The Honda Q14-0000-077 Hexagon Bolt (8x1.25x15) is a genuine OEM fastener designed for WDP20 and WDP30 diaphragm water pumps. As a factory-sourced component, this bolt is manufactured to the exact dimensions Honda specifies, ensuring proper torque retention and a secure fit when servicing these pumps. When you need to restore a WDP20 or WDP30 to working order, using the correct OEM hardware is the straightforward way to do it right the first time.
Key Features
- Genuine OEM Honda Hardware — sourced directly from Honda, this bolt meets the exact thread pitch, length, and head dimensions specified for the WDP20 and WDP30 diaphragm water pumps.
- Exact Dimensions — the M8 x 1.25 x 15 mm specification means this bolt seats and torques correctly without the guesswork that comes with sourcing generic hardware.
- Diaphragm Pump Fitment — listed for Honda WDP20 and WDP30 diaphragm water pumps; verify your unit's serial number against the fitment table to confirm this is the correct bolt for your application.
A hexagon bolt of this type is a standard fastener used to secure components during assembly and service of the WDP20 and WDP30 diaphragm water pumps. Diaphragm pumps rely on precise clamping force throughout their assemblies to maintain sealed, leak-free operation — a bolt that is the wrong length, thread pitch, or grade can compromise that clamping and lead to leaks or loosening under the vibration these pumps generate during use. Using the correct OEM replacement bolt, part number Q14-0000-077, ensures the joint is restored to Honda's original specification.
