CONFAST HDS31678 – Frequently Asked Questions
1) What sizes do CONFAST HDS stainless hammer drive anchors come in?
CONFAST HDS hammer drive anchors are offered in 3/16" x 7/8", and in 1/4" diameter at 1", 1-1/4", 1-1/2", 2", 2-1/2", and 3" lengths. Pick the length so the anchor embeds properly in the concrete after passing through whatever you are fastening down, since the fixture thickness eats into the usable length.
2) What substrates will a hammer drive anchor hold in?
Concrete, block, and masonry. The CONFAST HDS is set by driving the pin into a pre-drilled hole in solid base material. It is not a hollow-wall anchor, so drywall, stud cavities, and hollow block webs are the wrong application - use a toggle or sleeve-type anchor there.
3) Do I need a special setting tool to install these anchors?
No. The hammer drive design sets with a standard hammer once the hole is drilled, no setting tool or torque wrench required. You do need a hammer drill and a carbide bit matched to the anchor diameter to make the hole.
4) Are hammer drive anchors removable, or is this a permanent fastener?
Treat it as permanent. A drive pin anchor is set by expanding the body against the hole wall and is not designed to back out and reuse like a sleeve or wedge anchor with a nut. If you need the fixture to come off again later, a female-threaded drop-in or a machine screw anchor is the better choice.
5) How many anchors come in a box of CONFAST HDS?
Each box holds 100 anchors, which is how the HDS is packaged across the size range. For crews laying out conduit straps, strut, or furring on a large pour, that lets you count material by the box instead of by the piece.
