Metal Hit Anchors

Metal Hit Anchor Installation

There are four simple steps involved in installing a metal hit anchor. Concrete metal hit anchors are most commonly used with concrete, brick and block, light to medium duty. These anchors are temper proof. Nail anchors should not be used in overhead applications. Metal hit anchors combine toughness and strength for precision.

1. Drill hole in masonry or concrete through mounting holes in fixture same diameter as anchor to be used. In wood and other soft material to be used, drill through fixture and directly into masonry. (drill hole 1/4" deeper than the calculated embedment depth.)*

2. Insert anchor assembly through mounting holes in fixture and into anchor hole.

3. Tap gently until head of anchor body is set tightly against item to be fastened.

4. Gently hammer pin flush to expand body. Do not over drive pin as the could damage the anchor.

* Always wear safety glasses. Follow the drill manufacturer's safety instructions. Use only solid carbide-tipped drill bits meeting ANSI B212.15 diameter standards.

* Take a look at the metal hit anchors available from Hilti.

Metal Hit Anchor Detailed Installation Directions

The hammer drive anchor is designed for use in the following materials: concrete, brick or block. When working with these anchors, the required hole size is always equal to the anchor size. For example, a 1/4” metal hit anchor requires a 1/4” hole. To determine the length of the hammer drive anchor, add the thickness of the material to be fastened plus 1”. Once the required length and hole size have been determined, drilling can commence.

When fastening to concrete, brick or block- a hole needs to be drilled into the base material. Use a hammer to drill the best quality hole. Once the bit is chucked into the hammer drill, the depth of the hole to be drilled can easily be set by using the depth gauge on the hammer drill or by wrapping the bit with tape at the required depth. Before using your hammer drill- make sure that you use ear/eye protection and that the drill is in hammer mode. Drill into the base material until you reach the required hole depth for the anchors.You can tell you have reached this depth using the drill gauge or the tape you wrapped around the drill bit. The hole must be cleaned of all concrete dust to ensure proper fastening. Using a wire brush and a vacuum or compressed air will ensure that the hole is cleaned out properly. Place the fixture over the hole making sure that the hole in the fixture is large enough to allow the hammer drive anchor to be inserted through it. Insert the hammer drive anchor through the hole in the fixture and into the hole drilled in the concrete. Set it flush so that the head of the anchor touches the fixture. Take your hammer and drive the nail into the anchor until the head of the nail is flush with the head of the anchor.
