Screw #10-16 x 1/2″ 19565

The Screw #10-16 x 1/2″ (part# 19565) is a genuine Tacony OEM replacement part from the recovery and solution tank assembly of the Tornado Marathon SE 900 self-contained carpet extractor. It is the #10-16 self-tapping screw used to secure components to the tank.

What the Screw #10-16 x 1/2″ does

This is a #10-16 self-tapping screw, half an inch long, that cuts its own thread into a plastic boss on the tank assembly. Self-tappers like this are what hold most of the light components in place, and the thread they cut on first installation is the thread every future service depends on.

When to replace the Screw #10-16 x 1/2″ (19565)

Replace it when the point is dulled, the drive is rounded, or it is corroded. More importantly, replace it rather than reuse it if it has been removed several times — a self-tapper progressively wears the boss, and a fresh screw grips a tired boss better than an old one.

Screw 19565 — fitment and installation notes

Drive it back down the existing thread rather than cutting a new one: seat the screw, turn it backwards until you feel it drop into the original thread, then tighten. Cutting a second thread is what strips the boss. Tacony builds the Tornado Marathon SE 900 and the Powr-Flite Prowler PFX900S on a single machine platform, so this component carries across both brands rather than belonging to either one. It is a shared Tacony component and may fit additional models beyond those listed — call us and we will confirm against your serial number.
