Blue Slotted Hex Washer-Head Concrete Screw Anchors

Blue slotted hex washer-head concrete screw anchors are mechanical fasteners used to secure fixtures to concrete and compatible masonry substrates. Their combination of a hexagonal washer head and a slotted drive distinguishes them from countersunk concrete screws and anchors with other head configurations. The hexagonal head allows tightening with a wrench or socket, while the integrated bearing flange distributes contact against the mounted fixture.

These anchors use specialized threads that engage the base material through a predrilled hole. Common applications include fixing metal brackets, electrical fixtures, cable clips, door tracks, and other hardware to concrete or suitable masonry. Their protruding washer head is useful when the fixture does not require a flush mounting surface.

When selecting an anchor, consider the nominal diameter, length, head dimensions, compatible base material, and required embedment depth. Hole diameter and drilling depth must follow the specifications for the particular anchor. Blue coating identifies the finish appearance, but its composition and corrosion resistance depend on the coating system. Dimensions and load performance should be confirmed against the applicable product specifications rather than assumed to be interchangeable across different concrete screw designs.
