Description
Overview:
This Self Lock Nut is a Genuine Honda part designed for secure fastening on small Honda petrol engines, including GX35 and GX35N. It is an M5 (5 mm) hexagonal self-locking nut made from durable steel with a corrosion-resistant finish, using a nylon insert to maintain clamping force under vibration. The nut is intended for engine assemblies and attachments commonly found on garden and construction machinery such as brushcutters, hedge trimmers, blowers, and compact power units. By resisting loosening in high-vibration conditions, it helps protect key components and keeps your machine operating reliably. Suitable wherever an M5 self-locking fastener is specified on compatible Honda engines and equipment.
Key Features:
- Genuine Honda OEM component for correct fit and reliable performance
- M5 size for precise fastening on Honda engine assemblies and accessories
- Nylon insert provides prevailing torque to resist loosening under vibration
- Steel construction with protective finish for durability and corrosion resistance
- Helps maintain clamp load to protect engine covers, guards, and linkages
- Simple to fit with standard metric hand tools; no special tools required
- Suitable for repeated service use within normal limits of a nylon-insert nut
- Widely used across Honda mini 4-stroke ranges for consistent compatibility
Typical Applications:
Used on Honda small engines and handheld machines to secure shrouds, recoil starters, guards and brackets, handle assemblies, throttle and cable clips, and air filter housings. Ideal wherever an M5 self-locking fastener is needed to withstand engine vibration and daily use in landscaping, grounds maintenance, and light construction tasks.
