HPI Racing Flange Lock Nut M4 RC Fastener - HPIZ684

The HPI Racing Z684 Flange Lock Nut M4 is a genuine HPI spare part supplying four M4 flange lock nuts for maintaining or repairing HPI Racing RC cars. Flange lock nuts are a staple fastener in RC car builds and repairs — the integrated flange distributes load across a wider surface area than a standard nut, while the nylon locking insert resists loosening caused by vibration during running. If you're restoring a stripped thread assembly or replacing lost hardware after a bash, keeping a pack of these on hand saves downtime at the track or bench.

Key Features

• M4 thread size suits a wide range of HPI Racing drivetrain, suspension, and chassis fastener positions
• Integrated flange spreads clamping load, reducing the risk of pull-through on plastic and composite components
• Nylon locking insert prevents nuts from working loose under the vibration typical of RC car running
• Pack of four provides enough hardware to address multiple fastener points in a single repair session
• Genuine HPI Racing part under style code HPIZ684, ensuring correct thread pitch and dimensional fit
