Description

A roofing material fastener comprises a shank having a length dimension and a point. The shank is adapted to enable it to be driven through at least a first course of roofing material and into a roof deck. A fastener head is positioned in a region of the shank distal from the point. A spike protrusion projects from the distal region of the shank to a terminus. The length of the spike protrusion is less than one half the length of the shank, measured from the point to the fastener head. The spike protrusion is adapted to penetrate a depth less than the full depth of a second course of roofing material installed above the first course. The spike protrusion is shaped to inhibit sawing through the second course of roofing material by the spike protrusion.

L'invention concerne une attache pour matériau de couverture comprenant une tige ayant une dimension de longueur et un point. La tige est adaptée pour lui permettre d'être entraînée à travers au moins une première course de matériau de couverture et dans un platelage de toit. Une tête d'attache est placée dans une région de la tige à distance du point. Une protubérance de pointe fait saillie de la région distale de la tige vers une extrémité. La longueur de la protubérance de pointe est inférieure à une moitié de la longueur de la tige, mesurée du point à la tête d'attache. La protubérance de pointe est adaptée pour pénétrer une profondeur inférieure à la profondeur entière d'une seconde course de matériau de couverture installée au-dessus de la première course. La protubérance de pointe est formée pour inhiber le sciage à travers la seconde course de matériau de couverture par la protubérance de pointe.
