CONCRETE FASTENERS AVAILABLE INCLUDE:
Wedge Anchors – for use in solid concrete, available in zinc-plated carbon steel, hot-dipped galvanized, 304 stainless steel and 316 stainless steel. The diameters range from 1/4” to 1-1/4” and lengths from 1-3/4” to 12”. To install a wedge anchor, a hole needs to be drilled into the concrete. The hole size in the concrete is equal to the diameter of the wedge anchor being installed. The hole must be drilled using a hammer drill and a carbide tipped drill bit. All wedge anchors have a minimum embedment depth that they must be installed in order to ensure minimum holding values. The minimum embedment depth is base on the diameter of the wedge anchor being used. Wedge anchors are packaged with the correct number and size of nuts and washer; package quantities depend on the diameter and length of the wedge anchor.
Sleeve Anchors – used in solid concrete, brick and block, available in zinc plated carbon steel and 304 stainless steel. The diameters range from 1/4” to 3/4” and in lengths from 5/8” to 6-1/4”. The hole must be drilled into the base material with a hammer drill and a carbide bit, with the hole size equal to the diameter of sleeve anchor being installed. All sleeve anchors come packaged fully assembled with a nut and washer. Sleeve anchors in the 1/4” diameter come with an acorn nut, flat-head or round head. The 3/8” diameters sleeve anchor come in a hex nut head or a flat head countersunk Phillips. The 1/2”, 5/8” and 3/4” come in only the hex nut head. Each diameter of sleeve anchor must be installed into the base material a minimum distance. This minimum embedment must be achieved for the sleeve anchor to provide minimum holding values in the base material. Zinc plated sleeve anchors are for dry indoor applications and the 304 stainless steel sleeve anchors are designed for outdoor wet applications.
Tapcon – used in most masonry base materials such as concrete, brick, and block, and is available in the standard blue Climaseal® coating and 410 stainless steel. Diameters range from 3/16” to 3/4” and lengths from 1-1/4” to 6” with two standard head styles of the hex washer head and the flat Phillips countersunk. Both the 3/16” and 1/4” diameter tapcon must be installed into the concrete a minimum of 1” and a maximum of 1-3/4”. To determine the length of tapcon to use for any particular application, add the thickness of the material being fastened to the minimum embedment depth of 1”. The maximum length of tapcon to use is determined by adding the thickness of the material being fastened to the maximum embedment depth of 1-3/4”. The length of the hex head tapcon is measured from underneath the head, the flat head phillips tapcon is measured as an overall length including the head.
Drop-In Anchors – female type anchor designed for use in solid concrete only comes in only 5 diameters of 1/4”, 3/8”, 1/2”, 5/8” and 3/4” and each diameter comes in only one length. Each diameter is available in zinc plated carbon steel, 304 stainless steel, and 316 stainless steel. The drop-in anchor requires the use of a setting tool to set the drop-in anchor in the concrete. Each diameter of the drop-in anchor has a setting tool specifically for that diameter.
Hammer Drive Anchors – used in concrete, brick or block with one length available in the 3/16’ diameter and seven different lengths in the 1/4” diameter. All of the hammer drive anchors come with a mushroom head and are set in the base material by driving the preassembled nail down into the anchor body.

Split Drive Anchors – manufactured in only zinc plated carbon steel and designed for use in solid concrete only. Two head styles are available: the flat head and round head in one diameter of 1/4”, with different lengths from 1-1/2” to 4” in the flat head and from 1-1/4” to 2-1/2” in the round head.
Nylon- Nail-It – available with a standard zinc plated carbon steel nail, aluminum nail or a nylon nail. Three head style are available: flat, round and mushroom head in diameters of 3/16” and 1/4” and lengths ranging from 3/4” to 3”.
Spike - similar to the split drive anchor and can be used in concrete, brick or block in static or vibratory loading applications. Five head styles are available the round, flat, threaded pipe, wire tie and forming double head style. The spike is available in an acorn plated carbon steel as well as in stainless steel.
