Marketing InformationSAMMYS® X-PRESS® drill/drive threaded rod anchor is uniquely designed for applications where access to the back of the installed fastener is prohibited, such as metal roof decks, tubular steel or vapor barrier fabric. With the drill/drive design the drill bit is built directly into the anchor design for an even faster installation over our traditional X-PRESS® anchor. With the use of the specially designed installation tool, installation takes seconds. No retaining nut needed either.
