What size bolts for a winch bumper?

[Trail Ready]

I got a winch bumper but not sure what size bolts to use.What do you recommend?I want to make sure they are strong enough for the winch I know to use grade 8

Use the biggest bolt that'll fit thru the hole. I used 1/2" bolts for most of the holes. Some I had to use 7/16" bolts. Either would be plenty strong enough.

The bolt size is called a ruler?Thanks buddy im on my way down to the hardware store looking for that size.By the way,is that standard or metric?

 

[t-frady]

Grade 8 is SAE
10.9 is metric equivelent of grade 8

You're looking for a metric ruler.

I don't recall the lengths. I want to say I got 4" bolts. Not 100% sure. Don't go buying them till ya find out.

I used 1/2" on most of them. I used the stock ones on the holes that are used with a stock bumper. Then for the far back nolt I think I used 5/8th or so. And I think they were 3.5" or 4" long

Just cause I'm a nice guy and wanted to smoke a cig I walked outside, climbed under my junk, and measured the unibody at the bumper brackets. It's almost exactly 2" thick. Then assuming you have 1/4" thick bumper brackets. 3" bolts would work great.
