Applications 
The anchor is made from 316 Stainless Steel. This anchor is designed for use in Concrete only, and should never be used in block or brick base material.

Environment 
The anchor is designed for use in a submerged/chemicals environment.

Hole Diameter/Bit Diameter 
 
The anchor requires a 1/4" hole to be drilled in the base material (Concrete only). 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 3-1/4"

Thread Type  
The threads on the anchor are national coarse threads that measures 1/4" with 20 threads per inch, commonly referred to as 1/4"-20.

Thread Length 
The length of the threads on the anchor is 2-7/16" in length.

Packaging 
The anchor is packaged with 100 pieces per box and is packaged with the correct number and diameter of nuts and washers.

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.

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 4 ft./lbs.

Markings 
The anchor is stamped with the letter D on the threaded end to allow inspection of the anchor after installation. The letter "D" designates an overall length of the anchor as between 3" up to, but not including 3-1/2" in length.
