PCT No. PCT/SE86/00395 Sec. 371 Date May 14, 1987 Sec. 102(e) Date May 14, 1987 PCT Filed Sep. 8, 1986 PCT Pub. No. WO87/02105 PCT Pub. Date Apr. 9, 1987.Sheet metal nails (2) are linked side-by-side with each other in a metal strip (1), the nails being parallel to each other and extending at an angle to the longitudinal direction of the strip from one lateral edge of the strip to the other opposite lateral edge. Each sheet nail (2) has a profiled nail shank (4) having at one end a head (5), a transition portion between the profiled shank (4) and the nail head (5) comprising a relatively gently curved portion (7) which is also profiled, the head being also profiled and no wider than the shank. The nail end remote from the head has a penetration portion with at least one point. The profiling of the nail shank (4), the curved portion (7) and the head (5) is such that these portions have substantially the same cross-sectional shape, the sheet metal in the nail being of substantially uniform thickness. The nails are joined to each other only by metal bridges that are spaced apart lengthwise of the nails, the nails being separate from each other between the bridges. |
