Alcoa Fastening Systems (AFS) is now offering the NES Universal Rethreading System product line. The NES line is comprised of the NES Studsaver external and the NES ReTHRED internal thread restorers. NES tools can be purchased individually or as part of a kit featuring either the Studsaver or ReTHRED tools. Combination kits, containing tools for both internal and external thread repair, are also available.
The NES Studsaver is capable of re-threading virtually any stripped or damaged part. The tool adjusts to any thread diameter and pitch, adapts to all types of threads, and requires no prior measurement of the thread. Unlike taps, the Studsaver has the capability to enter below the damaged area and work outwards to complete the repair. The tool line is comprised of three tool variations, with a range spanning from 5/32” (M4) to 5” (M128). The Studsaver can be purchased on its own, or in a kit that includes a case, three sizes of Studsavers, one set of 60° replacement blades, internal thread cleaner, and an extension rod.
The NES ReTHRED utilizes a high-speed steel retracting blade to re-thread damaged internal threads from below the damaged area outward. This tool line is comprised of six tool variations, with a range of 5/16” (M8) to 2 5/8”(M68). The ReTHRED tool can adjust to any thread within its size range, tracking undamaged threads to regroove the damaged threads, all without prior measuring. Blades are available in 55° for BSP and BSW threadforms.
Fix-A-Thred repair kits and tooling are offered by Alcoa Fastening Systems, an Alcoa company. Alcoa Fastening Systems’ brands include Huck, Marson and Recoil. For more information, contact Alcoa Fastening Systems at (800) 826-2884, or online at www.alcoafasteningsystems.com.
