Brand Name CONFAST

The anchor is made from Carbon Steel, and is Zinc Plated. This anchor is designed for use in Concrete, Block, and Brick.

The anchor is designed for use in a Dry environment.

Head Style
The anchor is a Acorn/Open head and is designed to allow the head to sit on top of the surface of the item being attached.

Hole Diameter/Bit Diameter
The anchor requires a 1/4" 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.

Diameter of Anchor
The diameter of the anchor is 1/4".

Length Anchor
The length of the anchor is 5/8"

Thread Type
The threads on the anchor are national coarse threads that measures 1/4" with 24 threads per inch, commonly referred to as 1/4"-24 .

The anchor is packaged with 100 pieces per box and comes assembled with open acorn nut and washer.

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

Depth of Hole
The depth of the hole that is required for the anchor should be a minimum of 1/2" deeper than the anchor will penetrate the concrete. This will allow space for dust created during the installation process to fall, which will prevent the anchor from bottoming out in the hole before full penetration into the concrete.

Maximum Fixture Thickness
The maximum fixture thickness or the maximum thickness of the material being fastened for a anchor is 1/8". This will ensure that the minimum embedment of 1/2" will be met.

Fixture Hole Diameter
The hole in the fixture or material being fastened must be larger than the designated diameter of the anchor. The 1/4" diameter anchor requires the hole in the fixture to be 5/16".

Wrench Size
The size of the wrench required to turn the nut to set the anchor is 7/16".

Torque Value
To be set properly in the concrete, the anchor must be torqued to between 2 - 6 ft./lbs.

Spacing between Anchors
Each anchor must be spaced a minimum distance of 2-1/2" from each other when measured center to center.

Edge Distance
It is very important not to install the anchor any closer than 1-1/4" from an unsupported edge of the concrete.

Installing a 1/4" x 5/8" Acorn Sleeve Anchor Zinc Plated
  1. Drill a 1/4" 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 1/2" is met.
  3. The hole can be drilled while the fixture is in place. The minimum hole in the fixture for the 1/4" x 5/8" Acorn Sleeve Anchor Zinc Plated is 5/16".
  4. Clean the hole with a wire brush, vacuum, compressed air, or a blow-out bulb.
  5. Put the nut and washer on the 1/4" x 5/8" Acorn Sleeve 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 until the nut and washer are tight against the fixture.
  7. Using a properly sized hammer for the 1/4" x 5/8" Acorn Sleeve Anchor Zinc Plated, set the pin with a number of square and sharp strikes to the head of the pin until the pin is flush with the top of the anchor. There is no need to torque the nut to set the anchor since the anchor is set with the correct set pin.
  8. Always use proper personal protective equipment per manufacturer's and OSHA instructions.
