Dorman Bolt P/N:980-320D
Dorman 960-320D bolt is a Grade 8 hex bolt that clamps parts together with a coarse thread. The pack holds three 7/16-14 x 2 in. bolts.
A rounded hex head, damaged threads or heavy rust can mean a bolt is due for replacement. These signs alone do not prove the bolt is the problem, since a stripped hole it threads into can loosen a joint just as well.
This is universal hardware, sold by size and thread rather than by application. Match the thread size, length and hex head to the bolt you are replacing; the numbers are in the Specifications list.
