Bumper bolts
 
so i have a 98 TJ Sport and i have 4 Hex bolts on the top of my bumper where it attaches to the frame. and someone i know also has a 98TJ Sport but he has 4 Torx bolts. why is that? idk if the torx are aftermarket or if the hex are aftermarket. any reason why?

factory was torx.

Geoff@Bestop 10-27-2010 11:42 PM

Torx are factory, and someone got annoyed enough with yours to replace them. Bumper bolts should be high grade bolts - check the marks on the head of the bolt.

Sometimes when people lose bolts they replace with anything handy (we always mean to replace with correct stuff, but ...). You don't need the torx, but get grade 8-ish bolts.

that answers my question. another question is though, will having the hex on there cause any problems.

the reason im asking is because i had to take the bumper off to put on my jack mount and it was a b***h getting the rear bolts back in on both sides. i didnt strip them, it just seemed a lot harder than it should have been.

i mean are the torx better to have than the hex, or does it make a difference?

Torx are a better bolt since they dont strip as easy as a hex bolt will...

makes sense..
should i buy factory torx bolts or should i upgrade to a stronger torx? if so, what would that be?

Just go with Grade 8 bolts and use anti-seize on the threads. Torx head bolts end up stripping out or breaking the torx bit when they get seized.

In my experience, the opposite is true.
Maybe it's my technique.:D

how do i tell what grade the hex i have are?
2 of them have 2 lines on the top of them and 2 have 3 lines.
what grade are those?

It won't cost you all that much to replace them with 8.8 if you are concerned (regardless of the head). Just because they are hex doesn't make them bad. In fact, I have had more problems with Torx.

OregonTJ 10-28-2010 07:56 PM

3 lines is a grade 5 bolt, 5 is a grade 8. no line are cheap junk.....google bolt grades for info.

You should be using a grade 5 or 8.

When putting more than 1 bolt in the same piece (bumper in this case) put all 4 bolts in finger tight or so as verses completly tightening them down, then tighten them down.

i have so far lol...

I guess i'm just speaking from my experience from my motorcycle...holy crap do those hex bolts strip easy!

GoldTJ 10-28-2010 08:07 PM

I have never stripped the head of any bolt,when using quality tools-EXCEPT Torx and Allen heads.Allen heads on Jap bikes are the worlds worst,and Jeep Torx are a close second,IMHO!

I have an R6 and have stripped multiple hex heads...

most recent was while getting rims powdercoated...stripped a couple that held the rotor on and stripped a couple that held the sprocket on...stupid allen heads

i always put all in and finger tighten. it just seemed as if the rear bolts would not go in as far as the ffront ones. but its probably just some dirt or something. i havent washed her in ages.
