Maximum Strength Anchoring Guidelines
Specifications
Description — ALLIGATOR Solid-Wall Anchors
Material — specially formulated grade of self-lubricating, translucent polypropylene
Screw specification — see chart below
[NOTE: only the threaded portion of the screw should be in the anchor itself; any unthreaded shank portion of the screw
may be in the fixture or item being anchored, but not in the anchor]

• The anchors should be installed at least 1.5"
(39mm) from an unsupported edge in high-
strength materials, because of the high
compression forces exerted by the screw.
• With lag bolts, do not permit the unthreaded
portion to enter the anchor. Any unthreaded
portion should remain in the item being
anchored.
• Use hex head screws wherever possible,
because of high back pressure.
The screw diameter changes the compressive force of the anchor asembly. This allows the same diameter anchor, when used with
different screw diameters, to work in all kinds of substrates. Small diameter screws should be used in low-strength, easily compressed
substrates. Large diameter screws should be used in high-strength substrates. When used in porous masonry materials such as low
compressive strength concrete, aerated concrete, small unsupported blocks, or brick, it is recommended that the screw size not
exceed those given in the chart above. Use hardened or stainless steel screws to increase shear and tensile strength.
Screws or lag bolts used with ALLIGATOR anchors do not directly engage the surrounding masonry material. As a result, screws
anchored with ALLIGATOR anchors have very high residual holding strength and low susceptibility to failure by vibration or shock
loads. Even the maximum size screws do little, if any, damage when pulled out. The same hole can usually be reused without any
lessening of anchoring strength.
Drill insertions holes
twice anchor length. Drilled hole length + thickness of fixture should exceed screw length by a minimum of 1/2".
