Metallics CSH6F Anchors 3/16 X 4 Hwh 1/4Hd Sl Blu Conc St-zn (Jar 100)

No sleeve, no shield, no setting tool. These are hex washer head concrete screws, steel with a zinc finish and a blue coating, that cut their own thread in a drilled hole. Drill, vacuum or blow the hole clean, drive it home. That also means they can be backed out and the fixture removed without destroying the hole.

At 4 inches overall, the CSH6F is built for fastening through a thick standoff, sleeper, or layered buildup into concrete or block, not for thin strap work. Subtract the thickness of what you are fastening from the 4 inches to get your embedment, and make sure the remaining length still lands in solid base material. For a strap sitting flat against the wall, a shorter 3/16 inch concrete screw is the better choice.

It has a hex washer head with a 1/4 inch hex drive, so a 1/4 inch magnetic nutsetter in an impact driver or drill runs them. The washer face spreads the load across the fixture, which is useful on strut, brackets, and sheet metal where a flat head would pull through.

No. It is a concrete screw anchor and needs solid base material, concrete, block, or brick, to develop any hold. Drywall, plaster over lath, or an empty stud bay calls for a toggle or a self drilling drywall anchor, not this part.

100 pieces per jar, packed as a jar rather than a box. That quantity suits a maintenance shop or a van stock where you want the screws kept together and recapped rather than loose in a torn carton.

The CSH6F is steel with a zinc finish plus the blue coating these concrete screws are known by, which handles interior and ordinarily damp conditions. For permanently wet exposure, coastal work, or treated lumber in contact with the fastener, specify a stainless concrete screw instead.
