Made from durable Chrome Molybdenum and meeting ANSI standards, this compact tool is ideal for professional mechanics and DIY enthusiasts aiming to save time and avoid costly cylinder head removals. ## Description The Back-Tap's patented collapsible design allows it to engage be placed through the spark plug hole and into the chamber. 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 Back tap repairs the damaged thread as it is drawn up through the spark plug hole, bringing debris and metal filings with it. Review: Was skeptical but it worked - Restored the thread of a spark plug hole in my Renault cylinder head which had been lightly threaded a few turns. As other reviewers have said, take your time to figure out how the tool works before going in. I passed it through three times as instructed and needed pliers to expand it because of tight access. Review: Take your time and it works - I printed out the 5 star review by HarleyRider, and carefully followed its advice. Result: I sorted out a crossed spark plug thread on my 1972 T series Bentley, without having to remove the affected cylinder head. ## Features - Back-Tap's patented collapsible design allows it to engage be placed through the spark plug hole and into the chamber - Made in USA. Meets or exceeds ANSI standards. - International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0014FGVVW | | Best Sellers Rank | 114,292 in Automotive ( See Top 100 in Automotive ) 186 in Thread Repair Kits | | Brand | Powerbuilt | | Colour | Silver | | Country of Origin | China | | Customer Reviews | 4.5 4.5 out of 5 stars (1,744) | | Global Trade Identification Number | 00028907263274 | | Included Components | Back-Tap Thread Repair To | | Item Dimensions | 12.7 x 1.9 x 25.4 centimetres | | Item Type Name | Back-Tap Thread Repair To | | Item Weight | 0.16 Kilograms | | Manufacturer | Powerbuilt | | Material | Chrome Molybdenum | | Model Number | 640811 | | Number of Pieces | 1 | | Part Number | 640811 | | UPC | 740528465287 028907263274 | | Unit Count | 1.0 count | ## Product Details - **Brand:** Powerbuilt - **Colour:** Silver - **Item dimensions L x W x H:** 12.7 x 1.9 x 25.4 centimetres - **Item weight:** 0.16 Kilograms - **Material:** Chrome Molybdenum ## Images ![Powerbuilt 14mm Back Tap Spark Plug Thread Repair Tool, Straightening Tool, Motorcycle Spark Plugs, Repairs Damaged Threads, Collapsible Design - 640811 - Image 1](https://m.media-amazon.com/images/I/71yi7la5QvL.jpg) ![Powerbuilt 14mm Back Tap Spark Plug Thread Repair Tool, Straightening Tool, Motorcycle Spark Plugs, Repairs Damaged Threads, Collapsible Design - 640811 - Image 2](https://m.media-amazon.com/images/I/71sHB1LAR0L.jpg) ![Powerbuilt 14mm Back Tap Spark Plug Thread Repair Tool, Straightening Tool, Motorcycle Spark Plugs, Repairs Damaged Threads, Collapsible Design - 640811 - Image 3](https://m.media-amazon.com/images/I/71cJy1fnt9L.jpg) ![Powerbuilt 14mm Back Tap Spark Plug Thread Repair Tool, Straightening Tool, Motorcycle Spark Plugs, Repairs Damaged Threads, Collapsible Design - 640811 - Image 4](https://m.media-amazon.com/images/I/71lf0gC-W5L.jpg) ![Powerbuilt 14mm Back Tap Spark Plug Thread Repair Tool, Straightening Tool, Motorcycle Spark Plugs, Repairs Damaged Threads, Collapsible Design - 640811 - Image 5](https://m.media-amazon.com/images/I/61d2vkTIm9L.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Was skeptical but it worked *by T***J on 12 August 2025* Restored the thread of a spark plug hole in my Renault cylinder head which had been lightly threaded a few turns.
