This is a pack of four replacement Tekno RC M5 Serrated Flanged Locknuts. These are used with TKR5570B M5 threaded stub axles for the SCT410, but can also be used anywhere an M5 serrated locknut is required. These nuts will ensure your wheels stay on your vehicle. M4 serrated locknuts simply can’t compare and can strip or come loose much easier than an M5 nut.


  •     Massive M5 thread and serrated back ensures your wheels will stay on
  •     Less wasted wheels due to stripped out wheel hexes
  •     Larger thread is more durable and will last longer than any aluminum M4 nut
  •     Aluminum construction is light weight
  •     Black anodized for wear

Note: Requires an 8mm nut driver or socket for installation.  Most glow plug wrenches will work here.

very nice lightweight nuts. they have very sharp serrations that make them bite in HARD and are difficult to even remove if tightened down a lot.

I lost one of these on the track when i forgot to tighten them. impossible to find in the dirt.

minus 1 star for the high price ... There is a cheaper alternative by losi but they are heavier (steel) and lack the nice serrations.

Not sure i agree with tekno using this weird M5 size. at least now i have 3 spares so I shouldn't have to buy these ever again.
