How to Fasten a Sign to Concrete Using Tapcons

Tapcon® screws can be used when you need to fasten/attach a sign to concrete. Tapcons are designed for use in concrete and are manufactured with a hex washer head that is perfect for attaching signs to concrete. The size of the hole that needs to be drilled in the concrete depends on the diameter of the concrete screw being used. A 3/16" diameter Tapcon® requires a 5/32" bit and a 1/4" diameter Tapcon® requires a 3/16" bit. Tapcons have special hardened threads that tap into the concrete. These concrete screws should be embedded into the base material a minimum of 1" and a maximum of 1-3/4". The minimum length of the screw chosen should be determined by adding the thickness of the material being fastened to the maximum embedment of 1". The longest screw that should be used is determined by adding the thickness of the material being fastened to the maximum embedment depth of 1-3/4".

A hammer drill must be used when fastening a sign to concrete, brick or block base material because it will provide the best quality hole tolerance. Hole tolerance is critical when installing fasteners into the base material. The hammer motion breaks up the material and the rotation pulls the material out of the hole. It is important to always wear eye and ear protection when using a hammer drill. The hole for a Tapcon® screw should always be drilled 1/2" deeper into the base material than the screw will penetrate the concrete. When using concrete screws in outdoor applications, stainless steel Tapcons should be used since they are more rust resistant and will provide an attractive appearance that will last for a longer period of time.

Below are step by step instructions on how to use Tapcons to fasten/attach a sign to concrete:

1. Once a location has been chosen for the sign, place the sign on the concrete and mark the hole locations on the base material.

2. Using a hammer drill, drill the correct diameter of the hole for the Tapcon® being used. A 3/16" diameter should have a 5/32" hole drilled while a 1/4" screw should have a 3/16" hole drilled. Make sure that the hole is drilled a minimum of 1/2" deeper than the screw will penetrate the concrete.

3. Clean the hole of all debris and dust created during the drilling process.

4. Place the sign back into position and insert the concrete screw(s) through the sign and into the hole drilled in the concrete.

5. With the drill in rotation mode, turn the screw slowly. Avoid stripping the threads being tapped into the concrete. Keep turning the screw slowly until the head of the screw is flush with the sign. Repeat this procedure for all holes drilled.

Tapcon® screws are an excellent choice for attaching a sign to concrete. It is important to follow all instructions when installing Tapcons to ensure proper and safe placement of these concrete anchors.

Always use personal protective equipmentAs with any anchoring project, it is important to keep safety in mind and follow instructions carefully. Always remember to wear safety goggles, handle all tools with extra care and follow all technical specifications. This article is meant to serve only as a basic explanation of concrete fasteners. Always refer to manufacturer's instructions or consult a contracting expert during any anchoring project.
