High Low Thread Forming Screws
High Low Thread Forming Screws have a double-lead, consisting of a high and low thread. The high thread is sharper and flatter than a standard thread. High Low Screws are ideal for use in plastic, nylon or other low-density materials. The High Low thread design reduces driving torque, improves pullout strength and enhances the resistance to thread stripping. Fastener SuperStore offers over 500 distinct size and style combinations. Our High Low Screws are offered in multiple head and drive styles, materials and finishes.
