Its high-speed steel cutter ensures durability, making it a space-efficient alternative to traditional threading tools. ## Description Product Description The NES 21 is a universal internal thread repair tool. This easy-to-use tool operates by adjusting the knob that sets the proper internal diameter of the tool to the good thread below the damaged thread and the 60 degree blade floats to the correct pitch. The NES 21 has a working capacity from 5/16 in. to 7/16 in. NES External and Internal thread restorers are the ideal tools for saving money during maintenance, plumbing, construction, agriculture, car repair and many other applications where there are components with a damaged thread. Compare the cost of disassembling the part in order to repair a component with the INSTANT repair that need to be performed with the NES External and NES Interal thread restorers.

Our patented tools are universal in diameter and Pitch to give the user a comfortable, easy to use, fast and cost effective solution for any case of defective thread β€”in this we’re the experts! Review: Great tool to get you out of a "jam" - Had a cross threaded bolt on my tractor in an expensive cast section. This tool worked great to clean the threads and save me a ton of money. Review: Never got a chance to use it - The product looks well made and I believe it will do what they say it is supposed to. Unfortunately the sizing is a problem. I had a 3/4" bolt hole that needed to be cleaned out so I ordered this one that is sized for 11/16 to 13/16. They must mean the physical hole size and not the bolt size. This item was way too large to be used with my need. So I ordered the next two sizes smaller and hope one of them works. Whichever works I'll leave a review on that and return the other. When ordering these things remember to order one that will fit the physical dimensions of the bolt hole and not necessarily the size that matches the SAE size of the bolt. ## Features - UNIVERSAL THREAD REPAIR TOOL - one hand tool repairs inch or metric, right or left handed, coarse or fine threads - QUICK SIZING - no need for a caliper or pitch gauge to determine diameter or thread count or type - RAPID ADJUSTMENT - tool adjusts and quickly adapts to particular diameter and pitch of fastener thread - HOW TO USE - automatically chases good threads and the cutter repairs damaged threads - QUALITY CUTTER - blades are made of High Speed Steel induction hardened to 62 Rockwell for longevity of life - SPACE AND TIME SAVINGS - takes the place of hundreds of taps, assorted thread chasers and thread files ## Images ![Universal Internal Thread Repair Tool, 5/16 to 7/16", NES21 - Image 1](https://m.media-amazon.com/images/I/51GL9JEV+SL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great tool to get you out of a "jam" *by R***S on June 13, 2019* Had a cross threaded bolt on my tractor in an expensive cast section.
