Installation Video
Installing a 3/4" x 8-1/2" Hot-Dipped Galvanized Thunderstud Wedge Anchor
  1. Drill a 3/4" 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 3-1/4" is met.
  3. The hole can be drilled while the fixture is in place. The minimum hole in the fixture for the 3/4" x 8-1/2" Hot-Dipped Galvanized Thunderstud Wedge Anchor is 1".
  4. Clean the hole with a wire brush, vacuum, compressed air, or a blow-out bulb.
  5. Put the nut and washer on the 3/4" x 8-1/2" Hot-Dipped Galvanized Thunderstud Wedge Anchor, making sure the nut is on the last threads; this will protect the threads from damage when the wedge anchor is hammered into the hole and into the concrete.
  6. Insert the anchor through the hole in the fixture and into the hole in the base material.
  7. This should be a very tight fit. Then use a hammer to complete the installation until the nut and washer are tight against the fixture. It is important that the threads go below the surface of either the base material or the fixture.
  8. Turn the nut clockwise on the anchor until finger tight.
  9. Using a 1-1/8" wrench, turn the nut 3 to 4 times until snug or until the proper torque value of 150 - 175 ft./lbs. is reached.
  10. Always use proper personal protective equipment per manufacturer's and OSHA instructions.
