The bolts do not come with the Buyers Products 2" Forged SAE Trailer King Pin with 1/2" Bolster Plate - Bolt On # 337BKPT809B.

So I did check with the manufacturer, Buyers Products, and they told me the bolts needed to be 1 inch long x 1/2 inch. As far as procedure, there isn't one I can offer as it will differ depending on the application and is a project for professional fabricators.

As for which is better, this bolt-on has the exact same specs as the weld-on # 337KP20050 king pin so their quality is equal.
