The anchor is made from Grade 10B21 SAEJ403, ASTM B633, and is Zinc Plated. This anchor is designed for use in Concrete & Grout Filled CMU

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 5/8" hole to be drilled in the base material (Concrete & Grout Filled CMU). The hole should be drilled with carbide tipped bit that meets ANSI standards and used in a hammer drill.

Driver Required
A 15/16" is required for driving the anchor into the base material.

Diameter of Anchor
The diameter of the anchor is 5/8".

Length Anchor
The length of the anchor is 8"

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 5/8" diameter anchor requires the hole in the fixture to be 13/16".

Wrench Size
The size of the wrench required to turn the nut to set the anchor is 15/16".

Spacing between Anchors
Each anchor must be spaced a minimum distance of 3" from each other when measured center to center.

Edge Distance
It is very important not to install the anchor any closer than 1-3/4" from an unsupported edge of the concrete.

The anchor is stamped with the letter 8 on the threaded end to allow inspection of the anchor after installation. The letter "8" designates an overall length of the anchor as between 8" up to, but not including 8-1/2" in length.

Installing a 5/8" x 8" Simpson Strong-Tie Titen HD Screw Anchor Zinc Plated (ea) THDB62800H
  1. Drill a 5/8" 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" is met.
  3. Clean the hole with a wire brush, vacuum, compressed air, or a blow-out bulb.
  4. Insert the point of the 5/8" x 8" Simpson Strong-Tie Titen HD Screw Anchor Zinc Plated (ea) THDB62800H into the hole. Make sure that the screw being installed will penetrate the base material a minimum of 1" but no deeper than 1-3/4".

  6. Always use proper personal protective equipment per manufacturer's and OSHA instructions.
