A mandrel is then drawn back, expanding the tool's threaded area and threading into the clean threads at the bottom of the spark plug hole. The Backtap repairs the damaged thread as it is drawn up through the spark plug hole, bringing debris and metal filings with it. Back-Tap's patented collapsible design allows it to engage be placed through the spark plug hole and into the chamber The Back tap repairs the damaged thread as it is drawn up through the spark plug hole Back-Tap 14 millimeter thread straightening tool for spark plug fouled threads Collapsible design allows it to engage be placed through the spark plug hole and into the chamber Expands the tool's threaded area and threading into the clean threads Review: Very good tool - It help my to rethread spark plug dameged thread on my Toyota prado Review: Quality product. Safely chase out spark plug threads without taking the cylinder head off! - Brilliant design. Life saver when changing old spark plugs that have been in an alloy head for 25 years! (so the cylinder head threads are not in great condition). Perhaps the whole tool could be an inch longer, but I just used a long 1/2 inch socket as an extension. The knurled nut is a bit tricky to tighten up when you're up to your elbows in engine bay. Nevertheless I managed to chase out 4 spark plug holes on an ML430 where the engine bay is very tight on one side. A couple of the plugs were very hard to get out due to binding with the thread in the cylinder head, but after running this tool through them I was able to screw in the new plugs by hand (before torquing up to 25nm). I still have 12 more to do (there are 16 plugs on that engine!) and I'm considering cutting a slot in the end of the knurled nut so I can tighten it with a flat blade screwdriver. Make sure you apply a smear of sticky grease to the thread tap so that it collects any debris as you wind it out of the head. ## Features - SAVES THE DAY: The Back tap repairs the damaged thread as it is drawn up through the spark plug hole bringing any debris with it instead of falling into engine cylinder - PATENTED DESIGN: Collapsible design allows it to engage be placed through the spark plug hole and into the chamber; expands the tool's threaded area and threading into the clean threads drawn up through the plug hole repairing threads as it goes - TIME SAVER: Repairs fouled and damaged threads without removing cylinder heads; no need for tricky thread inserts - TOP QUALITY: Meets or exceeds ANSI standards - STRONG: Made of heat treated 4118 steel - Back-Tap 14 millimeter thread straightening tool for spark plug fouled threads - Collapsible design allows it to engage be placed through the spark plug hole and into the chamber - Expands the tool's threaded area and threading into the clean threads - Backtap repairs the damaged threads as it is drawn up through the spark plug hole ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0014FGVVW | | Brand | Powerbuilt | | Brand Name | Powerbuilt | | Color | Silver | | Colour | Silver | | Country of Publication | China | | Customer Reviews | 4.5 out of 5 stars 1,756 Reviews | | Global Trade Identification Number | 00028907263274 | | Included Components | Back-Tap Thread Repair To | | Included components | Back-Tap Thread Repair To | | Item Dimensions | 12.7 x 1.9 x 25.4 centimeters | | Item Type Name | Back-Tap Thread Repair To | | Item Weight | 0.16 Kilograms | | Item dimensions L x W x H | 12.7 x 1.9 x 25.4 centimeters | | Item weight | 0.16 Kilograms | | Manufacturer | Powerbuilt | | Manufacturer Part Number | 640811 | | Material | 4130 Steel | | Material Type | 4130 Steel | | Model Number | 640811 | | Number of Items | 1 | | Number of Pieces | 1 | | UPC | 740528465287 028907263274 | | Unit Count | 1 Count | ## Product Details - **Brand:** Powerbuilt - **Colour:** Silver - **Item dimensions L x W x H:** 12.7 x 1.9 x 25.4 centimeters - **Item weight:** 0.16 Kilograms - **Material:** 4130 Steel ## Images ![Powerbuilt 14mm Back Tap Thread Repair Tool - 640811 - Image 1](https://m.media-amazon.com/images/I/71yi7la5QvL.jpg) ![Powerbuilt 14mm Back Tap Thread Repair Tool - 640811 - Image 2](https://m.media-amazon.com/images/I/71sHB1LAR0L.jpg) ![Powerbuilt 14mm Back Tap Thread Repair Tool - 640811 - Image 3](https://m.media-amazon.com/images/I/71cJy1fnt9L.jpg) ![Powerbuilt 14mm Back Tap Thread Repair Tool - 640811 - Image 4](https://m.media-amazon.com/images/I/71lf0gC-W5L.jpg) ![Powerbuilt 14mm Back Tap Thread Repair Tool - 640811 - Image 5](https://m.media-amazon.com/images/I/61d2vkTIm9L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very good tool *by A***D on 11 July 2024* It help my to rethread spark plug dameged thread on my Toyota prado ### ⭐⭐⭐⭐⭐ Quality product.
