What size Tapcon 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 will a Tapcon hold?
*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 drill bit do you use for a 1/4 tap?

Drill the hole a 1/2″ deeper than the anchor will penetrate the concrete, making sure the minimum embedment requirements of 2-1/4″ is met. The hole can be drilled while the fixture is in place. The minimum hole in the fixture for the 1/2″ x 5-1/2″ Wedge Anchor Zinc Plated is 5/8″.
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.
Why are my Tapcons not working?
When A Tapcon Won’t Go All The Way In Typically what happens is that as you drive the Tapcon in some of the residual concrete dust is left in the whole from drilling. This dust compacts at the bottom of the hole not allowing for the Tapcon to be driven in fully. Clean out the hole before driving the Tapcon in.
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.
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.
