Where do you get your screw needs?

Qomomoko · February 16th, 2015, 02:38 PM

due to my attempt to mod my ninja 250, I am in need of grade 8 M12 in 120mm length with the finer the pitch the better.

It appears they are hard to find even on line from my recent search.

I ,after a wasted trip to a small store ( in the Miami Area) where the guys told me he had the M12 grade 8 only for it to be grade 8.8, am wondering what you guys do to satisfy your strong bolt needs?

Mitch's Welding has usually had what I need but he does not carry grade 8 nor 10.9 (also Miami)

Miami Welding | Miami Welders | MitchellsMiami.com | Miami Welding Machine Fasters

gonna try later this week (also Miami area) this place below in Medley (gosh I hate the traffic) where I might find what I am looking for but can not be certain until the goose is cooked.

i tried a couple online but the 120mm M12 appears to be a rare diamond for my search abilities.

This is for those of you in the Miami Area for local stores or for you'all then online sources

there is no grade 8 in metric. It's 8.8 (gr 5), 10.8 (gr 8) 12.8 (gr 9) the relationship to SAE grade isn an "ish" measurement. It's not an exact 1 for 1 swap.

in 12mm you can have 1.75 thread in a 10.8 or 1.25 thread in an 8.8
both are available from McMaster.com

AWESOME!!! yes

i'll go with the 10.8 minimum,, to be safe as I can not tell what grade the stock ones are, can you?

its for making my rear shock linkage wider to fit a wider spring from an 05/06 GXSR 1000

those appear to be non standard markings. It may be something Kawi did so the people on the line knew. Bolt #7, #8, #9 goes in which holes. With no obvious marking, and being used in double shear. I'd go with a commonly available 8.8

I also made a mistake in the above post. SAE gr8 is about equal to Metric 10.9

edit;
something more important than the bolt grade you need to consider.
Find a bolt long enough that all of the loads will be on the shoulder not the threads. That will increase the strength even more. If you need a 200mm bolt to achieve this just cut the end off after you put the nut on.

dang i already placed the order and they had full thread only, did not think about getting longer and then cutting in case that was available for the bolt shoulder.

but even with a screw with a bolt head side with a shoulder, on the other end where the nut goes, that side dogbone would still be resting on threads... so not sure how to avoid having dogbones not rest on threads but what you say makes sense.

AwDang · February 16th, 2015, 05:11 PM

a thread in the end of the nut side leg isnt a deal breaker. In an ideal world all the load would be on the shoulder and you'd have a washer to space the nut to the threads.

Stock is a JIS 7, which is equivalent to a 8.8 in the ISO metric system.

Take a look at this:

It is important to fit as much of the cylindrical neck (rather than the threaded section) into the holes in the chassis as possible.

fastenal is pretty good, usually gets to me in 2-3 days and you can buy bolts by the each.

i always try to buy this stuff local, but lately the hardware stores just stock a bunch of china junk, if they stock anything at all... lowes and home cheapo are worthless. if you can find an old school hardware store, you're lucky.
