Stainless Bolt

Can anyone help, I need a 3.5 inch 7/16 UNC bolt to bolt the sacrificial anode to my CLE box from underneath . Does anyone know where I can get one ? I've tried locally without success.

isn't it either countersunk or a cap head rather than just a normal bolt?

I thought it should have been, but the sacrificial diode wasn't countersunk and it came with a normal bolt thats about 2" short. It was the only one we could find without a fin on the Merc parts website.

the first pic is standard with the thread in the anode so it bolts down through from inside the leg. The bolt is 45mm long
the second pic is modified to accept the socket head bolt and to bolt up through so as to avoid putting your hand in the exhaust again the bolt is only 50mm long

Hi Burty I've got the 1st one. But the bolt is too short as I have to go from underneath and the thread only goes a short way into the leg. Theres definately no hole from the top I checked again today. So I'll just get a 3inch bolt and try to recess it into the anode .

the second pic is a modified one with the bolt recessed into the anode but again the bolt is only 50mm long
I'm pretty sure its just an M10 socket cap bolt and you just tap the hole in the leg to suit
