service — the ones carrying motor and brush-housing vibration.

Which part number do I need, 10894 or 17376?

Pick by your machine’s series, using the selector on this page. Series D, E and F use 10894. Series J uses 17376. The series letter is on the data label on the machine. They are not interchangeable on paper even though both are #10-24 nylon-insert locknuts — order the one Tacony lists for your series.

How do I know if my Nyloc Nut needs replacing?

Replace it whenever it has been removed. The nylon insert is a one-use locking feature: once the nut has been run off a thread the insert is already formed and it will not grip to the original torque again. Also replace any nut that spins on by hand with no drag, shows a melted or missing nylon crown, or has rounded flats from a slipping wrench.
