New Bike hitch bolt not long enough.

Good idea!
I tried it and was able to squeeze it through. I think I will try and find a bigger one than the one I tried, but it works.

 

The hitch is thick so some bolts are not long enough to inset the pin. I was trying to put my hitch on and the pin was too short, but works on my 4 runner.

 

Look for a pin for a Class V receiver. Our Class IV receiver has a little thicker walls than normal.

 

Ran into nearly the same thing with a Kuat bike rack ‘anti-wobble’ hitch bolt. Bolted it in and tightened with an impact driver, and got it out on the other side *just* enough to get the hitch bolt lock on it, but the bolt loosened slightly after a short trip and popped the lock off. $30 lock gone. Absolutely worthless, if you ask me. Also, I’d secure any pricey bike or rack to the hitch receiver itself with a chain. Any hitch pin lock can be defeated in 2 seconds by loosening the hitch bolt with an impact driver. Hitch pin locks are a visual deterrent only, and barely at that.

I’m surprised nobody has come up with a bulletproof solution for these loosening issues. They’re neverending, regardless if it’s a hitch bolt or if it’s the internal wedge-style tightener. They ALL come loose. I’ll try Loctite next on my bolt but, even as good of a product it is, I’m not very confident that even Loctite is up to the task. I suppose a regular bolt with lockwasher and nylon locknut might work. The only foolproof anti-loosening method is safety wiring or a castellated nut on a bolt drilled to accept a clevis/cotter pin, like a rear motorcycle axle.

 

I have a new Tacoma and my Yakima anti wobble pin isn’t long enough either. no previous issue with my 4Runner hitch. This new box is wider, and I’m not getting enough thread to feel comfortable.
I could buy a bolt, but then how do I put the lock on it.
If anyone has experienced this, where can I get a longer locking hitch pin?

 

I had that same bike rack. I used a small bolt and nut instead of the pin. I think it was 1/8" or something like that. Ya could use a bit of baling wire in a pinch.

 

I bought 1 of these in 2012 for my second gen. I still use it. Check that the thread pitch works with Yakima.

I also have one of these for a weight distribution hitch. They make a Yakima-compatible locking pin. Check the measurements on the drawing or call and confirm Tacoma compatibility. Customer service is super nice. I ordered a pin that didn't fit, they had made a product update and sent me the correct part.

The softride is a little smaller in profile so it tucks in well, has the nut insert so it works on any hollow tube for anti-rattle (standard 2-inch ball) but doesn't have a secondary safety pin so double-check it's actually locked on.

Paclock is nice but a little bulky, does not have the nut insert so it will only work with something pre threaded. It does have a secondary safety pin. Paclock is cool because you can order any of their locks keyed alike and any time. I have a hitch pin, 2 trailer coupler locks, and a padlock all keyed the same for an RV.

 

It is nice to have it tensioned up so it doesnt bounce and rattle as much. You wont get that from just throwing a normal pin in there.

Id just get a bolt with the same thread pitch that is a bit longer and machine it down on the end.

If you ask nice someone that is handy they might make one for you.
