The Honda 90121-V45-A00 Carriage Bolt (6X18) is a genuine OEM hardware fastener listed for Honda two-stage snow blowers and battery-powered zero-turn mowers. As a direct Honda OEM part, it is manufactured to the exact dimensions Honda specifies, making it a straightforward like-for-like swap when an original bolt needs replacement. This part is listed for the HS1332, HS724, HS928, HSS1332, HSS724, HSS928, HZ54, and HZ60 — verify your machine's model and serial number against the fitment table before ordering, as Honda supersedes hardware at serial breaks.
Key Features
- Genuine OEM Fastener — sourced directly from Honda, this carriage bolt matches the original thread pitch, shank diameter, and head profile specified for your machine
- Exact 6X18 Dimensions — the 6 mm diameter and 18 mm length are Honda-specified values; using a bolt of the wrong length or thread class can compromise the joint it secures
- Broad Model Coverage — listed for HS1332, HS724, HS928, HSS1332, HSS724, HSS928, HZ54, and HZ60; confirm your model and serial number against the fitment table to ensure this is the correct bolt for your unit
- Serial-Range Awareness — Honda updates hardware part numbers at production breaks, so always cross-reference your machine's serial number with the compatibility table before purchasing
A carriage bolt is a round-headed, square-necked fastener designed to resist turning as the nut is tightened, securing two components without requiring a tool on the bolt head. On Honda snow blowers and zero-turn mowers, these bolts hold structural and panel assemblies in place; a bolt that is stripped, corroded, or missing the correct dimensions can allow that connection to loosen under the vibration and load these machines generate. Replacing a worn or damaged bolt with the correct Honda OEM part restores the clamping force the joint was designed around.
