Anchor bolts

What are anchor bolts?

Anchor bolts are used to attach structural and non-structural components to concrete. Anchor bolts (also known as fasteners), steel plates, or stiffeners are just a few examples of the various parts that can be used to join two objects. Shear forces and tension forces are two different types of loads that anchor bolts can convey. Steel columns fastened to a reinforced concrete foundation can serve as a visual representation of the link between structural elements. The connection between the facade system and a structural steel wall is a typical example of a non-structural element being joined to a structural one.

What are anchors used for?

Anchor bolts are used for the purpose of securely fastening building elements to concrete. Anchor bolts are a common tool used in our industry for the purpose of attaching steel to concrete. While the first end is embedded in the concrete, the other end features threading that allows it to be attached to structural support. Anchor bolts are available in the following four different shapes: swedge, headed, L, and double-ended rods with plates. Each subtype possesses a distinct set of applications, dimensions, and advantages.

Can you over tighten toggle bolts?

To attach your fastener to the toggle bolt, slip it on. After that, you will need to thread the butterfly onto the bolt, squeeze it, and then pass it through the hole until you can feel the butterfly opening up. First, use your fingers to turn the bolt clockwise, and then complete the process with a screwdriver. It is important not to overtighten the bolt because doing so could cause the plaster to break.

What is the difference between wedge anchor bolt and expansion bolt?

The only anchors that can be used in solid concrete are the wedge, drop-in, and concrete striking anchors, which also have the highest and most reliable holding properties. Although they can be utilized in concrete, brick, or block, concrete sleeve anchors have lower holding characteristics in terms of shear and pullout values.

An expansion anchor bolt will expand as it goes through the hole. The anchor bolt and the object or structural component to which it is linked are held firmly in place thanks to its expansion. Because it is inserted in a pre-drilled hole, an expansion bolt is technically a form of the post-installed anchor bolt.

How do you install an anchor bolt?

• Utilizing a carbide-tipped bit that complies with ANSI requirements, drill a hole into the concrete.
• To ensure that the minimum embedment criteria are met, drill a hole that is 1/2″ deeper than the anchor and will pierce the concrete.
• While the fixture is in place, the hole can be drilled.
• Use a wire brush, pressurized air, a vacuum, a blowout bulb, or a similar tool to clean the hole.
• Make sure the nut is on the last threads before attaching the washer and nut to the wedge anchor.
• Put the wedge anchor into the hole in the fixture and the base material’s hole. Use a hammer to finish the installation until the nut and washer are snugs against the fixture—this should be a very tight fit.
• When the nut is finger-tight, turn it clockwise.

How much weight can a molly bolt hold?

These drywall anchors are not as simple to use as some of the others, but they are still useful to have around for loads ranging from medium (10 to 25 pounds) to heavy (above 25 pounds) (25 pounds to 50 pounds). A pointed molly (seen on the right) can be secured in its position using a hammer. Versions without points call for an installation hole and function admirably on walls constructed of old plaster and lath.
