Screw #8 x 1-1/4 in A090-0300

The Screw #8 x 1-1/4 in (part# A090-0300) is the long factory fastener on the Tornado CK-LW 13/1 ProLite, models 97130 (115V) and 97131 (230V), and on the Powr-Flite PF62EC.

Length is the whole point of this one. At an inch and a quarter it passes through more than one moulding before it picks up thread, which is how the machine holds stacked components together in a single fixing. Substitute a shorter #8 and everything appears to assemble correctly — the head pulls down, the panel sits flush — while the screw is only gripping the first layer. The joint then works loose under vibration and the operator reports a rattle nobody can find.

Getting fasteners right

The factory breakdown lists four fastener numbers for this machine, and they are not interchangeable: this #8 x 1-1/4 in, the #10 x 1/2 in (A090-0200), the 10-24 x 1 in machine screw (A090-0400) and the nyloc nut that goes with it (A090-0500). Sorting them into a labelled tray at the start of a strip-down saves more time than it costs, and it is the difference between a machine that goes back together right and one that comes back.

Thread into plastic to firm only. If a boss spins, stop — a stripped boss is a moulding problem, not a fastener problem.

Frequently Asked Questions

Which machines does this screw fit?

The Tornado CK-LW 13/1 ProLite, models 97130 and 97131, and the Powr-Flite PF62EC.

Can I use a shorter #8 screw instead?

No. The length is what lets it pass through more than one moulding before it picks up thread. A shorter screw looks right when assembled and grips only the first layer, then works loose under vibration.

How many fastener types does this machine use?

Four on this breakdown: A090-0200, A090-0300, A090-0400 and the nyloc nut A090-0500. They are not interchangeable.
