Installing a 1/4" Drop-In Anchor Zinc Plated
  1. Drill a 3/8" hole into the concrete using a carbide-tipped bit that meets ANSI Standards B212.15.
  2. The depth of the hole can be deeper or equal to the minimum embedment depth of 1" which is equal to the length of the anchor .
  3. Clean the hole with a wire brush, vacuum, compressed air, or a blow-out bulb.
  4. Insert the anchor into the hole with the open threaded end facing up.
  5. Take the correct 1/4" Drop-In Anchor Zinc Plated setting tool and insert the smaller diameter end into the threaded portion of the 1/4" Drop-In Anchor Zinc Plated.
  6. Strike the end of the setting tool with a hammer until the anchor is fully set.
  7. The 1/4" Drop-In Anchor Zinc Plated is now set. A 1/4" diameter threaded rod or a bolt can be inserted into it with a maximum torque of 5 ft. lbs.
  8. Always use proper personal protective equipment per manufacturer's and OSHA instructions.

* The bits are recommended by diameter and may not necessarily be the length needed for your application. Please make sure the usable length will work for your application. *
