Honda 90108-VF9-A00 Socket Bolt (6X15)

The Honda 90108-VF9-A00 Socket Bolt (6X15) is a genuine OEM fastener designed for UMK422 and UMK431 trimmers. As a direct Honda OEM component, this socket bolt is produced to the same specifications as the original hardware installed at the factory. This part fits UMK422 and UMK431 trimmers — verify your unit's serial number against the fitment table to confirm the correct application before ordering.

Key Features

• Genuine Honda OEM Hardware — sourced directly from Honda, ensuring the correct thread pitch, head size, and dimensional spec for the UMK422 and UMK431 trimmer platform
• Direct Replacement — an exact match for the original socket bolt, allowing straightforward installation without reworking or adapting the mounting point
• Serial Number Verification Recommended — Honda updates fastener specifications at production serial breaks, so cross-check your trimmer's serial number against the fitment table to confirm this is the right bolt for your unit

A socket bolt is a threaded fastener driven by an internal hex (Allen) key rather than an external wrench head, allowing it to seat flush or recessed in tight spaces where a standard bolt head would not clear surrounding components. In a trimmer like the UMK422 and UMK431, socket bolts secure assemblies where access is limited and a low-profile fastener head is required. A stripped, damaged, or missing bolt can allow components to work loose during operation, so replacing worn hardware with the correct OEM part keeps the trimmer properly assembled and functioning as intended.
