What is sleeve anchor?

The sleeve anchor,also called Dyna-Bolt, Sleeve-All, Power Bolt, and Thunder Sleeve is a type of fastener used to secure objects to a concrete or masonry structure. They can be used to join two or more concrete structures, or to fasten an object such as a shelf to a brick wall. Sleeve anchors are also referred to as two-step bolts or anchor bolts in some areas.

The sleeve anchor consists of a solid metal screw or stud with a cone-shaped tip that flares out to the sides. A metal sleeve wraps around the outside of the stud, allowing the tip of the stud to extend out the end of the sleeve. A washer and nut sit at the top of the bolt for adjustment and installation. Once the sleeve anchor has been inserted into concrete, installers turn the nut to pull the stud up into the sleeve. As the flared end of the stud passes into the sleeve, it causes the sleeve to expand outward and grasp the concrete for a secure hold.
