This is a multi-purpose stud from GM, factory part number 3814692. It is catalogued under Bolts & Screws > Studs.
Keeping the old part until the new one is fitted and checked is the simplest way to avoid a second order.
The part number is the thing to verify. Where the old part carries no legible number, a VIN and a photograph are enough for us to identify it. Leaves our US warehouse in one to two business days, and shipping is free over $59.
