Stainless Steel 304/316 Set Anchor With hex nut, washer Concrete Anchor Bolts
Anchors achieve holding power either by "hooking" into the seabed, or via sheer mass, or a combination of the two. Permanent moorings use large masses (commonly a block or slab of concrete) resting on the seabed. Semi-permanent mooring anchors (such as mushroom anchors) and large ship's anchors derive a significant portion of their holding power from their mass, while also hooking or embedding in the bottom. Modern anchors for smaller vessels have metal flukes which hook on to rocks on the bottom or bury themselves in soft seabed.
The vessel is attached to the anchor by the rode (commonly called the anchor cable or anchor chain in larger vessels), which is made of chain, cable, rope, or a combination of these. The ratio of the length of rode to the water depth is known as the scope; generally, the rode should be between 5 and 10 times the depth of the seabed, giving a scope of 5:1 or 10:1; the larger the number, the shallower the angle is between the cable and the seafloor, and the less upwards force is acting on the anchor. A 10:1 scope gives the greatest holding power, but also allows for much more drifting due to the longer amount of cable paid out. Anchoring with sufficient scope and/or heavy chain rode brings the direction of strain close to parallel with the seabed. This is particularly important for light, modern anchors designed to bury in the bottom, where scopes of 5– to 7-to-1 are common, whereas heavy anchors and moorings can use a scope of 3-to-1, or less.
Since all anchors that embed themselves in the bottom require the strain to be along the seabed, anchors can be broken out of the bottom by shortening the rope until the vessel is directly above the anchor; at this point the anchor chain is "up and down", in naval parlance. If necessary, motoring slowly around the location of the anchor also helps dislodge it. Anchors are sometimes fitted with a tripping line attached to the crown, by which they can be unhooked from rocks or coral.
The term aweigh describes an anchor when it is hanging on the rope and is not resting on the bottom. This is linked to the term to weigh anchor, meaning to lift the anchor from the sea bed, allowing the ship or boat to move. An anchor is described as aweigh when it has been broken out of the bottom and is being hauled up to be stowed. Aweigh should not be confused with under way, which describes a vessel which is not moored to a dock or anchored, whether or not the vessel is moving through the water.

|1.Drill a hole through the mounting holes in the fixture or directly through the material to be fastened and into the base material, using a hammer drill and a carbide bit conforming to ANSI B94, 12-77 with the same size bit as the anchor diameter|
|2.Make sure nut is flush with the top threaded part of the anchor. Insert the sleeve anchor assembly through the mounting holes in the fixture and into the base material. Push the anchor assembly until the washer is snug against the fixture.|
|3.Turn the nut by hand until snugged up. Tighten the nut with a wrench (use a screwdriver for flat/round heads), approximately three or four full turns, or until the anchor is tightly secured to the base material.|
The length of the sleeve anchor should be equal to minimum embedment, plus fixture thickness, plus nut and washer. The Sleeve anchor requires no maximum hole depth. The depth of the hole in the base material should be at least the length of the sleeve anchor minus the thickness of the material being fastened. This will provide some extra depth to accommodate a minor amount of concrete cuttings which may not be able to be cleaned out of hole.
The forces on a Sleeve Anchor are transferred to the material in which it is installed. If the anchors are installed too close together, it can cause an interaction of the forces, thus reducing the holding power of the anchors. As a rule of thumb, the expansion anchor industry has established a minimum standard of ten (10) anchor diameters for spacing between anchors and five (5) anchor diameters from an unsupported edge. When vibration or sudden impact are part of the load conditions, the spacing should be increased.
