Grade 5 Pin Hardware
(OP)
Greetings,
I have an application in which the shank or unthreaded portion of a Gr5 3/8" bolt is used as a pin for a member to rotate about. Well the design has changed so that the bolt has shortened (~3/4") and most bolts of this shorter length are fully threaded. Like I said it is a pin application and sees mostly shear so maybe the clamping force a bolt provides isn't needed at all. Although the application does require the strength that a Gr5 bolt offers.
I'm thinking of a 3/8" clevis type pin with the strength of Gr5 Hardware and some sort of external retaining ring.
But then again I might not be able to find the length I need off-the-shelf. So perhaps obtaining a high strength rod and turning it in-house might be the solution unless machinability and tooling issues occur.
Any suggustions appreciated

Unclesyd,
I search all of my hardware from Mcmaster.com well just because Im unseasoned. I found a metric equivalent of class 12.9. Aware of any other extensive hardware dealers?
I've also seen situations where the threaded portion of a screw is used as the pinned surface. For fear of galling that would be my last choice even though it's steel on steel. Any thoughts

Here is every thing I think you can find in the way of pivot pins.
I think all these pins, except SS, would be equal to or better than the Grade 5 material you require.
