The Honda 93406-08016-08 Bolt-Washer (8x16) is a genuine OEM fastener designed for Honda riding mowers, lawn tractors, and compact tractors. This combined bolt-and-washer unit is sourced directly from Honda, ensuring the correct thread specification, head dimensions, and integrated washer bearing surface for the application. This part is listed for the CD3009, CD3811, CD3813, H6522, HT3810, and HT3813 — verify your model and serial number against the fitment table before ordering, as Honda supersedes hardware at production breaks.
Key Features
- Genuine OEM Hardware — sourced directly from Honda, this bolt-washer carries the exact thread form and head geometry specified for these machines, so it seats and clamps as intended.
- Integrated Washer Design — the captive washer distributes clamping load evenly, eliminating the need to source a separate flat washer and reducing the risk of an incorrect fit.
- Broad Model Coverage — listed for Honda CD3009 and CD3811 riding mowers, CD3813, HT3810, and HT3813 lawn tractors, and the H6522 compact tractor; check your serial number against the fitment table to confirm the correct part for your unit.
A bolt-washer is a fastener that combines a machine bolt with a permanently attached or formed washer flange at its base. The integrated washer spreads the clamping force over a wider surface area than a plain bolt head alone, helping to keep components securely drawn together even under vibration — a condition common in mowing and tractor operation. When this type of fastener is lost, damaged, or stripped, replacing it with the correct OEM part number 93406-08016-08 ensures the joint is restored to its original specification.
