The threads of the tapcon tap the brick providing excellent holding values. Both diameters come in lengths of 1-1/4”, 1-3/4”, 2-1/4”, 2-3/4”, 3-1/4”, 3-3/4” and 4” the 1/4” diameter also comes in lengths of 5” and 6”. A hole must be drilled into the brick before inserting the tapcon screw. They come in a hex washer slotted head and a flat Phillips countersunk, and are available in 3/16” diameter and 1/4” diameter. Tapcons® – is the brand name and most wildly recognized name for the self-tapping screw for brick and it is manufactured in the United States.A hammer drill with a carbide tip must be used to drill the hole in the brick. The hole that is required to be drilled into the brick is the same diameter as the sleeve anchor being used. All sleeve anchors come pre-assembled and ready to use. Zinc plated sleeve anchors should be used in indoor dry areas, stainless steel sleeve anchors should be considered for use in outside applications. Sleeve anchors provide the widest variety of head styles and they come in round slotted head, flat Phillips countersunk, acorn head or the standard hex nut. Sleeve anchors are versatile and can be used in solid brick, brick with holes or the mortar joint. Sleeve Anchors- are male type anchors that are manufactured in diameters from 1/4” to 3/4” and are available in many lengths to accommodate different material thickness.Because hole size equals anchor size, a smaller hole is needed for the diameter of the male anchor being used as compared to the larger hole required for a female type anchor. A wide variety of head styles is available depending on the diameter and type of fasteners chosen. The fastener to be inserted through the fixture can be fastened directly into the hole drilled into the brick. Male anchors allow the hole to be drilled with the fixture in place.The female type anchor will give a more finished look because the head style and type of bolt used will not protrude a far distance from the surface. Female type anchors also require a large hole to be drilled because the hole size is equal to the outside diameter of the anchor. When there is more than one anchor, it may be difficult to get all the holes lined up properly for installation.
Female anchors would require the spotting of the anchor and then place the fixture over the holes.
