Starter bolts

[Edbert]

I know, I'm an idiot for losing them, as well as lazy for not trying out a hundred or so of the ones in the big box-o-spare-bolts, so spare me the comments please

Does anyone know the size of the bolts that hold on the starter motor for a Windsor engine?

I think there 5/16x1-1/4

Nope. they're 3/8"x 1-1/4. They have 1/2" heads.

I'm going down to the local home-improvement warehouse to look through their grade-8 bins (I know those are overkill but don't care). Do you happen to know the thread pitch? SHould I use lock washers or flats or both?

Also, this is for a 351W, they are the same as the 289/302/5.0 right?

Threads are NC ( National Course) Lock washers, definately. All small blocks used the same starter bolts.

The set I bought fit fine, thanks guys!

FWIW, the labeling called the thread pitch a "16", which I think means 16 per inch.

Also, to flesh out the tech here...do Clevelands and FEs use the same starter bolts?

 

[D.Hearne]

Not sure, but I believe the FE bolts are 5/16NC.
