Wheel Stud Load Ratings

[Toolingtek]

When testing the shear strength of a automotive wheel stud fastner would the shear strength rating (128 KSI) be along the center axis. Is it a pull type test along the stud center line axis until it pulls in half?

If you are pulling along the center line axis you testing tensile strength. Shear strength is measured perpendicular to the center line axis.

Thanks, should have thought longer, long day. Yes shear / shearing action normal to C/L...Ultimate tensile measured through C/L.
