Learn how to diagnose and fix loose or missing wheel hex pins on your RC crawler with this step-by-step guide featuring Vanquish Products Wheel Hex Pins M2x10.
Quick answer
If your RC crawler's wheel hex pins are missing, bent, or too loose to hold the wheel securely, replace them with Vanquish Products Wheel Hex Pins M2x10. These pins are a direct fit for most standard 12mm hexes and restore proper wheel retention.
Why wheel hex pins fail
Wheel hex pins are small but critical parts. They lock the wheel hex onto the axle shaft. Over time, the pins can bend from hard impacts, fall out if the retaining grub screw loosens, or simply get lost during a trail repair. Running without a pin puts stress on the remaining pins and can cause the wheel to wobble or detach.
When to replace vs. reinstall
If you find a pin on the ground and it's straight, you can often reinstall it. But if the pin is bent, has a burr, or the original grub screw is stripped, replacement is the safer choice. Vanquish Products Wheel Hex Pins M2x10 come as a set, so you can replace all four at once for consistent performance.
Diagnosis and replacement steps
- Symptom: Wheel wobbles or falls off during driving. One or more hex pins are missing, bent, or no longer engage the axle slot. Inspect all four hex pins on the affected axle. If any are missing or damaged, proceed to the next step.
- Likely cause: The hex pin either bent from a hard landing or the grub screw backed out, allowing the pin to slide out. On some builds, the pin can also shear if the wheel binds against rocks. Check the grub screw on the axle stub. If it's loose, tighten it before inserting a new pin. If it's stripped, you may need a replacement axle stub.
- Corrective action: Remove the wheel and hex. Slide the new Vanquish Products Wheel Hex Pin M2x10 through the hex and into the axle slot. Ensure the pin seats fully and the grub screw is snug. Reinstall the wheel and test for wobble. Torque the grub screw to a light snug—over-tightening can strip the threads. Use threadlocker if the screw keeps backing out.
- Stop or choose another option: If the axle slot is wallowed out or the grub screw threads are stripped, a new pin will not fix the problem. In that case, replace the axle stub or upgrade to a hex system that uses a captured pin design. Stop here if the axle itself is damaged. A new pin won't solve a worn slot.
