Flojet 20131-000 Screw Kit, 2 Pieces
The Flojet 20131-000 is a genuine screw kit containing two screws, supplied under the factory part reference for that fastener. It provides the correct fasteners for a specific position in the pump rather than a generic substitute from a drawer.
Fasteners in a pump are more particular than they look. Thread form, length, head type and the material they are made from are all chosen for the job: a screw that is slightly too long bottoms out before it clamps, one that is too short strips a plastic boss, and one made of the wrong material corrodes solid in a wet assembly and destroys the thread when it is eventually removed. None of that is visible when you are holding two similar-looking screws side by side.
The corrosion point is worth dwelling on in marine use. A mild steel screw in a damp polymer housing will seize within a season, and the force needed to break it free usually takes the boss with it — turning a five-minute service job into a housing replacement. Using the manufacturer’s own fasteners avoids that, and keeping a spare set aboard means a dropped screw never stops a repair.

Frequently Asked Questions
Q: Does it really matter if I use a similar screw from the workshop?
Often, yes. Length and thread form decide whether the joint clamps properly, and material decides whether you can ever get the screw out again.
Q: Why do screws seize in plastic housings?
Because corrosion products from the fastener expand into the thread. In a polymer boss there is nothing hard to resist that, so the thread is damaged as the screw is forced out.
Q: How tight should pump screws be?
Firm and even, working around the pattern rather than fully tightening one at a time. Plastic bosses give very little warning before they strip.
Q: Should I use thread lock?
Only if the instructions call for it. Many thread-locking compounds attack polymers, and in a damp assembly they can make later removal considerably harder.
