How far apart should concrete screws be?
A rule-of-thumb in the concrete-fastener industry is that the minimum spacing should be 10 diameters from each anchor, and measured center to center. The spacing from an unsupported edge should be at least five-anchor diameters.
How far apart are Tapcons?
Rule: Tapcon® concrete screws have a minimum embedment of 1″ for both the 3/16″ and 1/4″ diameter and a maximum embedment of 1-3/4″. Explanation: Tapcons cut threads into the base material. The lead thread does all of the cutting and will become ineffective after reaching 1-3/4″ embedment.
How far should a Tapcon screw 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.
How many concrete anchors do I need for a wall?

How long does concrete need to cure before using Tapcon?

Why are Tapcon screws blue?
Tapcon’s unmatched performance in concrete, block and brick applications make them an excellent alternative to expansion anchors, plugs and lag shields. Blue corrosion resistant coating enables them to withstand the harshest conditions.
What size Tapcons 2×4 bottom plate?
The 2×4 is 1-1/2″ thick. Adding the 1-1/2″ of the 2×4 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.
How far apart should sill plate anchors be?
Bolts shall be embedded at least 7 inches (178 mm) into concrete or masonry, and spaced not more than 6 feet (1829 mm) apart.

How long Tapcon do I need?
The Tapcon® screw requires a minimum embedment of 1” and a maximum embedment of 1-3/4”. To determine the maximum length screw to use for any specific application, add the thickness of the material to the minimum embedment of 1” to get the minimum length screw required.
What diameter Tapcon should I use?
The 3/16” tapcon uses a 5/32” bit, the 1/4” tapcon needs a 3/16” diameter bit, the 3/8” tapcon requires a 5/16”, the 1/2” tapcon requires a 7/16” bit, a 5/8”tapcon needs a 1/2” bit and the 3/4” tapcon requires the use of a 5/8” carbide tipped bit.

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 2×4 is being fastened to concrete with a 1/2” wedge anchor then the minimum length of wedge anchor would be 1-1/2”(2×4) + 2-1/4”(minimum embedment) + 1/2”(space for nut and washer) = 4-1/4”.
