These figures indicate average ultimate tension and shear failure values. A safety factor of 4:1 or 25% of ultimate value is generally accepted as a safe working load. Reference should always be made to applicable codes. All values are based on close tolerance holes drilled with Buildex Tapcon® carbide drill bits. Performance of the Tapcon® anchor may vary in extremely hard concrete aggregates. Holding values will depend on the quality of the base material.

Tapcon Video Installation Instructions

Tapcon Installation Instructions
  • Tapcon® screws are one of the most popular concrete anchors on the market. Tapcons are designed for use in concrete, brick or block. The strength of these screws makes them versatile for use in many different applications. They require a slightly smaller hole than the diameter of the screw.
  • These concrete screws are available in a 3/16" diameter and a 1/4" diameter. The 3/16" diameter screw needs a 5/32" hole and the 1/4" diameter screw needs a 3/16" hole. To determine the length of the tapcon screw needed, add the thickness of the material to be fastened to a minimum of 1" and a maximum of 1-3/4". This will give you the proper length of screw needed.
  • When fastening to concrete, brick or block, a hole needs to be drilled into the base material. A hammer drill must be used because it will create the best quality hole. Once the bit is chucked into the hammer drill, the depth of the hole to be drilled can easily be set by using the depth gauge on the hammer drill or by simply wrapping the bit with tape at the depth that is required.
  • Use eye and ear protection when drilling into concrete, brick or block with a hammer drill. Also make sure that the hammer drill is in hammer mode. Begin drilling only after these safety concerns have been addressed. Continue drilling until the tape on the bit or drill gauge meets the base material. The hole must be cleaned of all concrete dust to ensure proper fastening. Using a wire brush and a vacuum or compressed air will ensure that the hole is cleaned properly. Place the fixture over the hole, making sure that the hole in the fixture is large enough to allow the Tapcon® screw to be inserted through it. Place the concrete screw through the fixture and into the hole. Use the drill or a wrench to turn the screw, allowing it to tap threads into the base material. It is important that the screw is not turned too fast, which will cause the base material to be stripped and the screw to just spin in the hole.



 

As 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.
