Cut and Roll Threading
More threading options means faster delivery!
With three roll threaders and fourteen cut threaders, Portland Bolt can thread fasteners for all kinds of projects. Our experienced operators ensure you are delivered quality threaded product that won’t gall or resist a nut, even after galvanizing. Over a century of threading fasteners has resulted in two efficient and cost-effective threading methods capable of handling steel up to 6” in diameter.
Roll Threading (through 1” diameter)
Roll threading is an extrusion process in which steel round bar is forced between two dies to form the threaded portion of a fastener, instead of being removed as in cut threading.
Cut Threading (through 6” diameter)
Cut threading is a process by which steel is cut away from a round bar of steel to form the threads. This process is more labor-intensive than roll threading but provides more flexibility with regard to longer thread lengths and larger diameters.
