Title (EN) THREADED FASTENER, METHOD OF MAKING A THREADED FASTENER AND ROLLING DIES FOR MAKING A THREADED FASTENER
(FR) FIXATION FILETEE, PROCEDE DE FABRICATION CONNEXE ET ESTAMPES DE LAMINAGE UTILISEES DANS CE PROCEDE
Abstract:
(EN) A fastener (20) is described having a body comprising a substantially parallel portion (12) with a head (13) at one end and a tapered portion (14) leading to a point (15) at the other end, and a helical formation (21) providing an edge (23) along its length and extending outwardly from the body, wherein the helical formation (21) starts substantially at the point (15).
(FR) L'invention se rapporte à une fixation (20) présentant un corps comportant une partie (12) sensiblement parallèle; une tête (13), située au niveau d'une extrémité; une partie effilée (14) conduisant à une pointe (15), située au niveau de l'autre extrémité; et un élément en spirale (21) présentant une arête (23) longitudinale et s'étendant vers l'extérieur à partir du corps. L'enroulement de l'élément en spirale (21) commence sensiblement au niveau de la pointe (15).
