The 3/16” diameter hammer set comes in only one length of 3/4”. Hammer drives come in two diameters of 3/16” and 1/4”. The head is configured so that the nail, once set, is even with the top surface of the head of the anchor. The hammer drive anchors are not removable once set. The anchor body is relatively soft and pliable, allowing the anchor body to conform to the uneven surface of the hole in the brick. The hammer drive anchor comes with mushroom head, which is a low profile head that is about 1/2” across to provide an excellent bearing surface against the material being fastened. Hammer Drive Anchor– is similar to the nylon nail-it because it works with the same principles. The body of the anchor is made from zinc aluminum magnesium and copper alloy with a steel or stainless steel nail.Keep in mind that the nylon nail-it is a very light duty type anchor and should only be used in applications where the fixture being fastened does not weigh much. The nylon nail-it with the nylon nail or aluminum nail is excellent for use in applications where rust resistance is critical.
Some sizes are available with a nylon nail or an aluminum nail. Not all head styles come in both diameters or in all lengths. I t is available in two diameters of 3/16” and 1/4” and lengths from 3/4” to 3”. Nylon nail-its come in three head styles of mushroom head, flat head, and round head. They are set into the brick by driving the nail with a hammer into the anchor body, and the anchor body expands against the walls of the hole in the brick. Nylon-Nail-its- are a light-duty type of brick anchor that has a nylon body with a steel nail.When installing the tapcon, a hammer drill must be used with a bit that has a carbide tip. The tapcon brand concrete screw comes in the standard blue Climaseal® coating or a 410 stainless steel coated with a silver Climaseal® coating. The hole that is drilled into the brick is slightly smaller in diameter than the diameter of tapcon being installed a 3/16” tapcon requires a 5/32” hole and the 1/4” tapcon requires a 3/16” hole. When this happens, the tapcon stops tapping and, if continued torque is applied, the tapcon may shear off. The only problem that may occur when using tapcon in brick is when the very hard abrasive brick is used, the lead threads’ ability to tap the brick may be diminished before the head of the tapcon is tight against the fixture being fastened. 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.
