Abstract: Disclosed is a nail-in anchor pin setting device that is used in conjunction with a hammer to set an anchor into a surface prior to driving the setting nail thereinto to expand the anchor. The device comprises an elongated, largely cylindrical device having an impact end and a driving end. The impact end receives driving loads from a hammer, while the driving end comprises an internal bore to accept the anchor pin therethrough. The driving end is placed against the collar of the anchor while the anchor pin is accepted through the device bore. The hammer end is driven against the collar to force the anchor into a wall surface substrate, whereafter the tool can be removed from the anchor to reveal the set anchor and exposed nail pin to be driven into the anchor for expansion and securement thereof.
