An improved fastener for attaching metal to wood is described. The fastener is particularly suited for use as a railroad spike for attaching a metal rail to a wooden tie. The improved spike is adapted for installation by either driving or screwing the spike into the tie. A plurality of flutes are adapted to engage with the tie, thereby preventing loosening of the spike. The spike may be used with or without a metal boss or fishplate to secure a metal rail to a wooden tie.

La présente invention concerne une fixation améliorée permettant d'attacher du métal à du bois. Cette fixation est notamment adaptée à un usage en tant que crampon de voie ferrée permettant d'attacher un rail métallique à une traverse en bois. Ce crampon amélioré est conçu pour être installé soit en enfonçant ou en vissant le crampon dans la traverse. Une pluralité de cannelures sont conçues pour venir en prise avec la traverse, ce qui empêche le crampon de se desserrer. Le crampon selon cette invention peut être utilisé avec ou sans un bossage métallique ou éclisse afin de fixer un rail métallique sur une traverse en bois.
