  • Page 12: Why A Fastener Holds

    Why A Power Fastener Holds WHY A POWER FASTENER HOLDS IN CONCRETE The compression bond of the concrete to the power fastener accounts for the majority of the holding power. The fastener dis- places the concrete which tries to return to its original form causing a squeezing effect.

  • Page 13: Selecting Fasteners And Power Loads

    Selecting Power Fasteners and Power Loads FASTENING INTO CONCRETE The proper power fastener length can be determined by adding the thickness of the material to be fastened and the amount of fastener that will actually penetrate the concrete. The concrete must be three times as thick as the intended fastener penetration.

  • Page 14: Operation

    Operation Grasp muzzle and slide barrel forward rapidly until it stops. This sets piston into firing position and opens the chamber. 482-70 Insert power fastener into muzzle of tool, head end first. Push the fastener until point is even with end of tool. ALWAYS load the fastener first, then the power load. 482-71 Select the proper Remington Power Load and insert into the chamber until it stops (see Application Chart on page 23).
  • Page 15 Place the muzzle of tool perpendicular to work surface without tilting the tool. Push tool against work surface until sliding action of barrel stops.
