I dunno . . . .

Sorry. I just went down to the hardware superstore, the "fastener guru" measured the lenght, threads, and pitch, and gave me the next shortest matching screw. Worked like a charm.

Of course, this hardware store had a jillion stainless steel screws to choose from. You may be better off taking the advice from Savage Parts, above.
