Purchase Sleeve Anchors

The acorn head Sleeve-All® sleeve anchor is Simpson Strong-Tie’s name for their sleeve anchor that is manufactured with an acorn nut in place of the standard hex nut. The acorn nut gives the Sleeve-All® sleeve anchor a finished look and is versatile because it can be used in most types of masonry such as concrete, block or brick.

Acorn Sleeve-All® - Finish and Material

The acorn Sleeve-All® sleeve anchor is available in both the standard zinc plated carbon steel as well as the 304 stainless steel. The anchor body meets minimum tensile strengths of 50,000 psi and the nut, washer and sleeve are made from the SAE J403 or ASTM A563 types of steel.

Acorn Sleeve-All® - Federal Specifications and Codes

Meets federal specification requirements A-A-1992A

Acorn Sleeve-All® - Available Diameters

The acorn Sleeve-All® sleeve anchor comes in one diameter of 1/4”. All 1/4” Sleeve-All® sleeve anchor have an acorn nut head and are not available with the standard hex nut.

Acorn Sleeve-All® - Available Lengths

The 1/4” acorn headed Sleeve-All® sleeve anchor is manufactured in two lengths. The length of the acorn headed Sleeve-All® sleeve anchor needed is determined by the thickness of the material that is being fastened down. The acorn Sleeve-All® sleeve anchor length is measured from under the head of the acorn nut and washer.

Acorn Sleeve-All® - Minimum Embedment

The minimum embedment for the 1/4” acorn Sleeve-All® sleeve anchor is determined by the maximum fixture thickness. Subtracting the maximum fixture thickness of the overall length of the sleeve anchor gives the minimum embedment depth for each diameter of acorn Sleeve-All® sleeve anchor. The maximum thickness of material for embedment for the 1-3/8” long acorn Sleeve-All® sleeve anchor is 1/4” and the maximum thickness for the 2-1/4” long Sleeve-All® sleeve anchor is 1-1/8”. (See chart below.)

Acorn Sleeve-All® - Diameter of Hole

Hole size is equal to the diameter of the acorn Sleeve-All® sleeve anchor. The 1/4” acorn Sleeve-All® sleeve anchor requires a 1/4” hole to be drilled into the base material. Hole size is critical because an oversized hole may make it impossible for the acorn Sleeve-All® sleeve anchor to be set which will cause the holding values to be reduced. When drilling a hole into the base material, use an ANSI standard bit supplied in a hammer drill to ensure hole quality and tolerance.

Acorn Sleeve-All® - Length of Hole

When drilling a hole for an acorn Sleeve-All® sleeve anchor into the base material, drill the hole 1/4” to 1/2” deeper than the sleeve anchor will penetrate. This will leave room for any dust or debris that may be created during the installation process.
Acorn Sleeve-All® - Diameter of Hole in Fixture
The hole in the fixture that the sleeve anchor will go through must be larger than the designated diameter of the acorn Sleeve-All® sleeve anchor being used. Most holes in fixtures are true diameters, but concrete anchors have a designated diameter of the anchor slightly larger than the true diameter. The hole in the fixture needs to be a minimum of 1/8” larger than the diameter of the acorn sleeve anchor being installed.

Acorn Sleeve-All® - Installing

1. Drill a hole in the base material using a hammer drill and a 1/4” ANSI standard carbide bit. Drill the hole deep enough so that the hole will be a minimum of 1/4” deeper than the acorn Sleeve-All® sleeve anchor will penetrate.

2. Compressed air should be used to clean out the hole.

3. Push the acorn Sleeve-All® sleeve anchor through the hole in the fixture and into the hole drilled in the base material, until the acorn nut and washer are flush with the surface of the fixture.

4. Use a wrench to turn the acorn nut clockwise until tight.
