ok i went to the hardware store to find a really strong bolt for my shockmount. its a half inch steel shock mount but its only one sided. and i need to know how strong a course 5 bolt is ?

**300ex4wheel** · 06-30-2003, 03:59 PM

depending on the grade of bolt. grade 8 is the strongest, a grade 8 has 5 or 6 lines on the top of the head

ok but why does it say course 5 bolt where i purchased it?? and i just looked at my bolt it has 3 lines on top of the head. would it be strong enought for the landings???

THe bolt you have is a Grade 5 it's not the strongest bolt out there.
Stick with Grade 8 bolts and nuttin less

course refers to the threads, they are wide spaced instead of fine threads, which are like your wheel studs

5 is grade 5 which has 3 lines on top, grade 8 has 6 lines on top which is the strongest of the two

yeah 8 is the strongest
