Flojet 20131-002 Screw Kit, 2 Pieces
The Flojet 20131-002 is a genuine screw kit containing two screws, supplied under the factory reference for that particular fastener. Flojet lists several two-screw kits with different specifications, which is why the part number matters more than the description.
Two similar screws from different kits can differ in ways that are invisible side by side and consequential once fitted. Thread pitch determines whether it engages the boss properly. Length determines whether it clamps or bottoms out. Head form determines how the load is spread and whether the screw sits flush. Material determines whether it will still come out in three years’ time. None of those are things you can judge by eye, and getting one wrong usually shows up later as a leak or a stripped housing.
Because these are inexpensive and easy to lose in a bilge or a locker, a spare set is worth keeping with the pump. Tighten to a firm hand feel rather than driving them hard — plastic bosses strip with little warning, and a stripped boss turns a simple service into a housing replacement. Confirm the part number against the parts breakdown for your pump before ordering.

Frequently Asked Questions
Q: How can two screw kits for the same pump be different?
Because different positions in the pump need different fasteners. Head, motor mount and bracket screws may all differ in length or thread even on one machine.
Q: What is the risk of a screw that is slightly too long?
It bottoms in the boss before the head clamps the component, so the joint feels tight while carrying almost no clamping load. That is a very common cause of a rebuild that leaks.
Q: And one slightly too short?
It engages too few threads, concentrating the load on the first turn or two of the boss, which is where a plastic thread strips first.
Q: Can I use stainless screws instead?
Only if they match in every dimension. Material alone is not the whole specification, and a stainless screw of the wrong length causes the same problems as any other.
