For example, a 2×4 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”.
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.
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.

How deep should Tapcons be in 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.
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.
Can you put pressure treated wood directly on concrete?
YES. Any exterior concrete that is in contact with earth may wick moisture. Thus, it is required to place pressure treated wood directly against the concrete if one wishes next to build off that concrete with untreated wood.
How much weight can a 1/2 Tapcon hold?
1,360 lbs. *A safety factor of 4:1 or 25% of ultimate pullout/shear value is generally accepted as a safe working load. 340 lbs.
Can Tapcons be used in cinder block?
Insert the anchor into the pre-drilled pilot hole in the cinder block and expand as needed. Concrete screws and tapcon need a hole to be drilled in the masonry that is smaller than the designated diameter. All masonry screws’ packaging will show the best size of drilled hole to use.
What size is a Tapcon head?
Length of Hex Head Tapcon Screws Hex head tapcon comes in seven lengths in the 3/16” diameter: 1-1/4”, 1-3/4”, 2-1/4”, 2-3/4”, 3-1/4”, 3-3/4” and 4”. They are available in nine lengths in the 1/4” diameter: 1-1/4”, 1-3/4”, 2-1/4”, 2-3/4”, 3-1/4”, 3-3/4” and 4”, 5”, 6”.
How do you bond wood to concrete?
One of the best ways to secure wood to concrete is also the easiest: epoxy glue. There are certain epoxies that are manufactured specifically for wood-to-concrete use, and you can try using one on its own or combined with nails or screws.
Why can’t I drill through concrete?
Drilling into concrete is difficult because concrete is dense, is hard, and has embedded aggregate stones that can be obstacles to the drill bit. Drilling can quickly dull drill bits. When the bit encounters aggregate, the bit drags even more.
What size hole do you drill for a 1/4 Tapcon?
The Tapcon drill bit that is used depends on the diameter of the Tapcon screw being installed. The 3/16” Tapcon requires the use of 5/32” diameter bit, and the 1/4” Tapcon requires a 3/16” diameter bit.
What size hole do I drill for a 3/8 concrete anchor?
Drill hole into the concrete using a carbide tipped bit. Bit size = 3/8” (same as anchor diameter) Drill the hole at least 1/2″ deeper than the length of the anchor. 2. Clean out the hole using a wire brush, compressed air, vacuum, blow out bulb or other method.
Are Tapcons strong?
Stainless Steel Tapcons are reliable, strong, and have outstanding corrosion resistance. These screws are ideal for using to attach fixtures and lumbers to all types of masonry bases, including concrete, brick, and block.
How far apart should Tapcon screws be placed?
First, the minimum recommended distance between any two anchors is 10x the anchor diameter (2 1/2 inches for 1/4 inch anchors), at the risk of weakening the holding strength of each.
Why do Tapcons break?
The depth of the hole for a Tapcon® should be a minimum of 1/2″ deeper into the base material than the screw will penetrate. If the Tapcon® screw bottoms out in the hole before it is fully inserted and too much torque is applied, the Tapcon® may break or shear off.
Can you use a regular drill for Tapcon?
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®.
What sizes do Tapcon screws come in?
The stainless steel Tapcon comes in a 3/16” diameter in the flat countersunk head and in a 1/4” diameter with the hex washer head and the flat Phillips countersunk. Length – Both the 3/16” and the 1/4” Tapcon are available in the same lengths, with the 1/4” also available in lengths of 5” and 6”.
Are Tapcons self tapping?
Self-tapping screws are concrete screws that tap threads into the base material such as concrete, brick or block. The original self-tapping and the most widely recognized one is called Tapcon, which is derived from Tapping Concrete.
