External Hex Hexagon Expansion Screw Sleeve Concrete Anchor Bolt
These stainless steel anchors have good chemical resistance and may be mildly magnetic. Also known as drop-in anchors, they're often used for overhead applications because the anchor's internal plug expands in four directions to hold the anchor firmly inside the hole before inserting a threaded rod or bolt. To install, place the anchor into the hole, insert the required installation tool (sold separately) into the anchor, and drive with a hammer until the thicker portion of the tool makes contact with the anchor. When installed, anchors sit flush with the surface. Pull-out strength and shear strength values are 25% of the ultimate values.

What is a Expansion bolt
Anchor bolts are used to connect structural and non-structural elements to the concrete.The connection is made by an assembling of different components such as: anchor bolts (also named fasteners), steel plates, stiffeners. Anchor bolts transfer different types of load: tension forces and shear forces.A connection between structural elements can be represented by steel column attached to reinforced concrete foundation.Whereas, a common case of non-structural element attached to a structural one is represented by the connection between a facade system and a reinforced concrete wall.

Flange head screws
1) Expansion bolts can be used tosecure heavy objects to walls or floors. 2) Can handle vertical and horizontalloads. 3) By tightening the bolt, the nut on theopposite end pulls into the shell.expanding it outward and wedging itinside the hole in the wall or floor.
Using Effects
Expansion bolt
1. Using a hammer drill and carbide tipped drill bit, drill a hole the same diameter as the anchor diameter, and at least 1/2" to 1” deeper than the expected embedment.
2. Clean out the hole of all debris.
3. Set the nut flush with the top of the sleeve anchor.
4. Insert the sleeve anchor through the fixture into the hole in the base material until the washer and nut is tight against the
fixture.
5. Turn the nut until finger tight.
6. Use a wrench to set the anchor by turning the nut three to four full turns
