Tornado Tempest Baffle Plate Nut M6 K73114250

The Tornado Tempest baffle plate nut (part# K73114250) is the M6 hex nut retaining the brushroll end plate screws on the TV400-W26-U cordless sweeper, with three fitted. Tacony lists it as nut M6-04, Adjustment, and its own record gives the specification as HEX NUT M6 04 A2E ISO 10511.

ISO 10511 is the standard for prevailing-torque hex nuts with a non-metallic insert — a nylon-insert lock nut. That matters on this joint. The brushroll assembly vibrates continuously while the machine runs, and a plain nut on a three-screw plate would walk loose in service. The insert is what stops that, and it is also why these are single-use: once the nylon has been cut by the thread, a re-used nut no longer locks.

Compatible Models for the Baffle Plate Nut M6

• Tornado Tempest Wide-Area Cordless Carpet Vacuum Sweeper — Model TV400-W26-U

When to replace it

• Any time it has been removed — the nylon insert is single-use.
• The nut can be run down the thread by hand with no resistance.
• The thread is stripped, crossed or galled.
• The flats are rounded so it cannot be held properly.
• It has been found loose in service.

The first point is the one most often ignored and the most consequential here. A re-used lock nut on a vibrating brushroll assembly is a fastener waiting to come off.

Fitting notes

Remove the battery pack before starting. The nuts pair with the M6 x 35 screws (part# K73061180) through the brushroll end plates. You should feel real resistance as the thread reaches the nylon — if it runs on freely, the nut is spent. Tighten all three evenly so the plate pulls up square.

Frequently Asked Questions

What does this nut do on the Tornado Tempest?

It retains the brushroll end plate screws. It is a nylon-insert lock nut to ISO 10511, which stops it walking loose against the continuous vibration of the brushroll assembly.

How do I know if it needs replacing?

If it runs down the thread by hand with no resistance, the nylon insert is spent. Also replace it if the thread is damaged, the flats are rounded, or it has been found loose — and always after removal.

What models is this nut (part# K73114250) compatible with?

The Tornado Tempest TV400-W26-U wide-area cordless carpet sweeper. PartSmart lists it against the Tempest alone, and three are fitted per machine.

Can I reuse the nuts?

No. The nylon insert is cut by the thread the first time it is fitted, so a re-used nut no longer locks. On a continuously vibrating brushroll assembly that is a fastener waiting to come off.
