like midlifer... i bought most of my ss bolts from boltdepot.com and saved a bunch over buying local
boxes of 100 nuts, bolts and washers cost me a lot less than the kits of 66 bolts from vendors
i used ss
truss head bolts for fender bolts. big headed phillips head bolts
buy as many as you can at one time, shipping can eat you alive if you forget this and that
home depot is getting a better selection of grade 8, grade 5 and ss bolts for those occasional purchases
i didn't track how many trips or my cost of hardware from home depot, i shudder at the thought
