Cool Oil pan bolt measurements?

Does anyone know the length, pitch, and diameter of standard oil pan bolts? My dealer is out and I need some today, so I plan on hitting Home Depot after work. The dealer gave me 1/4" x 280mm, 20-pitch thread. First of all, 280mm is about 11", so obviously wrong, and secondly, why would it have a standard diameter and metric length?? Anyone have the correct size and/or a part number? Thanks in advance!

By the way, this is for a '96 Tahoe with 5.7L motor.

SBC oil pan bolts have shouldered heads that help spread the clamping force over more oil pan surface for a better seal than simple hex head bolts would provide. Hex heads would :dig" into the oil pan and deform it, causing leaks. IOW, you're nuts to use anything other than bolts made for SBC oil pans.

If you can't wait for an order, ask some machine shops if they have discards. Maybe try an auto accessories shop that sells custom oil pans. Also, for some reason I thought auto parts stores sometimes carried SBC oil pan bolts. Never sought some there, though.

EDIT: or does the Tahoe's 5.7l have a thick alum pan that calls for different bolts than stamped steel pans? I'm old school.
