The anchor is made from Hardened Carbon SteelBlue Rusper. 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 Hex Washer Serrated 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 3/8" 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.

Driver Required
A 9/16" is required for driving the anchor into the base material.

Diameter of Anchor
The diameter of the anchor is 3/8".

Length Anchor
The length of the anchor is 3"

The anchor is packaged with 50 pieces per box .

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

Wrench Size
The size of the wrench required to turn the nut to set the anchor is 9/16".

Edge Distance
It is very important not to install the anchor any closer than 3" from an unsupported edge of the concrete.
