PACKAGING ELEMENTS; PACKAGES ## Abstract An interchangeable fastener system for use in combination with a perforated board or other surface on a vertical plane includes a main fastener including a base for supporting the main fastener on the perforated board; the base surrounding a channel defined by inner surfaces including opposing ramp surfaces to facilitate tightening of an attachment member, and a mechanical stop adjacent each ramp surface to prevent over rotation of the attachment member; and the attachment member including an insertion member having a first end tab and a second end tab, wherein the insertion member is sized and configured for selective passage through the channel from the front surface and wherein the attachment member may be selectively rotated until a male detent mates with a female detent for securing the attachment member to the main fastener. ## Claims ### Claim 1 An interchangeable fastener system for use in combination with a perforated board having a plurality of openings thereon, the interchangeable fastener system comprising: a main fastener including a base having a rear surface and a front surface; a plurality of counterbored holes formed on the base, each of the plurality of counterbored holes being relieved for engaged receipt of a corresponding one of a plurality of push grommets, and each of the plurality of grommets being sized and configured for engaged passage through a corresponding one of the plurality of openings on the perforated board for supporting the main fastener on the perforated board; the base surrounding a channel defined by a plurality of inner surfaces extending between open ends at the rear surface and front surface of the base and between the front surface of the base and a backing member; the inner surfaces further including opposing ramp surfaces extending between the counterbored holes to facilitate tightening of an attachment member; the attachment member including an insertion member having a first end tab and a second end tab, wherein the insertion member is sized and configured for selective passage through the channel from the front surface and wherein the attachment member may be selectively rotated until a male detent mates with a female detent for securing the attachment member to the main fastener; and a cylindrical bore formed on the base, the cylindrical bore being sized and configured for centering the attachment member within the channel. ### Claim 2 (depends on 1) The interchangeable fastener system as recited in claim 1 wherein the attachment member is a clamp member sized and configured for engaged receipt of a container. ### Claim 3 (depends on 1) The interchangeable fastener system as recited in claim 1 wherein the attachment member is a spring clamp member. ### Claim 4 (depends on 1) The interchangeable fastener system as recited in claim 1 wherein the attachment member is a hook member. ### Claim 5 (depends on 1) The interchangeable fastener system as recited in claim 1 wherein the attachment member is a loop member. ### Claim 6 (depends on 1) The interchangeable fastener system as recited in claim 1 wherein the attachment member is a magnetic member. ### Claim 7 (depends on 1) The interchangeable fastener system as recited in claim 1 wherein the attachment member is a spool holder member. ### Claim 8 An interchangeable fastener system for use in combination with a perforated board having a plurality of openings thereon, the interchangeable fastener system comprising: a main fastener including a base having a rear surface and a front surface; a plurality of counterbored holes formed on the base, each of the plurality of counterbored holes being relieved for engaged receipt of a corresponding one of a plurality of push grommets, and each of the plurality of grommets being sized and configured for engaged passage through a corresponding one of the plurality of openings on the perforated board for supporting the main fastener on the perforated board; the base surrounding a channel defined by a plurality of inner surfaces extending between open ends at the rear surface and front surface of the base and between the front surface of the base and a backing member; the inner surfaces further including opposing ramp surfaces extending between the counterbored holes to facilitate tightening of an attachment member, and a mechanical stop adjacent each ramp surface to prevent over rotation of the attachment member; the attachment member including an insertion member having a first end tab and a second end tab, wherein the insertion member is sized and configured for selective passage through the channel from the front surface and wherein the attachment member may be selectively rotated so that the first and second end tabs are each in engaged abutment against a corresponding one of the opposing ramp surfaces and mechanical stops; and a cylindrical bore formed on the base, the cylindrical bore being sized and configured for centering the attachment member within the channel. ### Claim 9 (depends on 8) The interchangeable fastener system as recited in claim 8 wherein the attachment member is a clamp member sized and configured for engaged receipt of a container. ### Claim 10 (depends on 8) The interchangeable fastener system as recited in claim 8 wherein the attachment member is a spring clamp member. ### Claim 11 (depends on 8) The interchangeable fastener system as recited in claim 8 wherein the attachment member is a hook member. ### Claim 12 (depends on 8) The interchangeable fastener system as recited in claim 8 wherein the attachment member is a loop member. ### Claim 13 (depends on 8) The interchangeable fastener system as recited in claim 8 wherein the attachment member is a magnetic member. ### Claim 14 (depends on 8) The interchangeable fastener system as recited in claim 8 wherein the attachment member is a spool holder member. ### Claim 15 An interchangeable fastener system for use in combination with a perforated board having a plurality of openings thereon, the interchangeable fastener system comprising: a main fastener including a base having a rear surface and a front surface; a plurality of grommets being sized and configured for engaged passage through a corresponding one of the plurality of openings on the perforated board for supporting the main fastener on the perforated board; the base surrounding a channel defined by a surface extending between open ends at the rear surface and front surface of the base; the surface including opposing ramp surfaces extending between the counterbored holes to facilitate tightening of an attachment member; and the attachment member including an insertion member having a first end tab and a second end tab, wherein the insertion member is sized and configured for selective passage through the channel from the front surface and wherein the attachment member may be selectively rotated so that the first and second end tabs are each in engaged abutment against a corresponding one of the opposing ramp surfaces. ### Claim 16 (depends on 15) The interchangeable fastener system as recited in claim 15 wherein the attachment member is a clamp member sized and configured for engaged receipt of a container. ### Claim 17 (depends on 15) The interchangeable fastener system as recited in claim 15 wherein the attachment member is a spring clamp member. ### Claim 18 (depends on 15) The interchangeable fastener system as recited in claim 15 wherein the attachment member is a hook member. ### Claim 19 (depends on 15) The interchangeable fastener system as recited in claim 15 wherein the attachment member is a loop member. ### Claim 20 (depends on 15) The interchangeable fastener system as recited in claim 15 wherein the attachment member is a magnetic member. ### Claim 21 (depends on 15) The interchangeable fastener system as recited in claim 15 wherein the attachment member is a spool holder member.
