How do I stop my Tapcons from breaking?
The correct setting for driving a tapcon concrete screw without breaking or shearing off is determined by using the lightest setting and then moving up until the tapcon concrete screw is set tight against the fixture being fastened. It is very important that the tapcon is not over torqued.
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.
Do Tapcon screws need pilot holes?
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 carbide bit diameter required for the 3/16” screw is 5/32”.
How long should concrete cure before using Tapcon screws?
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.)
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.
Why do my screws keep breaking?
Without a pilot hole, the screw is essentially wedging itself into the wood. This puts a lot more pressure on the screw as well as the wood. In weak woods, this can cause a split; with weak screws, the screw can break. Drill using a wood bit of a diameter slightly smaller than the screw.
How much weight will a Tapcon screw hold?
*A safety factor of 4:1 or 25% of ultimate pullout/shear value is generally accepted as a safe working load. 340 lbs.
How much weight will a Tapcon hold?
How soon can you drill fresh concrete?
You can drill the hole after 24 hours, but it would be better to wait an extra day. In addition, the insert you use to hold anything down will readily break free if you tighten it down, even after 2 days. It would be better to wait a week before any kind of real torquing down of any kind of fasteners.
How long should concrete cure before putting weight on it?
Curing time of concrete is typically 24-48 hours, at which point it’s safe for normal foot traffic. After one week, concrete is typically cured enough to handle continued construction including heavy machinery.
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.
Why does my Tapcon screw keep breaking in half?
If the material is too abrasive and the lead thread is worn down during installation, the Tapcon® screw will stop tapping threads. This continued torquing of the screw can shear the Tapcon® in half. Find another concrete fastener to use such as a hammer drive or split drive concrete anchor .
What happens if I over torque the Tapcon?
Do not over torque the Tapcon, as this may cause it to spin in the hole, which causes the holding value to be lost. Turning the screw by hand the last couple of revolutions can help to prevent this situation.
Why won’t my Tapcon go in?
When you try to drive the tapcon in, the dust would prevent it from going the depth it needs to go. Try getting as much dust out as possible or drill the hole deeper so the dust is below the depth of the length of the tapcon.
What is Tapcon®?
Tapcon® is the brand name for the original concrete screw and is manufactured in the United States. Many companies sell concrete screws but they are not Tapcons. In most cases, these screws are simply imported than painted blue to look like Tapcons.
