Installing a CONFAST® Concrete Screw? Follow these steps for a secure and reliable installation:
1. Drill the Hole
Drill a 5/32" hole into the concrete using a carbide-tipped bit that meets ANSI Standards B212.15.
2. Drill to the Proper Depth
Drill the hole 1/2" deeper than the anchor will pe*****te the concrete, ensuring the minimum embedment of 1" is met.
3. Drill Through the Fixture (If Needed)
The hole can be drilled while the fixture is in place. The minimum fixture hole size for the 3/16" x 1-1/4" Hex Head CONFAST® Concrete Screw is 1/4".
4. Clean the Hole
Remove dust and debris using a wire brush, vacuum, compressed air, or blow-out bulb.
5. Insert the Screw
Insert the point of the screw into the hole. Make sure it pe*****tes the base material at least 1" but no deeper than 1-3/4".
6. Drive the Anchor
Using a 1/4" nut driver hex driver, turn the screw clockwise, applying slight pressure until the head is snug against the material being fastened.
Safety Reminder
Always use proper personal protective equipment (PPE) according to manufacturer and OSHA guidelines.
