the bolts on my cat with the spring is rounded, im gonna cut the bolt in half
but before i do that i want to know how long the bolt is so i can replace it

does anyone know the length ?? also i was at the local hardware store and they have grade5 and grade8 bolts
which grade is good for the cat or does it not matter ??

thanx in advance

 

I just bought some cheap bolts, nuts and washers from Home depot. Just reuse the spring from the spring bolts.

I got ones that were a bit longer than I thought (just to be safe) and threaded completely so I didnt really even have to measure. They're probably like 3.5" long. Working fine since last summer.

 

the only problem is the bolts at our hardware store dont have the fully threated ones
they only have the 1/4 thread style ones

my geusses were around 3.5-4inches in legth

but i was hoping for some confirmation, thanx for the info man

 

confirmation from anyone ??

 

cat what cat run straight pipe

 

well yes i am using a test pipe but i figure "cat bolt" is more understandable compared to "test pipe bolt"

 

The threaded portion of the bolt is 8mm
so that or a 5/16" would probably work.

Overall length including the head is 70mm.
Here is a pic for reference:

 

Be carefull when you cut the bolt! My friend almost had his eye taken out cutting the bolts on my del sol. THe bolt just missed his head and left a dent in my frame!!1

 

thanx guys you rock
