5/16-18 x 3/4" round head square neck carriage bolts in 18-8 stainless steel to ASME B18.5, plastisol under head finish. A smooth domed head with no drive and a square neck that locks into the hole so the nut can be tightened from one side. A plastisol (PVC) coating under the head seals and cushions the bearing surface against the work. Sold in production-volume bulk packs.
