Electric motor thru bolt (hardware)

Make one. Go to the hardware store and buy threaded rod, nuts and washers. 5 min. job and you've got bolts. For the head, jam one nut against another nut.

That's pretty much what I was going to say, but I'll add:

1. Since it's for marine use, spring the extra bucks for stainless steel.

2. On one end put a couple of nuts so you can hold it in a vice without damaging the threads. Leave a couple mm (0.1") of rod sticking up past the upper nut, and peen the end over. Now back the nut closest to the peen 'till it hits the peened end and you've got a very reliable head. Use a hand drill to rotate the rod to remove the other nut.

Go to the hardware store and buy some 10-32 all thread rod get nuts and washers to your liking and make your own bolts,with a nut and washer on each end.

Just weld the nut to the rod after you got the right langht

try Mc master Carr...www.Mcmaster.com they will most likely have what you are looking for

Best they can do is 10" then you'll have to cut it off, but as stated don't use in Marine.

OK. I see I'm not the only person in CR-4 with a degree in Af*!(@n Engineering!

What I'm looking for is a source for screws of the desired configuration. Somebody makes them and motor manufacturers use them. Where does one get them?

McMaster-Carr, do not have what I need (except stainless all-thread), and I don't want to use the all-thread.

Pull out the stops, Guys!
