    A chance of irony...

    This past spring I built up my bike and put on a Raceface Sixc crank. It has that stupid 16mm hex nut on it to extract the cranks with and it's not included with the cranks. Go figure.

    Believe it or not, a 16mm nut isn't all that easy to find.

    So while making a purchase at Amazon, I found the 16mm tool for $5-6. I bought it along with something else I needed.

    I opened the box and didn't recognize what was in it. It was a tap set (very long Btw) and heli-coils by Unior. Wtf? It's for cranks. There's a L and R taps with reamer on them (hence their length) and two different colored heli-coils. I looked them up online and found that they were only $8 or something close to what I paid for the 16mm nut. I figured that the shop I'm part time at might need them so I tossed them in my toolbox.

    2 weeks later Eric and myself were riding and he stops in the middle of a climb. His pedal was loose. I gave him my wrench and he tightened it up. Literally 2 strokes and he stopped again. The crank was stripped. We ended the ride and went to grab a bite.

    Me- call the shop.
    E- Sram's website says its a 3 year warranty. I bought it used as a demo 2 years ago, but the bike is 3 years old. Think they'll cover it?
    Me- Maybe. Give it a try.
    E- The shop said to bring it in and they'll try to warranty it.
    ....
    ...
    ...
    (In my head) DING!
    Me- Bring it to work tomorrow! I can fix it!

    I had to ground down the heli-coil so it wasn't sticking out the back of the crank 5mm. We bored and tapped it in 5 minutes, cleaned out the hole and applied red loctite. The loctite dried for 2 days and he torqued the pedal back in.

    Boom! It's been perfect ever since!

    What were the odds of getting the wrong thing, holding on to it and needing it 2 weeks later?

    Here was my solution for a 16mm hex...

    Necessity is the mother of invention...

    I have had the non-drive side crank loosen from the spindle only once, but it torqued back up (50 Nm) and has not experienced any more issue.

    I didn't have a 16 mm hex, and found that a 16 mm is not too common (not common enough when you're ready to go ride and you need a quick fix). I called around and couldn't find one locally available.



    I went to the big box hardware and looked for a 16 mm headed bolt and a few nuts to fit it. This would be my ghetto 16 mm hex that could be used with a torque wrench.

    I found a grade 8, 7/16-14 x 1-1/4" bolt. The head of the bolt was 16 mm. Two nuts to fit the bolt, tighten them onto the bolt and I used a deep socket to do the deed.

    Where did you get the bolt/nuts from? Lowes and Home depot didn't have them when I looked. At that point I figured I was wasting more money and time driving around rather than just ordering one. Fahn

    I can't remember if it was Lowe's or Home Depot, but I think it was Lowe's.

    Here's the packages...grade 8, 7/16-14 x 1-1/4" bolt.

    the bolt head is 5/8" (16mm {actually 15.875})

    I was thinking that it was 5/8" since the threads weren't metric.

    This is why techs are all pack rats.

    The only unusual thing is you needed it only two weeks later and not two years and then forgot where you put it.

    You know what's even stranger about this?
    -In the 20 years I've been a part-time wrench monkey, I've never seen these used before.
    -The bike I used these on was a $2500-3000 bike with Sram cranks. Go figure. They should go in the garbage can with all those Avid brakes.
    -My intent was to keep these for the shop I work at since we get in a lot of low end bikes and dept. store bikes. We also service a ton of summer camp bikes that kids destroy. It made sense to keep this kit for them.

    While I prefer to not have to use a Heli-coil, they are wonderful tools when your choices are limited. They're generally quick and easy to prepare and install. Glad to hear how this worked out for you.

    Cheers!

    I haven't turned wrenches for a living in over 17 years, still have my boxes of accumulated crap in the garage. You never when you'll need it.

    As a rule of thumb for all of that stuff my wife says needs to go.

    You'll need it within days of throwing it out.

    I did a winter cleaning about a month ago- sure as shit a week or so later some of the stuff I cleared out would have been useful to have.

    Race Face make an 8mm to 16mm adapter - they should, but don't, include one with their cranksets.
