Screw 10-32 x 3/4″ 7BR005

The Screw 10-32 x 3/4″ (part# 7BR005) 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 specified 10-32 machine screw of 3/4 inch length used at particular fastening points.

What the Screw 10-32 x 3/4″ does

Machines like this carry the same thread in several lengths, and the parts list keeps them apart for a reason. Three quarters of an inch gives full engagement where the stack-up is shallow, and putting a longer screw in the same hole means it bottoms out or protrudes into a space where something moves. The screw that feels tight while the joint stays loose is nearly always the wrong length.

When to replace the Screw 10-32 x 3/4″ (7BR005)

Replace it when the drive recess is chewed, when the thread is galled or stripped, or when corrosion has seized it. Any screw that had to be extracted goes in the bin rather than back in the machine.

Screw 7BR005 — fitment and installation notes

Keep the lengths separated during a strip-down, ideally by putting each screw back in the hole it came from as soon as the part is off. Start every 10-32 by hand because the fine thread cross-threads easily, and tighten to a firm seat rather than to the limit of the driver. 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.
