Tractor supply G8 bolts
 

what say you on tractor supply grade 8 bolts ??? why am i asking.. will these days who knows anymore what you get .....
they might say grade 8 but it isnt the 60s no more ..

...I have used the Grade 8 hardware from Tractor Supply with no issues...I also used Fastenal products with good results.

I love tractor supply when it comes to bolts. It's the cheapest place when they sell them by the pound. Just understand that you shouldn't always use grade 8 bolts thinking that they are better. They aren't better in all situations. Grade 8 is harder, but they can also break easier depending where the stress loads are for that bolt. It's like using nails for framing a house instead of screws. Nails will flex when the structure moves, screws will just snap off. Same thing can happen if you use too hard of a bolt.

goin to replace the side plate bolts on a k12hp. maybe ill get 5s. have to check the manual ...

but good to hear from both .. there ok bolts..
had gotten bolts from local hardware store for the pickum up truck muffle and they broke rite off lol the head pulled from the shaft of the bolt like a air pocket was in there.
so was just makin sure lol ..

ty ty for info

"side plate bolts"??!!
I give up, WTH are they and why do you want to replace them????

It may mean the closure plate on the flywheel side.

I'm at a loss as to why anyone would want to replace those bolts.
Head bolts, yes

maybe theres one missing from someone who needed one or a failed rebuild.
maybe the block i have is missing one..

the bearing plate from the block was used somewhere else and they lost a bolt from the block and didnt replace it..

maybe someone over tighten one and broke it off. i get the block and have to replace it..

maybe someone not knowing motors tryin to learn and was told one thing and it wasnt rite. so block was good but they took it apart and lost bolts. they gave up maybe ..

many many reasons..

for me... i like to have xtras of things. bein prepaired and ready for anything.

anyways thank you all for info..
think ill grab some 5s and some 8s then i have them..

Grade 5 bolts are plenty strong.Use grade 8 on head bolts.Don't over think it.Check the torque to break a 5/16 bolt for instance on a chart.You will be surprised.

I am with you on that. I live too far away from town so my shop is like a hardware store. I try to keep things I might need to keep from making a special trip to town.
