The split drive anchor is a one-piece pre-expanded expansion anchor made of carbon steel. It’s designed for use in a solid base material like concrete. It’s best used in in dry, interior, non-corrosive environments.
The anchor is hammered into a 1/4” hole. The two pre-expanded halves are compressed on the way into the hole. Once in the hole, the two halves attempt to regain their original shape and hold the anchor in place by friction.
This anchor is suited for permanent, tamper-proof installation. It is best for light duty fastening into concrete.
Yes, this anchor is used to permanently fasten. The only ways to remove the fastened object are cutting off the head off of the anchor, destroying the object being fastened, or pulling the anchor out to concrete failure.
These anchors are made of Grade 2 carbon steel with a zinc coating.
The split drive anchor is only available in a 1/4” diameter.
To determine which length is needed, add the minimum embedment of 1-1/8” to the thickness of the material being fastened. Round head split anchors are measured from underneath the head while flat countersunk head anchors are measured as an overall length including the head.
The round head anchor has a rounded top with a flat bottom. Its length is measured from underneath the head. The flat head anchor has a beveled bottom used to countersink the anchor into the wood being fastened. The flat-headed anchor is measured as an overall length including the head.
This anchor is designed for use in solid concrete. It should not be used in hollow base material, such as brick or block.
It is easy to install. Prepare the hole, drill the hole, clean the hole, and install the anchor. For detailed instructions, please visit our Tips & Tricks.
Yes. A hammer drill will create a hole that meets the tolerance requirements of the anchor
No. This anchor can be driven into the concrete with a standard hammer.
The minimum embedment is 1-1/8”.
Yes, it is important. Cleaning the hole ensures proper holding values for installation of the anchor.
They all have the same values because they all have been tested at the same embedment depth of 1-1/8”.
These anchors should be spaced a minimum of ten anchor diameters from each other, measuring from center to center.
The major difference is that the split drive anchor has two pre-expanded halves while the spike has an “S” curve in the body of the anchor. The spike is sold only through Powers Fasteners and the split drive anchor is sold by many different manufacturers.
There is no “best” anchor because each anchor has unique features and benefits. In most instances, determining which fastener is the best for a project is based on the specific application and personal preference.
No. The zinc-plated anchor should not be used in ACQ treated lumber.
No. The flat head anchor has a beveled head that would not sit flush against a washer. If a washer is required, then the use of a round-headed anchor should be considered.
No. The anchor is only available in Grade 2 carbon steel with a zinc coating.
No, it is imported.
