The Honda 31148-PD1-004 Screw-Washer (4X25) is a genuine OEM fastener designed for BF115, BF130, BF135, BF140, and BF150 outboard motors and the H6522 compact tractor. As a direct Honda OEM part, it matches the original specification exactly, ensuring a proper fit without guesswork. This part is listed across multiple machines, so confirm your serial number against the fitment table before ordering to make sure you have the right variant for your unit.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this screw-washer meets the same specification as the fastener installed at the factory, so it seats and torques correctly every time.
- Integrated Washer Design — the captive washer distributes clamping load evenly across the mating surface, eliminating the need for a separate loose washer during reassembly.
- Broad Fitment — covers BF115, BF130, BF135, BF140, and BF150 outboard motors as well as the H6522 compact tractor; verify your serial number against the fitment table to confirm the correct application.
- Check Your Serial Number — Honda supersedes hardware at production breaks, so match your machine's serial number to the fitment table before ordering.
A screw-washer combines a threaded fastener and a washer into a single captive assembly. The integrated washer spreads the clamping force over a wider surface area than a bare screw head alone, helping to secure panels, covers, and components without concentrating stress on the mating material. When a screw-washer loosens or is lost, the component it secures can shift or vibrate free during operation, making prompt replacement with the correct part essential for keeping the machine assembled as intended.
