This fastener system can be installed pneumatically with the FastenMaster TigerClaw Gun or by using a drill. Other Features: CONCEALoc® Hidden Fasteners can be used on angles up to 45 degrees. On angles, offset the center of the fastener 1/2’’ towards the long point of the joist so the screw will not exit the side of the joist when driven CONCEALoc® Hidden Fasteners provide consistent spacing between the sides of boards but deck spacers can be used in combination.
