An improved method and system of temporarily attaching a frame to a masonry building structure. A circular base mount is inserted into a circular sleeve, that has been pre-drilled into masonry by a coring bit. The masonry core is left in place. The circular base has contact with the inner surface of the core, the outer surface of the core, and the top of the core. Adhesive is used to permanently cement the base mount to the masonry core, providing abundant surface area for extra holding power. The base mount has a hooked top web for permanent or temporary connection to a female mount that is held in place to the base mount by rotation and locking. The female mount can be attached to a shutter, providing protection against hurricane winds.

I claim: 1. A method of attaching a bracket to a solid, generally flat surface comprising: a. drilling into a surface using a standard coring-bit; b. removing the coring-bit, leaving a drilled-out annulus and a cylinder-shaped core; c. applying adhesive into said annulus and on top of said core; d.

I claim: 1. A method of attaching a bracket to a solid, generally flat surface comprising: a. drilling into a surface using a standard coring-bit; b. removing the coring-bit, leaving a drilled-out annulus and a cylinder-shaped core; c. applying adhesive into said annulus and on top of said core; d. applying a bracket having a generally open-can shape with cylinder-shaped sides that slide into the annulus and a generally flat surface that rests on top of the core; e. forming a strong bond with the adhesive between the inside surface of the cylinder and the surface of the core, and the outside surface of the cylinder and the outside surface of the drilled annulus, and between the top of the core and the flat surface of the bracket. 2. The method of claim 1 wherein the cylinder-shaped core left by the coring-bit allows a shallower depth than drilling a hole using a standard drill-bit. 3. The method of claim 1 wherein the drilled annulus would contain less volume than a drilled hole, therefore less material is removed from the surface using the coring-bit than when using the standard drill-bit. 4. The method of claim 1 wherein the coring-bit drills shallower and removes less material than a standard drill-bit, therefore less time is consumed when drilling with the coring-bit than when using the standard drill-bit. 5. The method of claim 1 wherein a standard rotary-drill can be used on the coring-bit when drilling in masonry, whereas an uncommon and expensive hammer-drill must be used with a standard drill-bit when drilling in masonry. 6. The method of claim 1 wherein the drilled annulus would contain less volume than a drilled hole, therefore less adhesive is used in filling a drilled-out annulus and core top, than in filling a standard drilled-out hole when using a standard drill-bit. 7. The method of claim 1 wherein friction between both walls of the annulus and the core holds the cylinder of the bracket in place while the adhesive is curing, whereas brackets in standard drill holes can lean to edges of the drilled hole. 8. The method of claim 1 wherein the surface area between the core and the inside of the cylinder, and the inside of the drilled annulus and the outside of the cylinder is much more than the surface area of a bolt inserted into a hole, drilled by a standard drill-bit. 9. A bracket for inserting into a drilled-out annulus, containing an inner core, drilled by a core-bit comprising: a. sides being shaped like a cylinder; b. one end of the cylinder being open; c. the open end of the cylinder having a generally smooth opening and diameter to fit over the core and into the annulus left by a coring bit; d. the thickness of said cylinder sides are sized to fit into said annulus; e. the other end of said cylinder is closed and the inside surface is flat; f. the outside of the closed end contains an attaching web; g. the attaching web having an attaching means for temporary or permanent holding of different types of fasteners that need to be secured to a generally flat surface. 10. The bracket of claim 9 wherein the diameter of the cylinder are generally equal to the diameter of a coring-bit, thereby the cylinder slides into the drilled-out annulus left by a coring bit. 11. The bracket of claim 9 wherein the open end of the cylinder, the sides of the cylinder, and the inner top of the bracket is attached to the drilled annulus and core by an adhesive. 12. The bracket of claim 9 wherein the adhesive has generally full contact with the cylinder sides and inner top of said bracket. 13. The bracket of claim 9 wherein the cylinder has at least one space for better gripping of the adhesive.
