Stock Bronco nuts, bolts, and screws thread

Post by akaFrankCastle »

Okay, there have been several threads over the years about what size bolts, what thread pitch, what length, etc. are needed for specific stock Bronco applications. I thought, "Hey, why not a sticky for all of those ankle biter type questions?". So, here it is. How about we keep it short, simple, and to the point. If you have a stock application, or common mod application, bolt, nut, or screw that you are trying to find, let's throw them up in here and see if we can't get a little single point of reference for all of those hardware questions everyone seems to have. Sound good?

This thread couldn't be more timely, Big O is a ground up build, every bolt and nut has been removed. I'll try and get a list going of what we've done so far, but may just jump in at the current build point.

Looking for bolt and nut sizes for leaf spring bushing and hanger hardware. Swapping new springs into Stroppe'd and Old stuff is moving to Project X. Only have one set of hardware so I'm gonna run to the Depot.
