From the best I’ve found, the recomendation is to go at least 1″ into the concrete, and for tapcons, people tend to recomend the 1/4 vs 3/16″.
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 size Tapcons do I need?
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.
How much weight can a 1/4 Tapcon hold?
Technical Specifications for Tapcon Concrete Screws Size Minimum Embedment Shear (lbs.) 3/16” 1” 400 1/4” 1” 620.
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.
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.
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.
What size concrete screws do I need?
The 3/16-in. diameter screws are plenty strong for most home tasks like installing furring strips, screwing down walls to concrete floors, and attaching hardware to block or brick. And since they’re a little cheaper and the smaller hole is easier to drill, the 3/16-in. size is usually the better choice.
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.
How do you attach a bottom plate to a subfloor?
Push the outside edge of the bottom plate to the red chalk line where it will sit when raised. Tack the bottom plate to the subfloor using 8d or 16d nails approx. every 4′ (every other stud bay). – These should be toenailed on the inside of the wall, not on the outside (under the plate).
How far should anchor bolts be spaced?
Bolts shall be embedded at least 7 inches (178 mm) into concrete or masonry, and spaced not more than 6 feet (1829 mm) apart.
Do bottom plates need to be pressure treated?
Both wood and concrete wick water well because they are porous materials. Pressure-treated bottom plates deal with the symptoms of the problem when a capillary break between wood and concrete deals with the cause. No direct contact, no need for pressure-treated bottom plates.
What should I put between 2×4 and concrete?
Spray insulating foam into crevices between the sill plate and the concrete slab as an alternative to caulk. Choose a foam product that has waterproofing properties as well as insulating properties.
How do you anchor a sill plate to concrete?
How to Attach Sill Plates to Concrete Position the sill plate in place on the concrete slab or foundation. Drill holes through both the sill plate and into the concrete, using a concrete masonry drill-bit. Insert one wedge anchor bolt set into each drilled hole and hammer it into place with a hammer.
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 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.
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®.
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.
Are Tapcon screws any good?
They are also a very unique (and of course proprietary) product that allows for extremely fast and reliable anchoring of materials to masonry products. If you drill the hole correctly – deep enough and with the correct diameter bit – these fasteners will simply work every time.
