Tornado Nylon Screw #6-32 x 3/4″ 19124

A nylon screw is used where a metal one would cause a problem rather than solve one: it does not conduct, it does not corrode, and it will not seize into a plastic boss. Part number 19124 is the genuine OEM nylon slotted round head machine screw, #6-32 by 3/4 inch. It also fits the Tornado 98167 20″ Marathon 800 carpet extractor (8 Gallon, 230V).

Being non-conductive is often the actual reason it is there. A nylon screw near a terminal, a board or a switch cannot create a path to anything, and substituting a steel screw in such a position can turn a harmless fixing into a live one. That alone is reason enough not to reach for the metal equivalent because it is closer to hand.

The slotted head is worth a word. A slot is the weakest drive there is and a nylon slot is weaker still, so a driver that is too narrow will tear the slot out on the first firm turn. Use a blade that fills the slot across its full width and depth, and keep it square — nylon gives no second chance.

#6-32 is a small thread with very little material in it. In nylon that means the strip torque is low, and low means finger-firm. If the screw does not feel tight at that point, look for the reason rather than applying more force: a washer missing, a face not flat, or a hole that has already been damaged by an earlier over-tightening.

Treat it as single use in any position that matters. The thread deforms on every tightening and a nylon screw that has been in and out three times no longer holds. It costs almost nothing.

Watch for heat and chemistry. Nylon near a warm component embrittles over time, and a screw that has gone chalky or crazed will snap rather than loosen — often leaving the shank in the hole, which is a far worse problem than the screw it started as.

Frequently Asked Questions

What Tornado machines does the nylon screw 19124 fit?

It is used on the Tornado 98164 MWH-800 8-gallon self-contained extractor, the 98166 and 98167 20″ Marathon 800, the 98168 12 Gallon Self Contained extractor and the 98168 20″ Marathon 1200 in all series. Call 763-535-0770 with your model number if you are not sure.

Can I use a steel screw of the same size instead?

Not safely in every position. A nylon screw is often there precisely because it does not conduct — near a terminal, a board or a switch a steel substitute can turn a harmless fixing into a live one. It also will not seize into a plastic boss the way a metal screw does.

My nylon screw keeps tearing its slot — what am I doing wrong?

Usually the driver. A slot is the weakest drive there is and a nylon slot is weaker still, so a blade that is too narrow tears it out on the first firm turn. Use a blade that fills the slot across its full width and depth and keep it square, and stop at finger-firm — #6-32 in nylon has a very low strip torque.
