Screw 10-32 x 3/8″ 7BH004

The Screw 10-32 x 3/8″ (part# 7BH004) is a genuine Tacony OEM replacement part from the brush assembly of the Tornado Marathon SE 900 self-contained carpet extractor. It is the specified 10-32 fine thread screw at 3/8 inch length, used in shallow brush assembly joints.

What the Screw 10-32 x 3/8″ does

Three eighths of an inch is a deliberately short fastener, used where there is very little depth behind the hole and a longer screw would break through or foul something on the other side. Because 10-32 screws on this machine exist in several lengths and all look alike once they are out, the short one is the one most often replaced with something longer during a hurried reassembly, and that is exactly the substitution the design cannot tolerate.

When to replace the Screw 10-32 x 3/8″ (7BH004)

Replace it when the drive recess is rounded, when the thread is galled or stripped, or when corrosion has it binding. Any screw that had to be forced out has dragged its thread and should not go back into a fine tapped hole.

Screw 7BH004 — fitment and installation notes

Keep the 10-32 lengths separated during a strip-down, ideally by returning each screw to its own hole as soon as the part is off. Start it by hand so the fine thread engages cleanly, and tighten to a firm seat without leaning on 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.
