8.8Grade HDG Hex Bolts and Hex Nuts(DIN933 AND DIN934):
Hex Bolt, Heavy hex bolt, 8.8grade Hex bolt, 4.8grad hex bolt, HDG hex bolt

Commonly called hex head cap screws, are bolts with a hexagonal or six sided head. A hex cap screw is actually manufactured with tighter tolerances and can be used anywhere a hex bolt is used. A common feature on a hex cap screw is a washer surface directly under the head which creates a better seal.
