Tornado Nut K73110010

This is the genuine Tacony nut (part# K73110010) used in the rear assembly of the Tornado Strike TV190-W10-U. Three are fitted. The same nut appears on the Tempest and the Zephyr, which is why the title carries the brand rather than a model name. Tacony does not list it in the dealer catalogue, so it is call-for-price.

Compatible Models for the Nut

• Tornado Strike TV190-W10-U cordless upright vacuum
• Tornado Tempest TV400-W26-U cordless upright vacuum
• Tornado Zephyr TV570-Q03-U cordless upright vacuum

This part is shared across Tacony’s cordless range. Its parts records list part# K73110010 against three machines — the Strike TV190-W10-U, the Tempest TV400-W26-U and the Zephyr TV570-Q03-U — so the title carries the brand rather than one model name. Three are fitted to the Strike.

What the Nut does

Fasteners on a commercial machine are specified, not generic. The thread, the head form and the material are all chosen for the joint they sit in and for the tool a technician will have in hand, and a nut of nominally the same size from a hardware drawer may sit differently, clamp differently or corrode where the original would not. On a rear assembly that vibrates all day, those differences matter more than they would on a static fitting.

Signs the Nut needs replacing

Replace any nut that is rounded at the flats, cross-threaded, corroded or has been overtightened past the point where it grips properly. A nut that has been removed and refitted several times is worth replacing as a matter of course when the machine is already open — the cost is negligible and a rounded fastener at the next service is a genuine nuisance.

Fitting the Nut

Start every nut by hand so the thread engages cleanly, then tighten to snug with the correct size tool. Use a new spring or lock washer where the assembly calls for one rather than re-using what came out. Do not over-torque: these joints hold moulded parts, and stripping one costs far more than the fastener.
