The Honda 90034-402-000 Stud Bolt (6X50) is a genuine OEM fastener designed for Honda WB20 and WD20 water pumps. As a direct Honda OEM part, it is manufactured to the exact dimensions and thread specification of the original, ensuring a proper fit without guesswork. Honda supersedes hardware at serial breaks, so confirm your pump's serial number against the fitment table before ordering.

Key Features

  • Genuine OEM Hardware — sourced directly from Honda, this stud bolt carries the exact thread pitch, length, and diameter of the original fastener it replaces
  • Exact Dimensional Match — the 6X50 specification identifies both thread size and shank length, so this part installs without alteration to the original hardware arrangement
  • Water Pump Fitment — listed for Honda WB20 and WD20 water pumps; check your serial number against the fitment table to confirm the correct application

A stud bolt is a fully threaded or partially threaded rod that anchors two components together using nuts on one or both ends — unlike a conventional bolt, it remains in place as a fixed post while assembly and disassembly happen around it. In water pump applications, stud bolts are commonly used to secure pump housings, covers, and flanged connections under the clamping loads and vibration a running pump generates. A damaged, corroded, or incorrect-length stud compromises clamping force and can lead to joint failure or leaks during operation.
