Screw #10-24 x 5/8 in 33451

The Screw #10-24 x 5/8 in (part# 33451) is a genuine Tacony OEM thread-forming machine screw used on the Tornado CK 3030 wide-area vacuum (Model 93030) in Series G, H and J, and on the brush motor assembly. It fits more than one machine, which is why it is listed here once rather than duplicated per model. Fits Tornado 93030, Tornado 93031, CleanMax CM-WAV and Powr-Flite PF2030.

Tacony specifies a thread-forming screw here rather than a plain machine screw. The tip carries cutting flutes that form a mating thread as the screw is driven into an untapped boss, which gives a tighter, more vibration-resistant joint than a machine screw running in a moulded thread. That matters at the brush motor, where the fastener is holding a spinning mass against continuous vibration for the life of the machine.

The practical consequence is that these screws should not be treated as infinitely reusable. Every time one is backed out and driven in again it cuts a slightly looser thread, and eventually the boss will not hold torque at all. If you have had the brush motor out — for a bearing, a belt or a pulley — fit fresh screws on reassembly. It is a few dollars against the risk of a motor mount working loose in service.

Series D, E and F use a different number: those machines take part# 01993, listed separately. Confirm your series before ordering.

Frequently Asked Questions

What does the Screw #10-24 x 5/8 in do on the Tornado 93030?

It is the thread-forming #10-24 screw that secures the brush motor and adjacent housing panels. Being thread-forming, it cuts its own thread into the moulded boss rather than relying on a pre-tapped hole.

Is this the same screw as part# 01993?

No. 01993 is the equivalent screw for Series D, E and F and is listed separately. Both are #10-24 x 5/8 in but Tacony carries them under different numbers for different series — check the series letter on your machine’s data label and order the matching number.

How do I know if my Screw #10-24 x 5/8 in needs replacing?

Replace it if the drive recess has cammed out, the thread-forming flutes at the tip are rounded or damaged, the shank is bent, or the screw no longer pulls the motor or panel down tight. Thread-forming screws lose their bite after repeated removal and refitting, so fit a new one whenever a brush motor has been out rather than reusing a screw that has already cut its thread several times.
