The DEWALT 02826-PWR Zamac Nailin is a light-duty hammer-drive anchor with a corrosion-resistant Zamac alloy body and carbon steel drive pin. The mushroom-head anchor installs quickly by drilling the required hole, inserting the anchor through the fixture and driving the pin until the head is seated. It is suitable for general-purpose and tamper-resistant fastening into normal-weight concrete, hollow concrete masonry, brick masonry and stone. The 1/4-inch diameter anchor is 2 inches long, uses a 1/4-inch drill bit and is packaged 100 anchors per box. This anchor is not recommended for overhead, life-safety or sustained tensile-load applications unless the application has been specifically evaluated.
