T toolmakerprevo Getting the Wheeling Fever Quote Quote And always use grade 8 mounting hardware. That's what I always thought until my friend gave me a Warn 8274 that was on a truck he just sold. I just bought a Warn mounting kit so I can mount the 8274 on my 80 CJ-5 and am surprised that the winch plate is basically held to the Jeep by 4 grade 5 7/16" UNC carriage bolts. <img src="/forums/images/graemlins/rolleyes.gif" alt="" /> ANSI Standard grade 8 bolts are the only way to go. Some machine tool purchasers mandate grade 8 screws in all assemblies, Grade 5 is a bean counter at warn saving 0.3 cents per bolt over 10,000 units sold!

I tend toward over engineering bolts also...however the shear of 4 7/16" bolts is enormous compared to the tug of the winch. Common no. 5 bolts are holding most of the winches in this country as I type... Did anyone EVER hear of a winch popping all 4 bolts? Didn't think so.. If the winch came with bolts...use em is my advice..

Thats what I thought about doing until I started looking for 7/16 grade 8 carriage bolts. None to be found around here. Oh well, as Big Jim said, nothing wrong with using the supplied hardware. <img src="/forums/images/graemlins/kewl.gif" alt="" /> Last edited by 80CJ; 01/22/08 09:19 PM.

I had these two tow hooks that I've been wanting to mount on the front of the Jeep for a long time. I ended up enlargening the front hole on the winch mount to accept a 1/2" bolt and drilled another hole to accomodate the rear tow hook hole. The hardest part was filing the holes square in the frame mount as those are square necked grade 5 carriage bolts.
