In one aspect, a holder mountable to a friable substrate may include a self-drilling drywall fastener, a wall engaging base plate having an opening for receiving a fastener, and at least one leg extending from the base plate for holding an object. In another aspect, a holder may include a self-drilling drywall fastener having a drilling portion longer than a drywall thickness followed by a high-threaded portion, a wall engaging base plate, and at least one leg for holding an object. In still another aspect, a holder may include a self-drilling drywall fastener having a screw-like drilling portion longer than a drywall thickness followed by a high-threaded portion, a drywall engaging base plate having a recess for receiving a rotary driver and a pair of openings each capable of receiving a threaded drywall fastener and engaging threads thereof.

What is claimed is: 1. A holder assembly mountable to a friable substrate comprising: at least two self-drilling drywall fasteners, each having an axis, a head, exterior threading for engaging said friable substrate, a proximal end, and a drilling end; a base plate having a center, wherein said base plate has at least two openings located above said center to receive said drywall fasteners, wherein for each of said drywall fasteners said threading of said proximal end has a crest diameter of at least about ¼ inch, and wherein each of said openings admits said threading of a corresponding one of said fasteners, said base plate being wider than a largest outside diameter of said exterior threading, and a leg located below said center, whereby said leg is supported by a thicker portion of said base plate, and wherein said leg is positioned for holding an object; and a second leg extending from said base plate below said center to form a pair of legs, wherein said pair of legs forms a U-shape for holding said object; wherein each of said legs has a distal portion and at least one stop between said base plate and said distal portion wherein said leg and said second leg extend from said thicker portion, said at least two openings are located on a comparatively recessed portion of said base plate, said U-shape formed by said legs includes a portion joining said legs that includes at least a portion having a thickness greater than said thicker portion and a generally continuous surface on an inner side of said U-shape, and said thicker portion is larger than said comparatively recessed portion. 2. A holder assembly according to claim 1, wherein each of said openings engages said head of said corresponding fastener. 3. A holder assembly according to claim 1, wherein each of said drywall fasteners further comprises a recess for a rotary driver and a screw-like drilling portion capable of drilling into a stud. 4. A holder assembly according to claim 1, wherein said pair of legs are generally aligned in a horizontal plane, and are generally symmetrical. 5. A holder assembly according to claim 1, wherein each of said legs has a foot. 6. A holder assembly according to claim 5, wherein each of said legs has at least one groove between said base plate and said foot. 7. A holder assembly according to claim 1, wherein said holder is cast from zinc. 8. A holder assembly according to claim 1, wherein each of said drywall fasteners comprises a solid body and has a drilling portion having a length longer than a thickness of said friable substrate. 9. A holder according to claim 1, said base plate further comprising a rearwardly projecting tang above at least one hole to pre-position the holder on a wall surface. 10. A holder assembly according to claim 1, wherein said base plate has a longitudinal axis, and wherein said center, said openings and said leg are all aligned with said axis. 11. A holder mountable to drywall and a stud, comprising: a self-drilling drywall fastener having an axis, a solid body, a screw-like drilling portion having a length longer than a thickness of said drywall and a high-threaded drywall engaging proximal portion, and an enlarged head, wherein said high-threaded proximal portion has threading having a crest diameter of at least about ¼ inch; a wall-contacting base plate substantially wider than a largest outside diameter of said proximal portion, wherein said base plate has a center and a pair of openings located above said center, each of said openings being capable of receiving a threaded drywall fastener and engaging the head thereof; and a U-shaped pair of legs for holding an object, wherein each one of said legs extends from a thicker portion of said base plate, below said center of said base plate to a distal portion having a foot; wherein said U-shape includes a portion joining said legs that includes at least a portion having a thickness greater than said thicker portion and a generally continuous surface on an inner side of said U-shape; and further wherein a portion of each one of said legs is surrounded on a plurality of sides by said thicker portion. 12. A holder mountable to a friable substrate, comprising: a generally flat base plate having a generally oval peripheral shape having a center, said base plate having a thicker portion and a recessed area, wherein said thicker portion is larger than said recessed area, an opening formed in said recessed area, said opening being located above said center to receive a drywall fastener, wherein said opening is large enough to admit passage of a fastener having threading with a crest diameter of at least about ¼ inch, and a leg extending from said thicker portion of said base plate, whereby a portion of said leg is supported and surrounded on a plurality of sides by said thicker portion, wherein said leg is positioned below said center for holding an object and wherein said leg has an enlarged foot at a distal end of said leg; a second leg extending from said thicker portion of said base plate to form a pair of legs, wherein said pair of legs form a U-shape for holding said object, said U-shape including a portion joining said legs that includes at least a portion having a thickness greater than said thicker portion and a generally continuous surface on an inner side of said U-shape. 13. A holder according to claim 12, said base plate further comprising a rearwardly projecting tang to pre-position the holder on a wall surface. 14. A holder according to claim 12, wherein said base plate has a longitudinal axis, and wherein said center, said opening and said leg are all aligned with said axis. 15. A holder according to claim 12, further comprising a second opening formed in said recessed area of said base plate, wherein each opening is capable of receiving a drywall fastener. 16. A holder according to claim 14, wherein said pair of legs are generally aligned in a common plane. 17. A holder according to claim 12, wherein said pair of legs are generally symmetrical about said axis. 18. A holder according to claim 12, wherein each of said legs has a foot. 19. A holder according to claim 12, wherein each of said legs further comprises at least one stop between said base plate and said foot. 20.
