Each anchor consists of an unthreaded pin set into a metal sleeve. Simply drill a hole into the concrete, hold the fixture you’re fastening over the hole, then use a hammer to tap the anchor into the hole. As you drive in the pin, the sleeve expands outward, trapping the anchor in the hole.

How long do concrete anchors need to be?

As a rule of thumb, the space for the nut and washer is equal to the diameter of the wedge anchor being used. For example, if a 2×4 is being fastened to concrete with a 1/2” wedge anchor then the minimum length of wedge anchor would be 1-1/2”(2×4) + 2-1/4”(minimum embedment) + 1/2”(space for nut and washer) = 4-1/4”.

How do I choose concrete anchors?

The best holding values are achieved when the concrete is hard and the embedment into the concrete is deep. The larger the diameter- the higher holding values the anchor will have. For example, a 3/4″ diameter anchor has a minimum embedment of 3-1/4″ and a 1/4″ anchor has a minimum embedment of 1″.
