A device for giving stability to one part of a structure by making it fast to another consisting of (A) A threaded stud with a conical end flared outward; (B) A hollow, cylindrical dilating sleeve assembled over the stud and positioned against the minor diameter of the cone; (C) A washer and hex nut assembled at the end opposite the cone.
The sleeve anchor works by expanding against the material in which it is embedded. When the hex nut is tightened conical end is pulled into the dilating sleeve psuhing it outward 360° around the anchor into the masonry. They are designed to be used in solide or hollow masonry, including cinder block, brick, marble and concrete. One advantage of the sleeve anchor is that it can be removed after it’s been installed. Another is that the length of the sleeve induces less stress on the substrate than does a wedge anchor. It is well-suited for permanently anchoring heavy equipment to conrete.
MATERIAL: Carbon and stainless steel
FINISH: Carbon Steel: Zinc plated
Caution: Oversized holes will make it difficult to set the anchor and will reduce the anchor’s load capacity.
• Drill a hole in the base material using a carbide drill bit the same diameter as the nominal diameter of the anchor to be installed. Drill the hole to the specified embedment depth and blow it clean using compressed air. Overhead installations need not be blown clean. Alternatively, drill the hole deep enough to accommodate embedment depth and dust from drilling.
• Place the anchor in the fixture and drive into the hole until the washer and nut are tight against fixture.
• Tighten to required installation torque.
Sleeve-All Installation Data
