The Honda Q14-0000-002 Stud (10X1.5X40) is a genuine OEM fastener designed for WDP20 and WDP30 diaphragm water pumps. As a direct Honda OEM component, this stud is manufactured to the same specifications as the original, ensuring a correct, secure fit without improvisation or adaptation. Honda supersedes parts at serial breaks, so confirm your pump's serial number against the fitment table before ordering to make sure part number Q14-0000-002 is the right stud for your unit.
Key Features
- Genuine OEM Fastener — sourced directly from Honda, this stud matches the thread pitch, diameter, and length of the original hardware used on WDP20 and WDP30 diaphragm water pumps at the time of manufacture.
- Correct Thread Specification — the 10×1.5×40 designation identifies the exact metric thread size and stud length, so it engages mating threads properly and clamps assembled components as intended.
- Diaphragm Pump Fitment — listed for Honda WDP20 and WDP30 diaphragm water pumps; verify your serial number against the fitment table, as Honda may have revised hardware at a serial break.
A stud is a headless threaded fastener — threaded at both ends — used to secure pump components together by accepting a nut on the exposed end once installed. On a diaphragm water pump like the WDP20 and WDP30, studs hold critical assemblies in alignment and under consistent clamping load as the reciprocating diaphragm cycles continuously during operation. A stud that is stripped, corroded, or damaged can lead to loose assemblies, improper sealing, and pump inefficiency, making timely replacement with the correct OEM hardware essential to keeping the pump working as intended.
