Description

Overview:
This Non-Genuine M12 self-locking nut is a durable steel fastener for JCB construction machinery, including site dumpers such as the 6T-1 and popular backhoe loaders like the 3CX. It is designed to maintain clamping force in high-vibration conditions, helping prevent joints from loosening during heavy use. The M12 metric thread suits a wide range of assemblies on chassis, bodywork, drivetrain brackets, and ancillary mounts commonly found across JCB equipment. Supplied as an aftermarket replacement, it cross-references the OE part number 1370/0403Z for easy identification. Use it where a secure, tamper-resistant fastening is needed without frequent re-torqueing. The robust construction and self-locking mechanism make it well suited to demanding site work and routine maintenance tasks.

Key Features:
- Non-Genuine replacement matching the form and function of the OE reference 1370/0403Z
- M12 standard metric size for broad compatibility across JCB machines
- Self-locking design helps resist loosening from shock and vibration
- Strong steel construction for reliable clamping in heavy-duty use
- Suitable for frequent on-site maintenance and repair tasks
- Helps reduce re-tightening intervals in high-vibration assemblies
- Clean hex form for good spanner/socket engagement and straightforward fitting
- Compatible with common M12 bolts/studs used on frames, brackets, and guards

Typical Applications:
Used on JCB site dumpers, backhoe loaders, compact excavators, and FASTRAC models where a secure, vibration-resistant M12 fastening is required. Typical locations include engine and transmission brackets, suspension and axle fixtures, body panels, guard mounts, hydraulic hose clamps, and general chassis hardware on machines working in construction, agriculture, landscaping, and plant hire.

Also known as:
Lock nut, self-lock nut, M12 locking nut, prevailing torque nut, M12 hex locknut, M12 self-locking fastener, replacement JCB locknut, aftermarket M12 nut.
