Length Anchor
The length of the anchor is 9" (nine inches), and is measured as an overall length of the anchor from end to end.

The 1" x 9" (nine inches) Wedge Anchor Zinc Plated is packaged with 5 pieces per box and is packaged with the correct number and diameter of nuts and washers.

Minimum Embedment
The anchor minimum embedment into the concrete is 4-1/2". Therefore, the anchor must be installed so that a minimum of 4-1/2" of the anchor is embedded into the concrete.

Maximum Fixture Thickness
The maximum fixture thickness or the maximum thickness of the material being fastened for a 1" x 9" (nine inches) Wedge Anchor Zinc Plated is 3-1/2". This will ensure that the minimum embedment of 4-1/2" will be met.

Wrench Size
The size of the wrench required to turn the nut to set the 1" x 9" (nine inches) Wedge Anchor Zinc Plated is 1-1/2".

Torque Value
To be set properly in the concrete, the anchor must be torqued to between 250 - 300 ft./lbs.

Spacing between Anchors
Each 1" x 9" (nine inches) Wedge Anchor Zinc Plated must be spaced a minimum distance of 10" from each other when measured center to center.

Edge Distance
It is very important not to install the anchor any closer than 5" from an unsupported edge of concrete.

1" x 9" (nine inches) Wedge Anchor Zinc Plated



Installing a 1" x 9" (nine inches) Wedge Anchor Zinc Plated
  1. Drill a 1" hole into the concrete using a carbide-tipped bit that meets ANSI Standards B212.15.
  2. Drill the hole a 1/2" deeper than the anchor will penetrate the concrete, making sure the minimum embedment requirements of 4-1/2" is met.
  3. The hole can be drilled while the fixture is in place. The minimum hole in the fixture for the 1" x 9" (nine inches) Wedge Anchor Zinc Plated is 1-1/4".
  4. Clean the hole with a wire brush, vacuum, compressed air, or a blow-out bulb.
  5. Put the nut and washer on the 1" x 9" (nine inches) Wedge Anchor Zinc Plated, making sure the nut is on the last threads; this will protect the threads from damage when the wedge anchor is hammered into the hole and into the concrete.
  6. Insert the anchor through the hole in the fixture and into the hole in the base material.
  7. This should be a very tight fit. Then use a hammer to complete the installation until the nut and washer are tight against the fixture. It is important that the threads go below the surface of either the base material or the fixture.
  8. Turn the nut clockwise on the anchor until finger tight.
  9. Using a 1-1/2" wrench, turn the nut 3 to 4 times until snug or until the proper torque value of 250 - 300 ft./lbs. is reached.
  10. Always use proper personal protective equipment per manufacturer's and OSHA instructions.
