Radiator mounting set screws / bolts ?

[DavePoth]

The ones that connect the radiator to the bracket. Any ideas on a size for them? I think they're 1/4" UNF but I'm unsure on the length since I've now lost them.

They are sort of special with a spiral cut down the threads to ease removal in rust and not bind on the captive nuts.

Try Ficthetts....

They also have a pointy end to help location in the captive nuts.
Try 519040 for a 1500, SH605081 for an 1850 and HU807D for the Sprint. The Sprint also has spring washers.

Ha...fancy the Sprint and 1850 having different p/n's for the same thing.

Only the rad core is a bit beefier on a Sprint. The bracketry is the same...

The design of the bolts is primarily designed to aid assembly when the captive nuts are full of paint on the line. When restoring you have more time to tap out the threads and normal bolts can be used.

The question is about the bolts that hold the radiator within its brackets.

These are 1/4" UNF set screws.
When I needed these previously, I got the shortest I could find then cut them down to a suitable length.

As they are flared, the heads on OE set screws have a smaller socket size than the usual, but the normal head type in conjunction with spring washers work fine.

Ah yes ! Sorry about that.
I was always told at school to read the question properly before answering.

Cheers for that. I guess they need to be about half an inch long or so when cut down?

I used these with a spring and flat washer (and a bit of copper grease).
