i gave a try since it's only $15. they are too long for our car.

how people install these?

 

Nice option. I chose to use alan head screws with lock tight on the thread and filled the head with silicone. They can be removed with a set of vise grips and some elbow grease but it definitely makes it a lot harder for the thief. The screws I used are a lot stronger than the ones in this thread.

 

i tried them and they broke while installing. Lucky it was through amazon so I returned them. They are a plastic screw and not really metal (the ones i got).

 

I got the ones from McGard(77796) and they fit just fine. You can always throw a couple of washers on there.

 

You definitely don't want to "secure" your seats with plastic bolts. See posts #18 & 19. Kodokan's seat locks are specifically designed for this task.

Whether or not a thief can bypass a deterrent doesn't mean that it isn't worth using the deterrent. In any case, worth is always highly subjective and it's up to each individual to determine what measures he/she is willing to take to reduce theft. Don't assume that your preferences are universal regardless of the topic.

A garage certainly isn't any guarantee of theft prevention either (neither is the popular suggestion of a hard top, etc). Spend some time searching/reading right here. There are certainly people who have had seats and more stolen from their garage.

10 seconds is an extreme exaggeration as well. Please post a video if you can actually remove 4 of these with Vise Grips in 10 seconds.

 

There are a few sets of mcgard on eBay now for $7

Just installed and works perfectly

 

I'm not sure what happened to my reply... but I'll post again...

So yea... don't torque these things too hard. I hand torqued mine and snapped the head right off.

 

^ makes you wonder how safe those bolts are at keeping the seat in place during an accident.

 

Another instance where it’s clear that these were never designed to withstand even minimal amounts of force. Makes sense since these were meant to hold center caps onto wheels that are most likely aluminum (won’t be subject to much torque or shear stress). In a car wreck, inertia is going to be a bitch to these!

 

Fk it, I'll torque down one on the front and rear of each seat. I can't wait indefinitely for Kodokan to respond.
I decided on the gorilla ones...they seem slightly more robust and only $9 on amazon.
