If that is zee bolt you pulled oot. then that is what it is. should be a Grade 8 bolt though. k:k:k:k:k:k:

 

ahh, the wisdom of PS93 :grin: It was actually a 3/8-24. My question is really what makes it "special" There are other bolts the use loctite, why is this one called out?
.

 

Grade 8 Bolts have the highest tensile breakage point of them all. that is what that bolt was spec'ed at. When it left the Little TORO Factory Here. you don't want anything to break on you when you are going FULL BORE on in the BIG ******. Now do you?????? :smiley-think001::smiley-think001::icon-doh::icon-doh::icon-doh:

 

hmm. the one I took out was grade 5 bolt. Do you have a torque spec for this? I could not find one, only for the cylinder cover bolts.

Thanks.

 

I don't think it's all that "special".

Is it all threads (no shank). If I were to make a guess at what makes it special, it would be the shank-to-thread ratio.

 

My new guess is it may be the pre-applied thread locker. If it were me....I wouldn't hesitate to get an off the shelf bolt.

Here is a link to one (with photo) for anyone that wants to add their opinion.

yeah DBert, that is the only supplier picture with an image. On mine, it is not all threads, about 1/4 of the length is not threaded. I'm thinking the pre-applied loctite is the "special" part too. Note that I am not worried about this part, just inquisitive about it.

 

Understood. I appreciate you pointing it out. Being labeled as "special" that is.
As for the torque value, when all else fails there is always the ole "standard" torque values.
