My skate chassis was missing a screw. Two of them to be exact.
I’m not talking about the ones that act as axles for the wheels, I mean the ones that hold the chassis together. I looked all over for a replacement, but didn’t come up with anything. I measured the screw and found it was 10mm long, flat head style, with a hex drive of 2.5mm. The diameter I had to guess on, but luckily I got it right. The size was M4. I ordered a dozen of them online for a couple bucks plus shipping.
I swear, bolts fall off inline skates all the time and they are usually a pain to replace. So now if it ever happens to you, you’ll know what to get. Oh, just FYI this was on a Bauer Tuuk chassis, but I checked a Mission HiLo chassis I had and the bolt was the same. The head had a diameter just a tiny bit bigger than OEM but it didn’t seem to make any difference.
