Default Wheel hex source...?

Anyone know of a source for the 7mm hex for mounting wheels? Iíve lost one in my junk room and now have one crawler down. I canít seem to find any on fleaBay or the China sites.

A few options pop up from various vehicles when I type in 7mm hex into Google. Other than that maybe searching for one of the specific vehicle hexes. There's also the brass hex extensions on eBay and possibly RC4WD may sell gelande metal hexes separately

Do you mean 7mm wide?

Traxxas aluminum ones are great, cheap, and readily available.

The 7mm micro hexes. Trail Trekker, LMcC, HBX, RGT, whatever brand of aftermarket. Iíll have another look later when I get a chance.

Don't forget, the trekker is 7 mm but has a slightly thicker hex than the others to give it the extra width

Maybe some 3D printed hexes? Would be a super quick/easy design....

You can find anything on Amazon I'm finding. Their RC stuff changes almost hourly with the way Fulfillment by Amazon works. I got some 8mm hexes earlier this week from Amazon. Here is a replacement part for a WL vehicle, looks almost exactly the same as the 8mm's I just ordered.

Those are 7mm thick and a 12mm hex. Looked at them, too.

Iíve got a mini lathe. If I could only find some hex stock in nylon, delrin, or some hard plastic.

Measuring the couple of hexes I have on hand they are exactly 7mm across flat to flat. Duh? The ID is nearly 4mm where the axle passes through. So after scratching my head I happened across some plastic computer standoffs. 7mm hex and an m4 thread. An m4 hole to be tapped out needs to start as 3.4544mm.

So my thinking is I can cut them to length and then make a notch for the axle pin.

I was going to suggest the same thing, hex bar stock would even work, but the stand offs make it easier to drill the center open

I havenít calipered the axle shaft yet. But I think the standoffs may slip on very snugly.

Uh.. Are you sure the product I linked is a 12mm hub? In the Q&A there are two responses specifying outside diameter is 7mm rather than 12mm, and I definitely ordered an 8mm set from the same source w/o any issues.

I was wrong. I assUmed that since these were mostly monster truck looking RCs that they used a 12mm. This link shows them as 6mm but usually their measurements are wrong anyway.

The standoffs came in the mail today. I dug out my year old micro lathe thatís never been used and fired it up. The standoffs I ordered were medium length of the ones offered and I was hoping to get 3-4 off of one, but these donít pass all the way through.




I can only get two per standoff due to the center being solid.


Trekker on the lower right. Any recommendations for cutting a pin groove? Iím thing of just chucking a little bur bit from my Dremel into the lathe and work it that way. Better to have one end stationary than both sides moving.
