Tornado Tempest Hinge Screw M5 x 35 K73031100

The Tornado Tempest hinge screw (part# K73031100) is the M5 x 35 screw at the main cover hinge pivots on the TV400-W26-U cordless sweeper, with four fitted. Tacony lists it as Screw 5×35, Hinge. At 35mm it is the longest M5 on the machine, and the length is the whole point: it has to pass through the swivel arm, its washers and the mounting to form the pivot.

Because it is acting as a pivot pin rather than purely as a fastener, its shank condition matters as much as its thread. A scored or bent shank makes the hinge stiff or notchy, and a hinge that does not swing freely puts the cover down out of square — which then shows up as a suction complaint rather than as a hinge complaint.

Compatible Models for the Hinge Screw M5 x 35

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

When to replace it

• The drive recess is rounded out.
• The hinge is stiff or notchy through its travel.
• The hinges or their washers are being renewed.

Fitting notes

Remove the battery pack before starting. Each screw passes through the swivel arm (part# K50356100) and its washers (part# K73122820). Do not substitute a shorter M5 — anything less than 35mm will not carry the pivot properly even if it threads in. Tighten enough to retain without clamping the hinge solid; the cover must swing freely. Check it lands square and the gasket compresses evenly before returning the machine to service.

Frequently Asked Questions

What does the hinge screw do on the Tornado Tempest?

It passes through the swivel arm and its washers to form the main cover hinge pivot, acting as a pivot pin as much as a fastener.

How do I know if my hinge screw needs replacing?

If the shank is scored, worn or bent, the thread is damaged, the drive recess is rounded, or the hinge is stiff and notchy through its travel.

What models is the hinge screw (part# K73031100) compatible with?

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

Can I use a shorter M5 screw here?

No. At 35mm this is the longest M5 on the machine because it has to pass through the swivel arm, washers and mounting to form the pivot. A shorter screw will thread in but will not carry the hinge.
