Easy to install and strong.
Really nice product. Worked great anchoring in posts for a gazebo. So fast to install and strong holding power. If you need to mount something to concrete and need extreme holding power, these are a great single piece option.

These are well built and I can use them in the holes where the smaller ones have worn out the hole.

Wrong size?
The 3/8” bolts were too small for the 3/8” hole I drilled. When I bought other 3/8” bolts they fit perfect. Even though the box said 3/8” I wonder if they were the wrong size in the box?
