Diameters. 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 drill bit do I need for a 3/16 concrete screw?
The 3/16” diameter masonry screw requires the use of 5/32” carbide tipped bit for drilling the hole. The 1/4” diameter requires the use of a 3/16” carbide tipped bit.
Do I need to pre drill for Tapcon screws?
Before a Tapcon masonry screw can be installed, a hole must be drilled into the masonry. Use a hammer drill to ensure that the hole has the proper tolerance. The hammer motion breaks up the masonry material and the rotation removes the dust from the hole.
How much weight can a 3/16 Tapcon screw hold?
Technical Specifications for Tapcon Concrete Screws Size Minimum Embedment Shear (lbs.) 3/16” 1” 720 1/4” 1” 900.
How much weight can a 3/16 masonry screw hold?
3/16″ 1/4″ 720 lbs. 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 drill bit do I use for a 3/16 Tapcon?
The 3/16” Tapcon requires the use of 5/32” diameter bit, and the 1/4” Tapcon requires a 3/16” diameter bit.
How big is a 3/16 drill bit?
Drill Bit Hole Diameters Metric Size Fractional Size 1 mm .0394 5/32 2 mm .0787 11/64 3 mm .1181 3/16.
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.
Do I need a hammer 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®.
Can you install Tapcons without a hammer drill?
A Tapcon screw is installed with a regular twist drill or impact drill. The HOLE that the Tapcon goes into is usually drilled with a hammer drill. Although if the material is somewhat soft, like a cinder block, a regular twist drill and a good bit will work, too.
What size 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.
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.
What grade are Tapcon screws?
The stainless steel Tapcon® is manufactured from a 410 stainless steel that is coated with silver Climaseal®. The standard large diameter Tapcon® or LDT has an anchor body made from Grade 5 hardened carbon steel that is zinc plated.
How long of a Tapcon screw do I need?
The proper length could be either the 2-3/4″ or the 3-1/4″ length concrete screw. The 3-1/4″ screw would be right at maximum embedment and depending on the abrasiveness of the base material, may be too long.
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.
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 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”.

Why do my Tapcons keep breaking?
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.
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.
Who owns Tapcon?
RED HEAD® > Products > Screw Anchors > Tapcon.
How far apart should Tapcon screws be placed?
Rule: Concrete fasteners should not be set closer than 10-anchor diameters from each other.
Which drill bit is for concrete?
Drill bits that can drill through concrete are called masonry bits. They are also good for drilling through brick and stone. Drill bits with a tungsten carbide tip are the strongest; when it comes to solid concrete, the sharper the better. Masonry bits cut holes through concrete in two steps.
How long should concrete cure Tapcon?
A full cure takes 28 days if you go by how long they prevented us from driving over a new road surface on a small local bridge. I don’t know how that relates to driving Tapcons. 10-13-2017, 10:37 AM (This post was last modified: 10-13-2017, 12:23 PM by brianwelch.)Oct 13, 2017.
