Lang Tools 2584 15-Piece Metric Thread Restorer Set, Black, Gray

Product Information

General Tools one of the oldest USA tool manufactures with an extensive range of quality products for professional use. When a threaded hole becomes worn or stripped there are two highly effective options for restoring the threads to original holding potential. The simplest of these and maybe most well known, is the HeliCoil insert which looks like a spring but once installed creates a new thread within a thread. The concept is simple enough. Imagine a male thread on a screw or bolt is like a spring wrapped around a smooth bar and a female thread, a spring inserted into a smooth bore. When a thread gets stripped, it’s as if that spring is being removed and in some cases, that’s exactly what it looks like. It’s not uncommon for a stud to pull out of an alloy casting with the aluminium thread still fitting neatly and yes, a little annoyingly, into its spiral grooves, just like a spring.

The reason its so important to identify the thread pitch correctly is because there are fractional and metric threads that are close to being the same. However, if you choose a thread restoration file with the wrong pitch you will end up damaging the threads even more. If you only have one size thread that needs to be repaired the E-Z Lok Helical Threaded Insert Kit is a smart choice. You only pay for the tools and inserts you need for the repair job at hand. The Lang 972 40 Piece Fractional and Metric Thread Restorer Kit is very practical option for restoring Fractional and Metric male or female threads. The tooling in this kit is very high quality and machined to ANSI Standards from heat-treated tool steel. Once thee hole has been tapped the Helicoil is inserted on the special installation tool and started in the tapped hole.Keep in mind this set is NOT for cutting new threads. The taps or dies are designed to reform existing damaged threads without removing metal.

Once the threads are forced out of the helix it becomes very difficult or impossible to continue turning the nut or stud. If turning is continued the threads are very likely to become ceased, destroying the male and female threads beyond repair. However, if there is minimal damage to the threads they can be restored to their original configuration and in most cases to original holding strength.The Heli-Coil ® Sav-A-Thread ® HT kit is a professional spark plug thread repair kit that is typically used in 4.6 and 5.4 liter Ford ® engines, and offers the highest quality and most durable repair available to permanently restore stripped spark plug hole threads.
