RED-Z06 2,221 #1 Posted December 20, 2021 Mine had no hardware, it looks like 5/16-18 x 3/4 on the seat bracket (4) and the others 5/16-18 x 1/2? The gas tank is like right there in back... 1 Share this post Link to post Share on other sites

And I always use washers too, but that doesn't take much length off. 2 Share this post Link to post Share on other sites

Yes, they do. I just did mine and stuck my caliper down the hole to measure. I don't recall the exact depth but it was at least an inch. I used 1" bolts with a flat and a lock on all of them. 2 1 Share this post Link to post Share on other sites

pacer 3,169 #8 Posted December 20, 2021 A little bit OT, but have you guys ever tried "flange head" bolts/nuts? I picked up a Massey garden tractor and apparently they used ALL flange heads thru out and I have fallen in love with them. I even went over to my bolt place and bought a bucketful of assorted sizes. Eliminates need for lock washers.... 4 Share this post Link to post Share on other sites

Especially when the holes are slots or just wallowed out from age... 2 Share this post Link to post Share on other sites

I consider them for something that goes together and stays together. And they sure will mess up some paint too. Much more so than a flat washer with a lock washer would!

pacer 3,169 #13 Posted December 20, 2021 Like many things, the serrated bolts have a place among all the other hardware. On the Massey I mentioned there was a mix of different bolt types. While I was aware of them, I just had never used them other than occasionally and when I took the MF apart and reassembled it I became impressed with them.

They'll chew those up and spit them out! For that application a toothed washer is 'on call'. Edited December 20, 2021 by Jeff-C175 1 Share this post Link to post Share on other sites
