The anchor is made from Carbon Steel, and is zinc plate. This anchor is designed for use in Concrete
The anchor is designed for use in a dry environment.
The anchor is a Mushroom Head 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). 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".
The length of the anchor is 4"
The minimum anchor embedment into the concrete is 1-1/4". Therefore, the anchor must be installed so that a minimum of 1-1/4" 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 2-3/4". This will ensure that the minimum embedment of 1-1/4" 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".
Spacing between Anchors
Each anchor must be spaced a minimum distance of 2-1/2" from each other when measured center to center.
It is very important not to install the anchor any closer than 1-1/4" from an unsupported edge of the concrete.
1/4" x 4"
Installation Procedure Drill a hole into the base material to a depth of at least 1/2" deeper than the embedment required. The tolerances of the drill bit used should meet the requirements of ANSI Standard B212.15. Blow the hole clean of dust and other material.
Where a fixture is used, drive the anchor through the fixture into the anchor hole until the head is firmly seated against the fixture. Be sure the anchor is driven to the required embedment depth.
