They are made of 300 series stainless steel top specially fused with a carbon steel bottom, then coated with Stalgard® for corrosion resistance and installation efficiency. Visually the Aggre-Gator® looks like the Crete-Flex®and not an Ultracon.

Crete-Flex® is a concrete screw made with the legendary Flex technology using 410 stainless steel for fantastic shear values. A Crete-Flex fastener doesn't look like an Ultracon visually. If you don't need the Flex technology, Ultracon comes in 410 stainless steel as well.
