The Honda Q14-0000-051 Hexagon Bolt (12X1.75X50) is a genuine OEM fastener designed for WDP20 and WDP30 diaphragm water pumps. As a factory-original component, this bolt is produced to the same specifications Honda used when the pump was built, ensuring a correct, rattle-free fit every time. Confirm compatibility by checking your pump's serial number against the fitment table before ordering.
Key Features
- Genuine OEM Fastener — sourced directly from Honda, so thread pitch, shank diameter, and length match the original bolt exactly, with no guesswork on sizing.
- Exact Specification — the M12 x 1.75 x 50 mm dimensions are specific to this application; using an incorrect fastener can result in improper clamping or stripped threads.
- Diaphragm Pump Fitment — built for WDP20 and WDP30 diaphragm water pumps; always cross-reference your pump's serial number with the fitment table to confirm the correct part.
A hex bolt of this specification serves as a structural fastener within the WDP20 and WDP30 diaphragm water pumps, securing pump components firmly together so the reciprocating diaphragm mechanism can generate consistent pressure and flow. When a fastener is the wrong size, under-torqued, or worn, it can allow joint faces to shift or separate, compromising the pump's ability to move fluid reliably. Replacing a damaged or missing bolt with the correct genuine part, part number Q14-0000-051, restores proper clamping and keeps the pump operating as intended.
