What size Tapcon do I need for 2x4?

For example, a 2x4 is 1-1/2” thick, so the minimum length of tap con to use would be 1-1/2” + 1” = 2-1/2”. The maximum embedment for all tap con screws is 1-3/4”. Using the 2x4 example mentioned earlier, the maximum length tap con is determined by adding the thickness of the 2x4 of 1-1/2” + 1-3/4” = 3-1/4”.

What size Tapcons 2x4 bottom plate?

The 2x4 is 1-1/2" thick. Adding the 1-1/2" of the 2x4 plus a minimum of 1" embedment= 2-1/2". This would be the minimum length of screw that can be used. The maximum length would be 1-1/2" + 1-3/4"= 3-1/4", the maximum length of screw that can be used.

What diameter Tapcon should I use?

The Tapcon® screw requires the correct diameter of hole to be drilled for the diameter of the Tapcon® screw being installed. The 1/4” requires a 3/16” hole, and the 3/16” requires a 5/32” hole to be drilled into the base material.

What size Tapcon screw do I need?

Hole Diameter – the diameter of the hole to be drilled in the base material for the Tapcon is slightly smaller than the diameter of Tapcon being installed. A 3/16” Tapcon requires a 5/32” hole and a 1/4” Tapcon requires a 3/16” hole.

What size anchors for 2x4 concrete?

As a rule of thumb, the space for the nut and washer is equal to the diameter of the wedge anchor being used. For example, if a 2x4 is being fastened to concrete with a 1/2” wedge anchor then the minimum length of wedge anchor would be 1-1/2”(2x4) + 2-1/4”(minimum embedment) + 1/2”(space for nut and washer) = 4-1/4”.

What size screws 2x4?

If you are looking to join 2x4s, the best screw size to use in most cases is 2.5 inches long, gauge 8 or 9.

How deep should Tapcon screws go into concrete?

The minimum depth of embedment for the Tapcon screw is 1 inch, and the maximum embedment is 1-3/4 inch. The depth of the hole should be drilled to allow a minimum space at the bottom of the hole of 1/2 inch. The minimum depth of the hole equals 1 inch plus 1/2 inch or 1-1/2” inches.

Do you need a hammer drill for Tapcon screws?

The hole must be drilled using a hammer drill with a carbide tipped bit meeting ANSI standards. A bit that meets ANSI standards will ensure that the hole diameter will meet the requirements of the Tapcon®.

Are Tapcon screws better than anchors?

Tapcon and wedge anchors are pre-installed mechanical anchors that attach structural objects to concrete structures. However, the wedge anchor suits heavier-duty applications, vs the Tapcon anchor that typically serve lighter deployments. Another difference between them is in their fastening method.

What size screws basement framing?

The most common screw for joining two-by-fours is hardened steel, structural, No. 9, 2 1/2 inches long with a Phillips head. Other screw types appropriate for studs are specialized and may be harder to find and more expensive.

How do you choose concrete anchors?

The best holding values are achieved when the concrete is hard and the embedment into the concrete is deep. The larger the diameter- the higher holding values the anchor will have. For example, a 3/4" diameter anchor has a minimum embedment of 3-1/4" and a 1/4" anchor has a minimum embedment of 1".

What should I put between wood and concrete?

Anyplace where wood meets the ground or concrete, the lumber must be pressure treated. For additional moisture protection, a gasket or strip of closed-cell foam can be installed between the concrete foundation and the sill plate.
