Key Features
- Genuine OEM Fastener — sourced directly from Honda, this self-locking nut matches the thread pitch, locking torque, and dimensional tolerances specified for these machines
- Self-Locking Design — the prevailing-torque locking feature resists loosening from vibration, maintaining a secure joint under the operating conditions these machines produce
- Broad Honda Fitment — listed for H3011 and H3013 riding mowers, HS520 and HS720 single-stage snow blowers, HSS724, HSS928, and HSS1332 two-stage snow blowers, and HT3810, HT3813, and HT4213 lawn tractors
- Verify Your Serial Number — Honda revises parts at production breaks, so confirm part number 90118-961-000 against your machine's serial number and parts diagram before ordering
A self-lock nut uses an internal locking element — typically a deformed thread section or nylon insert — that creates resistance when the nut is driven onto a bolt, keeping the fastener from backing off under vibration or cyclical load. On riding mowers, lawn tractors, and snow blowers, drivetrain and auger operation generate sustained vibration that can gradually work a standard nut loose; the prevailing-torque design of this nut maintains clamping force through that vibration. When this nut is worn, cross-threaded, or missing from a fastened joint, the connection it secures can shift or come out of adjustment, affecting the performance and serviceability of the machine.
