Purchase Concrete Sleeve Anchors
Technical Information:
The Sleeve Anchor is constructed of high quality steel parts. Each part is zinc plated and assembled into a complete ready-to-use anchor. The anchor consists of a threaded stud with an outwardly flared cone-shaped end. A tubular expander sleeve is assembled over the stud and butted
against the small diameter of the cone. A washer and hex nut are then assembled on the stud to complete the anchor. The anchor works on a true expansion principle: Tightening of the nut pulls the cone-shaped stud end into the expander sleeve, wedging it outward and locking the anchor into
the base material.
Concrete Sleeve Anchor - Approvals:
- Listed by Underwriters Laboratories (UL)
- Board of Standards and Appeals (BSA), City of NY
- Meets or exceeds U.S. Government G.S.A. Specifications FF-S-325, Group II, Type 3, Class 3
Concrete Sleeve Anchor - Applications:
Light to medium-duty into concrete, brick and block.
Concrete Sleeve Anchor – Installation:
- 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.
- Clear hole of all debris.
- 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.
- 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.
Concrete Sleeve Anchor - Anchor Length:
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.
Concrete Sleeve Anchor - Anchor Spacing:
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.
