Tornado Tempest Main Skirt Screw M5 x 16 K73031070

The Tornado Tempest main skirt screw (part# K73031070) is the M5 x 16 screw that clamps the skirt plate (part# K50979670) and main skirt (part# K50321810) to the sweeping chamber, with five fitted along the length. Tacony lists it as Screw 5×16, Main Skirt.

Five screws across one plate exist to distribute clamping load evenly, which means all five need to be sound for the skirt to seal. A single stripped or missing screw leaves a slack section, and the skirt lifts there under the air the blower is pulling. It is the cheapest part in the assembly and the one most likely to be quietly responsible for a skirt that is not sealing.

Compatible Models for the Main Skirt Screw M5 x 16

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

When to replace them

• Any screw has a stripped, crossed or galled thread.
• A drive recess is rounded out.
• A screw is missing after a previous service.
• One will not hold torque while its neighbours do.
• The skirt has been renewed — fit fresh screws with it.

Renew the set rather than one screw. They cost very little, they have all done the same work, and a single tired fastener in the middle of five is exactly the fault that is hardest to find afterwards.

Fitting notes

Remove the battery pack before starting. Run all five down finger-tight first, then tighten evenly from the centre outwards so the plate pulls down flat rather than pivoting on one end. Do not overtighten into the mouldings. Check the skirt contacts the floor along its full width before returning the machine to service.

Frequently Asked Questions

What do the main skirt screws do on the Tornado Tempest?

Five of them clamp the skirt plate and main skirt to the sweeping chamber, distributing the clamping load evenly along the skirt so it seals consistently.

How do I know if my skirt screws need replacing?

If any thread is stripped or crossed, a drive recess is rounded, one is missing, or one will not hold torque while the others do. A slack section of skirt usually traces back to a single bad screw.

What models is the main skirt screw (part# K73031070) compatible with?

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

Should I replace all five together?

Yes. They have all done the same work, they cost very little, and one tired screw in the middle of a row is the hardest kind of fault to trace afterwards.
