Installing a 1/4" x 2-1/2" Split Drive Flat Zinc Plated- Drill a 1/4" hole into the concrete using a carbide-tipped bit that meets ANSI Standards B212.15.
- Drill the hole a 1/2" deeper than the anchor will penetrate the concrete, making sure the minimum embedment requirements of 1-1/8" is met.
- The hole can be drilled while the fixture is in place. The minimum hole in the fixture for the 1/4" x 2-1/2" Split Drive Flat Zinc Plated is 3/8".
- Clean the hole with a wire brush, vacuum, compressed air, or a blow-out bulb.
- Insert the 1/4" x 2-1/2" Split Drive Flat Zinc Plated through the material to be fastened and into the hole, ensuring that the bottom of the head is sitting flush with the fixture plate.
- Hammer the anchor until the head of the anchor is tight against the item being fastened.
- Always use proper personal protective equipment per manufacturer's and OSHA instructions.
