Applications
The 1/2" (two inches) Single Expansion Anchor is made from Zamac . This anchor is designed for use in concrete, block, and brick.

Environment
The anchor is designed for use in an outdoor, moist environment.

Hole Diameter/Bit Diameter
The 1/2" (two inches) Single Expansion Anchor requires a 7/8" hole to be drilled in the base material (concrete, block, and brick). The hole should be drilled with carbide tipped bit that meets ANSI standards and used in a hammer drill.

Designated Size
The designated size of the anchor refers to the inside diameter 1/2" of the anchor or the diameter of the threaded rod or bolt that can be inserted into it.

Diameter of Anchor
The diameter of the 1/2" (two inches) Single Expansion Anchor is 1/2".

Length Anchor
The length of the anchor is 2" (two inches), and is measured as an overall length of the anchor from end to end.

Thread Type
The threads on the 1/2" (two inches) Single Expansion Anchor are national coarse threads that measures 1/2" with 13 threads per inch, commonly referred to as 1/2"-13.

Packaging
The anchor is packaged with 25 pieces per box.

Minimum Embedment
The 1/2" (two inches) Single Expansion Anchor minimum embedment into the concrete is 2". Therefore, the 1/2" (two inches) Single Expansion Anchor must be installed so that a minimum of 2" of the anchor is embedded into the concrete.

Fixture Hole Diameter
The hole in the fixture or material being fastened must be larger than the designated diameter of the anchor . The 1/2" diameter anchor requires the hole in the fixture to be 1".

Torque Value
The maximum torque that can be applied to the 1/2" (two inches) Single Expansion Anchor once installed is 20 ft. lbs.

Spacing between Anchors
Each anchor must be spaced a minimum distance of 8-3/4" from each other when measured center to center.

Edge Distance
It is very important not to install the 1/2" (two inches) Single Expansion Anchor any closer than 4-3/8" from an unsupported edge of concrete.

Bolt Length
When a bolt is used in conjunction with the anchor , the length of the bolt needed is determined by considering these factors:

  • Flush With Concrete - when the anchor is set flush with the surface of the concrete, add the thickness of the material being fastened to the thread and then add the space for any washers used.
  • Below Surface of Concrete - add the depth below the surface of the concrete to the thickness of the material being fastened, then add the space for the washer, and, finally, add for the thread engagement.

  3. Clean the hole with a wire brush, vacuum, compressed air, or a blow-out bulb.
  4. Insert the anchor with its threaded end first into the hole.
  5. Place the fixture over the 1/2" (two inches) Single Expansion Anchor, insert a 1/2" diameter bolt through the fixture and into the 1/2" (two inches) Single Expansion Anchor.
