Tornado Strike Screw M3.5 x 16 K73032060

The M3.5 x 16 mm Screw (part# K73032060) is the small fastener the Tornado Strike uses in quantity in its floor tool. It appears in more than one place on the machine — seventeen are called for in the brush head and the same number again where the glide sole assembles — which makes it the one most often lost on a bench.

Compatible Models for the Screw M3.5 x 16

• Tornado Strike Cordless Upright Vacuum — Model TV190-W10-U

This is a Strike-only component: Tacony’s parts records list the Tornado Strike TV190-W10-U as the single machine that takes part# K73032060, so there is no cross-model substitution to worry about when you order it.

What the Screw M3.5 x 16 does

The sole and brush head are the parts of the machine that are opened most often, and every one of those visits cycles these screws. A 3.5 mm screw into a plastic boss has less thread engagement than the bigger body screws, so it is less tolerant of being driven crooked or over-tightened. Getting the right one back in the right hole is also why mixing this screw with the M3 x 6 used elsewhere in the head is a bad idea: the longer screw in a shallow boss will bottom out and split it.

Signs the Screw M3.5 x 16 needs replacing

Replace any that spin without gripping, that have a chewed or rounded recess, or that are visibly bent — a bent small screw has usually been started crooked and has already damaged its boss. Rust on the shank or under the head means the same. If a panel or the sole works loose between services, expect several tired screws rather than one, and change the set.

Fitting the Screw M3.5 x 16

Start each one by hand until it picks up its existing thread, then drive it gently — these are small screws in plastic and they will strip a boss quickly. Do not substitute a longer screw because it feels more secure. Where a row of them holds one component, run them all finger-tight before tightening any fully, working across the pattern so the part pulls down flat.
