The DP1 screw is designed for installation into steel (up to 18 gauge and lighter), wood, and concrete substrates. When installing into steel substrates, the screw shall be long enough to show, at a minimum, (3) threads on the interior of the steel. When installing into wood or concrete, there should be at least 1” of full thread penetration into the substrate material which requires approximately 1-3/8” total fastener penetration. Installation into concrete requires pre-drilling the concrete with a 3/16” bit at least 1/4” beyond the embedment depth.
