5.0 out of 5 starsJeep Wrangler TJ (1997-2006) Front Bumper Bolts
By Pachyderm on October 12, 2015
Thread Size: 1/2"-13Thread Coverage: Fully ThreadedFastener Size: #10-12Number of Items: 10Overall Length: 1-1/2
Replacing the T-55 Torx bolts on my 2003 Jeep Wrangler front bumper. I posted this review mainly so that the exact size would be visible for any other Wrangler owners who stumble in here looking for the same sort of replacement bolts. These are 1.5" long and fit the two bottom holes as well as the four top holes if you do not have tow hooks or a brush guard or anything else that would require a longer bolt. If you have the Mopar OEM tow hooks the four on the top are (I think) one inch longer. I purchased a front bumper with D ring mount points, so I decided that the tow hooks can go bye-bye now; I am returning to the shorter bolts and streamlining the front of the TJ a bit.

I *hate* those T-55 Torx bolts. Getting some good Grade 8 hex heads in their place will make me happy.
