The bottom lip of the anchor is tapered. It is permissible for a section of the shield to be knurled, to increase the gripping action of the anchor. Intended for flush mounted, medium to heavy-duty applications in solid materials such as stone and concrete. It can be used in, but are not limited to, overhead assemblies such as duct work and pipe hangers because the internal plug holds its position. Can also be used to anchor handrails and floor-mounted door stops.

The outer surface of the shield is designed with ribs or corrugations to resist turning. The nut is either conical or eliptical in shape so as to fit within the shield body. Used in soft masonry with machine screws or machine bolts which are exposed to vibration or side pressure. The expander nut climbs the anchor bolt as it is tightened, expanding the shield body. The bolt can be removed and replaced without affecting the holding power of the anchor system. Can also be used in harder materials, including stone, brick or concrete. This anchor consists of four parts-- a two-piece tubular shield, a hollow, wedge-shaped cone and a wedge-shaped nut-- brought together into a single anchor unit. The shields are connected by a pair of spring bands. At one end is the nut and at the other the cone, each designed so as to not turn during expansion. Used in soft masonry with machine screws or machine bolts which are exposed to vibration or side pressure. As the anchor sets, the opposite ends pull towards each other causing the elongation of the anchor body. It doesn't fracture and allows for a fastening of any length. Can also be used in harder materials, including stone, brick, concrete or block. Expansion shield and nut may be made of alloy zinc, brass, malleable iron or steel. Anchors should be installed a minimum of ten anchor diameters between each other and a minimum of five anchor diameters from the edge. Should be equal to or slightly longer than the length of the anchor. Expansion anchors shall not be removable or show evidence of failure when subjected to axially applied proof test loads as specified in the above table when set in concrete of 3000 psi. compressive strength.the suggested safe working load is one-fourth the average proof test loads shown in the above table. 265

Specifications Wedge Anchor Anchors Ultimate Plating A four-piece assembly consisting of (1) an anchor bolt threaded at one end with a unified pitch, and a shoulder at the opposite end which retains a free-spinning clip, (2) a clip with three lateral slits and projections designed to exert greater holding power the greater the load that is applied, (3) a hex nut, and (4) a flat washer. These are heavy-duty, non-bottom bearing anchors of greater shear strength than other light and medium-duty expansion anchors. The design of the expansion clip assures full contact with the masonry. Wedge anchors withstand temperature fluctuations well. For best performance, minimum anchor spacing should be 10 hole diameters and minimum edge distance be 5 hole diameters.

The head height of the threshold flat head is less than a standard flat head sleeve anchor. The anchor works by expanding against the material in which it is embedded. When the flat head is turned clockwise the conical end is pulled into the dilating sleeve pushing it outward 360 around the anchor into the masonry. They are designed to be used in solid or hollow masonry, including cinder block, brick, marble and concrete. One advantage of the sleeve anchor is that it can be removed after it's been installed. Another is that the length of the sleeve induces less stress on the substrate than does a wedge anchor. The flat head variety is well-suited for anchoring windows and doorframes. The threshold flat head design is specifically for anchoring thresholds and is only available in steel.

The anchor works by expanding against the material in which it is embedded. When the hex nut is tightened the conical end is pulled into the dilating sleeve pushing it outward 360 around the anchor into the masonry. They are designed to be used in solid or hollow masonry, including cinder block, brick, marble and concrete. One advantage of the sleeve anchor is that it can be removed after it's been installed. Another is that the length of the sleeve induces less stress on the substrate than does a wedge anchor. It is well-suited for permanently anchoring heavy equipment to concrete.

The hole through the center of the body has ribs on the outside to hold the anchor in place during installation. When a tapping screw is driven into the toggle, the legs collapse which forms a tongue. As the screw is driven through the body, it pulls in and expands the legs. Plastic toggles are intended for lightweight duty in hollow walls (wallboard or plaster), ie. drapery rods, junction boxes, soap dishes, towel bars, etc.. The anchor remains in place even after the screw is removed. Engineered Plastic Anchors should be spaced 18-24 inches center to center (spacing can be closer in high-density material).

Some applications include anchoring the following to masonry: electrical junction boxes, wooden beams, plywood, exterior insulation, metal flashing, thresholds. Case hardened AISI 1022 steel Concrete screws should be installed a minimum of ten anchor diameters between each other. They have an advantage over most other types of masonry anchors in that they can be installed close to the edge of the material in which they are installed.

The shank has several ribs extending completely around its circumference. Mushroom, pan and flat head styles are available; (2) a steel pin expander which passes through a concentric channel extending from an opening in the top of the head of the nylon piece down into the shank to a point just below the spot where the split ends below the head. The pin has a slot across the top of its head, a chiseled point similar to a nail, and threads on its own shank which helps to lock the anchor in place upon installation. Installation is achieved by inserting the end of the nylon shank into a pre-drilled hole and hammering the head of the nail until it meets the head of the anchor body. Driving the nail through the body expands the split ends which allows the ribs to grip the wall of the prepared hole. This is a light duty anchor for use in solid materials such as concrete, brick and block, preferred when fixtures must be attached without chipping the fixture or the masonry. Can also be used like a toggle bolt in wallboard or plaster, or as a blind rivet in joining several thicknesses of material together, especially in applications subject to vibration. The nylon withstands temperatures from -40 F to 170 F. Body: Injection molded thermoplastic nylon Expander Pin: AISI 1018-1021 or equivalent cold rolled steel, zinc plated Anchors should be spaced 18-24 inches apart (measured from the center of the anchor) Hole should be drilled to a depth of at least 1/4" deeper than the required embedment. Likewise, the thickness of the base material should be at least 125% of the embedment to be used. Nylon nail anchors shall not be removable or show evidence of failure when subjected to axially applied proof test loads as specified in the above table when set in concrete of 3000 psi. compressive strength.

Toggle bolts are light-duty anchors for use in hollow block or gypsum wallboard. They spread the load over a larger area and are more temperature resistant than other hollow wall anchors. They are single-use anchors.

Used to anchor metal, plastic, wood, particle board or fiber board in concrete, block or brick. It doesn't require a pre-drilled hole and can be set with a hammer when using a setting tool designed for drive pins. Heat treated alloy steel Anchors should be installed a minimum of ten anchor diameters between each other and a minimum of five anchor diameters from the edge. *Drive pin dimensions are based on those originally published by the U.S. Anchor Corporation. 284
