Well i have pulled out one side of my cars body bolts (for body lift)and iam wondering where i can get hi tensile bolts?

-i have seen hi tensile bolts for sale in bunnings, are these strong enough?

-and how much (approx) should each bolt cost? casue the bunnings ones go for round $2 each

Cheers

high tensile bolts should have a grade stamped on the bolt head. Mild steel is grade 4.6, I think most high tensile bolts are 8.8 although I have seen 6.8. shackle bolts may be higher than 8.8, I'm not sure.
8.8s would be fine for what you are doing I imagine, they are a very strong bolt.

Be carefull of bunnings they only stock campion packets of high tensile bolts.
My suggestion is to use the yellow pages and look under fastners it should'nt cost mor than $30 from a bolts and bearing shop

If you had a Blackwoods industrial store somewhere near you, they will have them.

Any bolt stores have em, biggest one that comes to mind is Coventry Fasteners, then theres others which are propably not franchises so only in one location like Ajax Fasteners, Melbourne Bolt, etc...

definantly dont go to bunnings

90% sure they wont have the exact bolts you want.

A fastener place is where you wanna go. There is several in MOSS street area, but i dont know where any are down the coast.

The standard Paj bolts are a metric fine, so you'll have trouble finding longer bolts to fit the factory nuts - buy new nuts, too.

The original bolts also have unusual heads, which effectively produce a larger surface area. Buy some mudguard washers while you're out.

It's unlikely you'll find what you need on a Sunday.

Good luck,

Scott

thanks for your replies. ive had a look the bolts have a 7 stamped on them.

ill be heading off to a fastner shop during the week to get some longer bolts (8.8)and nylock nuts

Look up "bolt shop" on www.whitepages.com.au you should find what you're looking for there.

That is a common number to be stamped on Japanese vehicle bolts. They use a different scale to grade their bolts. Usually 4 or 7 on most of their bolts. Im sorry i dont know what the 7 is equivilant to though.

yeah its a bit random. 4 of the 6 bolts have 7 stamped on them the other 2 have an 11 stamped on, and the haynes manual dosent say what thatey mean, so im just going to get 8.8 bolts

if you're on the Gold Coast, try these for propper nuts and bolts.

if the bolt does not have 8.8 stamped on it look for 6 diaganal lines in the top of the bolt, this also means 8.8 grade

nah it dosent have any lines, just the number stamped on. The haynes maunal dosent have a thing on it.

thanks ausoops and roctoy, ill go and have a look this weekend when im back down on the coast

the guys at the fasteners shop will be able to tell you what grade it is.

NO it doesn"t - this is a common misconception.

GRADE 5 (UNF etc) = 3 radial lines and is equivalent to CLASS 8.8 Metric
GRADE 8 (UNF etc) = 6 radial lines and is equivalent to CLASS 10.9 Metric
btw - a Pajero has metric bolts and the GRADE MARKINGS/LINES will NEVER be on METRIC bolts.

NCpaj - what you have are bolts with the standard Japanese automotive marking system - but I am not 100% sure what the numbers mean.

Grade 5

These are medium-carbon steel fasteners that have been heat-treated, quenched and then tempered to achieve a level of tensile strength and hardness that meet the requirements for a wide range of automotive and mechanical assemblies. Identified by three radial lines and the manufacturer’s head marking, Grade 5 fasteners are specified by automotive and equipment manufacturers for general applications where moderate strength is required. Traceability is required for Grade 5 fasteners.
Grade 8

ROCKFORD® Grade 8 fasteners, which meet the highest SAE specification for fasteners, are required for critical automotive fastening applications such as flywheels, universal joints, transmission mounts and cases, motor supports, front end suspensions, mounting fifth wheels, and similar high-load potentials. They are identified by six equally spaced radial lines, and the manufacturer’s head marking is required for traceability.
Property Class 8.8 metric

Comparable to SAE Grade 5, these cap screws are manufactured from medium-carbon steel, then heat-treated, quenched, and tempered. The numbers 8.8 on the head along with a manufacturer’s logo or head mark identifies them. Property Class 8.8 fasteners are specified by both foreign and domestic automotive and equipment manufacturers for use in a wide range of applications where moderate strength is required. Traceability is required for this class of fasteners.
Property Class 10.9 metric

Comparable to SAE Grade 8, these cap screws are manufactured from medium-carbon steel, then heat-treated, quenched, and tempered. The numbers 10.9 on the head along with a manufacturer’s logo or head mark identifies them. They are specified in critical automotive and heavy-duty applications with high-load potentials. Traceability is required for this class of fasteners.

Yes but that is the same on all vehicles???

At least it isn't as bad as Land-Rover - they gradually changed from imperial to metric over about 5 years (as they ran out of bolt stockpiles). During that time they produced vehicles with a mix of both ...

Don't know - only tried to replace one once, and I just presumed it was metric. I was wrong. Again.

The numbers on Jap auto bolts refers to the torque settings of them in the workshop manuals for that particular vehicle.

i.e: All bolts with a 7 on them = tighten to 100Nm etc. (just an example not spec.)
