Will this hinge work with my factory hood latch?

Yes. This hinge is designed to mate with the OEM latch mechanism without modification. The geometry matches factory specs, so your existing latch will engage and release normally.

Do I need hood pins or a secondary latch with this hinge?

Hood pins are not required by the hinge itself — they're optional based on your driving needs or preference. The factory latch provides normal retention on its own.

What fasteners do I use to mount this?

Use the bolts that came with your original hinge, or source OEM bolts to match. Torque spec depends on your vehicle's service manual — don't overtighten, as the mounting ears can crack.
