Red Head LDT-1260 Large Diameter Tapcon 1/2-Inch by 6-Inch Anchor (20 per Box)

These provide incredible holding power and survived installation with an impact wrench. They were used to hold 4x4s to a floor as the base course of an 7” high retaining wall. Solid anchors with zero movement.

They worked great. I installed them through porcelain tile laid on top of a concrete slab.

Better value than Home Depot or Lowes. I used these in asphalt to replace 4"x1/2" Tapcon anchors that were too short & not strong enough to hold fence post in asphalt. My fault, but the choice was limited at the stores & I didn't know at the time. I used these for 1 1/2"x6' fence post which work well. I used 8"x5/8" anchors for 2 1/2" gate supporting fence post. The quality & price was right,

I ordered three boxes of these bolts in August for a house I am building with my wife. When I opened the third box this week, the bolts were in fact four inches long, not six as the label on the box indicated. It appears to me that the wrong label was put on the box in the factory...Regardless, when I contacted the seller (three months after purchase) they immediately offered a replacement box at no charge. How can one reasonably expect better customer service?

Great price. Holds things to concrete like a boss. Suggestion level: buy here not Lowe's

Just what I needed to secure posts for a Gazebo that I'm building. Very solid.
