Nyloc Nut X8271

The Nyloc Nut X8271 is a genuine Tacony OEM 10-24 nylon-insert lock nut in zinc finish, used across a wide range of Tornado and Powr-Flite commercial cleaning machines. The nylon collar moulded into the top of the nut grips the thread and stops the fastener backing off under the constant vibration a vacuum motor or a brush assembly produces, which is why the factory specifies a locking nut here instead of a plain hex nut.

On the Tornado Pac-Vac Aircomfort backpacks it is used four per machine to secure the harness hardware to the body. On the Prowler and Pro Spotter extractors it appears in the brush and housing assemblies. Because it is a torque-retaining fastener, the nylon insert is a one-use item in practice: once the nut has been run down onto a thread and taken off again the collar has already been cut by the thread and its grip is reduced. Replace the Nyloc Nut X8271 any time you remove one during a repair rather than refitting the old one, and always replace a nut that spins freely by hand down the full thread, that shows a flattened or melted collar, or that has visible thread damage or corrosion on the zinc plating.

Fitting notes

Run the nut down by hand until the thread meets the nylon collar, then finish with a 3/8 inch socket or spanner. Do not use an impact driver — heat from a fast run-down melts the collar and destroys the locking action. Nuts are sold individually; check the quantity your assembly uses before ordering, as the Pac-Vac Aircomfort harness takes four. Twin City Vacuum has been selling and servicing Tornado and Powr-Flite equipment since 1956 and stocks the full Tacony hardware range.

Frequently Asked Questions

What does the Nyloc Nut (part# X8271) do on a Tornado or Powr-Flite machine?

It is a 10-24 nylon-insert locking nut. The nylon collar deforms around the thread as the nut is tightened and holds the clamping load so the fastener cannot vibrate loose — on the Pac-Vac Aircomfort it secures the harness hardware, and on the Prowler and Pro Spotter it is used in the brush and housing assemblies.

How do I know if my Nyloc Nut needs replacing?

Spin it down the thread by hand. A serviceable nut becomes stiff as soon as the thread reaches the collar; one that runs all the way by hand has lost its grip and must be replaced. Also replace any nut with a flattened, glazed or melted collar, damaged threads, or white corrosion on the zinc plating — and replace as a matter of course any nut you removed during a repair.
