M5 Bolt for Racks - Theft Proof

I have a gorgeous Nitto rack. I don't want someone to be able to take it by removing 4 bolts with a hex.

Any alternatives? Thanks.

Put it on and file the heads down or go get some anti-theft/anti-tamper nuts somewhere. A fastener or hardware store might carry the specialty nut like that.

You can super-glue a ball bearing in the hex head. Use acetone to dissolve the glue if you need to make an adjustment. Or, use a torx head bolt.

Both could still be removed if a thief had the right substance or tool.

Torx would be my first suggestion, or hex pin. Any good tamper resistant bolt or screw is of course going to require that you have the appropriate driver to install and remove them.
For alternatives check out something like this:

Are the tamper resistant bolts as strong as stainless steel allen bolts?
I have never heard of anyone stealing racks. Anyone who really covets his neighbours Nitto rack is probably honest enough to buy his own.

I have always thought of getting some sort of hard wax, like what fancy bottle tops are dipped in. Then filling bolt heads with that(not the threads). Then it more of a bother to take it off but if you just have the time, heat would be needed will melt it out and then you can remove it, That wax is harder and doesn't melt as easily as candles. I think its the same style of wax you might find at a stationary shop to seal fancy letters with.

Just something I have thought might be a deterrent. I don't know if this would actually work.

Stealing racks is common? Weld it on if your concern is rational or run your lock through them.

Exactly. I have nice King titanium water bottle cages and I'm not worried about someone stealing them.

I would simply get a leash, similar to one you lock your seat with, and use that. Short cable attached to your Ulock. Maybe use the same cable for both the rack and the seat - -

Once the nut and bolt are tight, you can mangle the threads of the bolt that stick out past the nut.
then you have to saw off the end to unscrew the nut.

in practical terms, just ride a beater that is not so nice looking , but works.

bike friendly, so popular to ride, and bike stealing ..
are frequent 2 sides of the same coin.

Are the tamper resistant bolts as strong as stainless steel allen bolts?
If they are made from the same grade of stainless steel, yes.


Any alternatives?
Restate.. ride a cheap looking bike that works well but is ugly , Overspray shiny stuff
and bring big, strong locks.. park next to the nicer bike with the inferior locks.

save the nice bike for the weekend clubby rides.

Security torx and thread lock. If it's that much of a problem get a cheap aluminum rack.

Loctite probably wouldn't be enough. You can still unscrew a bolt that has been Loctite'd in place; it just takes more effort.

I kind of like the poor man's alternative of intentionally stripping out the bolt. Be sure you Loctite the threads before you do it--not as a theft deterrent, but simply because you won't be able to tighten down the bolt if it loosens up. (I'd probably use the blue rather than the red.) If you ever need to remove the rack, you can drill out the bolts. I wouldn't try to saw a bolt off from the side, because you'd almost certainly damage your frame in the process.

If it loosens up, you didn't bugger the threads close enough to the nut or whatever it is screwed into - in any case, you would still be able to TIGHTEN it. Loosening it would be the problem.

Hard wax, what a joke.

Just place small forms (of the same dimensions) around the hexed bolts, and evenly pour cement over them. To remove them yourself, you'll need a large hammer, that makes a lot of noise!

You can even paint the cement to match the color of your bike!

- Slim

PS.

Glue can be quietly chipped at...A 4 cubic inch cement block, needs banging!

Worried about a rack? Unless you are into cycling most people wouldn't have any idea as to what it actually is. And, if a thief wants something than they are going to take the WHOLE bike. They certainly aren't going to take the time to unbolt a rack......

Rack trouble

I hate the idea of welding the rack to the frame so thats not an option in my book. If you could get a longer bolt and if your frame allows you to screw the bolt completely through the eyelet then you could screw a nut on to the "excess" of the bolt on the other side. Then that nut could be tac welded onto the bolt. This would work and if you wanted to remove it you could cut it off and not damage the frame. This is what I have been thinking of doing since I want to mount a trunk on the back rack and have it be secure. The trunk would be locked and bolted onto the rack from inside the trunk box. The only way it could be removed is if they take the entire rack.......hence the bolt idea. Here is the trunk that I am thinking of buying.
