A structured surface, which includes a thermoplastic backing sheet and a first upstanding element, is disclosed. The first upstanding element includes multiple, spaced-apart posts and a single cap at the distal ends of the multiple, spaced-apart posts. The structured surface furthermore typically includes a plurality of spaced-apart, upstanding posts with caps on their distal ends, where the ratio of the caps to the posts is less than one-to-one. Also disclosed is a method of making a structured surface. The method includes providing a thermoplastic backing sheet with a plurality of spaced-apart, upstanding posts; and deforming the distal ends to form caps on at least some of the spaced-apart, upstanding posts. At least some of the caps upon forming touch at least one adjacent cap to form a conjoined cap at the distal ends of multiple posts.

1. A structured surface comprising: a thermoplastic backing sheet;multiple, spaced-apart posts having proximal and distal ends, wherein the proximal ends directly attached to the thermoplastic backing sheet, and wherein at least some of the multiple, spaced-apart posts are not uniformly spaced on the thermoplastic backing sheet; anda first upstanding male fastening element comprising: at least two of the multiple, spaced-apart posts having proximal and distal ends, with the proximal ends directly attached to the thermoplastic backing sheet; anda single cap at the distal ends of the at least two of the multiple, spared-apart posts. 2. A structured surface according to claim 1 further comprising a second upstanding male fastening element comprising a single post of the multiple, spaced-apart posts with one cap on the distal end of the single post. 3. A structured surface according to claim 2, wherein at least one of the multiple-spaced apart posts of the first upstanding male fastening element has a different cross-sectional area from the single post of the second upstanding male fastening element. 4. A structured surface according to claim 1, wherein the multiple, spaced-apart posts of the first upstanding male fastening element have different cross-sectional areas. 5. A structured surface according to claim 1, wherein the single cap has a perimeter with at least one segment of concavity, or wherein the single cap comprises a through hole. 6. A structured surface according to claim 1, wherein the single cap has a multi-lobed shape. 7. A structured surface according to claim 1, wherein the thermoplastic backing sheet is a web. 8. A structured surface according to claim 7, wherein the web is wound into a roll. 9. A structured surface comprising: a thermoplastic backing sheet having no holes; anda plurality of male fastening elements with posts having proximal and distal ends, with the proximal ends directly attached to the thermoplastic backing sheet and with caps on the distal ends,wherein at least some of the male fastening elements comprise at least three spaced-apart posts and a single cap at the distal ends of the at least three spaced-apart posts. 10. A structured surface comprising: a thermoplastic backing sheet; anda plurality of spaced-apart upstanding posts having proximal and distal ends, with the proximal ends attached directly to the thermoplastic backing sheet and with caps on the distal ends,wherein at least some of the spaced-apart, upstanding posts are not uniformly spaced on the thermoplastic backing, and wherein for at least some of upstanding posts with caps, more than one post supports a single cap. 11. A structured surface according to claim 10, wherein the structured surface is a mechanical fastener. 12. A method of making a structured surface, the method comprising: providing a thermoplastic backing sheet with a plurality of spaced-apart, upstanding posts having proximal and distal ends, wherein the proximal ends are directly attached to the thermoplastic backing sheet, and wherein at least a portion of the plurality of spaced-apart, upstanding posts is not uniformly spaced on the thermoplastic backing sheet: anddeforming the distal ends to form caps on at least some of the spaced-apart, upstanding posts, wherein at least some of the caps upon forming touch at least one adjacent cap to form a conjoined cap at the distal ends of multiple posts. 13. A method according to claim 12, wherein the at least some caps upon forming are shaped at least partially by the at least one adjacent cap. 14. A method according to claim 12, wherein at least some of the caps upon forming do not touch at least one adjacent cap. 15. A method according to claim 12, wherein the conjoined cap has at least three posts. 16. A method according to claim 12, wherein the cojoined cap has a perimeter with at least one segment of concavity, or wherein the conjoined cap comprises a through-hole. 17. A method according to claim 16, wherein the conjoined cap has a multi-lobed shape. 18. A method according to claim 12, wherein at least some of the posts in the plurality of spaced-apart, upstanding posts have at least one of different shapes or different cross-sectional areas. 19. A structured surface comprising: a thermoplastic backing sheet, having no holes; anda plurality of male fastening elements with posts having proximal and distal ends, with the proximal ends directly attached to the thermoplastic backing sheet and with caps on the distal ends,wherein at least some of the male fastening elements comprise at least two spaced-apart posts and a single cap at the distal ends of at least two spaced-apart posts. 20. A structured surface according to claim 19, wherein at least some of the caps have a perimeter with at least one segment of concavity, or wherein at least some of the caps comprise a through-hole.
