Flat headed Sleeve-All® sleeve anchors
are manufactured by Simpson Strong-Tie and are sleeve anchors with a
flat phillips countersunk head. Flat head Sleeve-All® sleeve anchors
are used in applications where the head of the fastener needs to be
countersunk and flush with the surface of the material being fastened.
Examples of this type of application are metal doorframes to a concrete
or block wall, or metal thresholds to concrete.
Flat Sleeve-All® - Finish and Material
The flat Sleeve-All® sleeve anchor is available in standard zinc
plated carbon steel and a type 304 stainless steel. The body of the
anchor 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.
Flat Sleeve-All® - Federal Specifications
Meets or exceeds federal specification requirements A-A-1992A
Flat Sleeve-All® - Available Diameters
The flat Sleeve-All® sleeve anchors are available in 3 diameters
of 1/4”, 5/16” and 3/8”. The flat headed Sleeve-All® sleeve anchors
have a phillips drive #2 for the 1/4” and 5/16” and # 3 for the 3/8”.
Flat Sleeve-All® - Available Lengths
The 1/4” and 5/16” flat headed Sleeve-All® sleeve anchors are
manufactured in two lengths and the 3/8” flat head sleeve anchor is
available in four lengths. The length of the flat-headed sleeve anchor
to be used in any particular application is determined by adding the
thickness of the material being fastened to the minimum embedment for
the diameter of flat sleeve anchor being used. The length of the flat
Sleeve-All® sleeve anchor is measured as an overall length of the
anchor, including the head.
Flat Sleeve-All® - Minimum Embedment
The minimum embedment for each of the flat head Sleeve-All®
sleeve anchor is determined by the diameter of the flat headed
Sleeve-All® sleeve anchor being used for any particular application.
Larger diameter sizes require deeper embedment into the base material
for the anchor to achieve minimum holding values. See Chart B below for
the maximum thickness of a fixture for each diameter and length of flat
headed Sleeve-All® sleeve anchor.
Flat Sleeve-All® - Diameter of Hole
The hole diameter to be drilled into the base material is the
same diameter as the flat Sleeve-All® sleeve anchor being installed.
The 1/4” flat Sleeve-All® sleeve anchor needs a 1/4” hole, the 5/16”
anchor needs a 5/16” hole and the 3/8” anchor needs a 3/8” hole. The
hole size is critical for all expansion type anchors because an
oversized hole will make it difficult for the anchor to expand properly
and the holding values will be compromised.
Hole size is equal to the diameter of the acorn Sleeve-All® sleeve
anchor. To insure that the hole is the proper size it is very
important to use a carbide bit that meets ANSI standards and that the
hole is drilled using a hammer type drill.
Flat Sleeve-All® - Length of Hole
The depth of the hole in the base material should be 1/4” to 1/2”
deeper in the base material than the flat Sleeve-All® sleeve anchor
will penetrate. This extra space is needed to hold the dust or debris
that is created during the installation process that might prevent the
proper expansion of the flat Sleeve-All® sleeve anchor.
Flat Sleeve-All® - Diameter of Hole in Fixture
Concrete expansion anchors designated diameters are larger than
the true diameter, for example a 3/8” diameter flat Sleeve-All® sleeve
anchor is larger than 3/8”. It is critical that the hole in the fixture
is large enough for the flat Sleeve-All® sleeve anchor being used to
fit through. The hole in the fixture needs to be about 1/8” larger in
diameter than the flat Sleeve-All® sleeve anchor being used to insure
enough clearance.
Flat Sleeve-All® - Installing
1. Using a hammer drill and a 1/4” ANSI standard carbide bit,
drill a hole in the base material deep enough so that the hole will be a
minimum of 1/4” deeper than the flat Sleeve-All® sleeve anchor will go
into the base material.
2. Compressed air or a blowout bulb should be used to clean out the hole.
3. Unscrew the flat head of the sleeve anchor so that it allows just a couple of threads to be threaded.
4. Insert the flat Sleeve-All® sleeve anchor through the hole in
the fixture and into the hole drilled in the base material until the
head of the flat Sleeve-All® sleeve anchor is flush with the surface of
the fixture.
5. Use a slotted or phillips screw driver to turn the head clockwise until snug.
