These features provide Crete-Flex screw anchors with exceptionally high mechanical strengths. For every project, it is important to consider several things before making a selection: The proper head style, the color or finish that is desired, and the required level of corrosion resistance. The Crete-Flex screw anchor is available in 410 stainless steel. Head styles include a hex washer, hex flange, phillips flat and phillips trimfit.
