Description
An anchoring device consisting of (A) an internally threaded conical expander designed with some means (ie. ribs or knurls) to prevent it from turning during expansion; and (B) an expansion sleeve which slips over the expander. The outer walls of the sleeve can be either straight cylindrical or tapered, and the surface either smooth or corrugated. A spherical steel lock washer at the top of the expansion sleeve is optional

Applications/ Advantages
A caulking type anchor which provides a quick setting in brick, concrete or stone. The lead shield's maleability enable it to fill uneven or irregular spots in the hole. When tamped, the expansion sleeve holds the expander inside the hole in the masonry, equally distributing the load around the anchor. Fixtures can be removed or replaced without sacrificing holding power

Material
Cone: May be one of the following materials: Brass, Malleable Iron, Steel or Die Cast Zinc Alloy; Expander Shield: Lead or 3-5% Antimonial Lead Alloy

Tensile and Shear Values
Machine screw anchors shall not be removable or show evidence of failure when subjected to tensil and shear test loads as specified in the above table. The suggested safe working load is one-fourth the average test proof loads
