Mediumhigh strength thread-locker for general-purpose applications. Especially well-suited for 14 inches to 34 inches 6mm to 20mm fasteners that have slight oil film. Prevents vibration loosening. Oil resistant. Removable with hand tools for easy disassembly. Permatex 24300 Surface Insensitive Threadlocker BLUE Features OEM specified Well-suited for 0.25 inch to 0.75 inch fasteners that have slight oil film Prevents vibration loosening and is oil resistant Suggested Applications Rocker studs, rocker adjustment bolts and bolts on valve and cam covers, oil pans, disc brake calipers, intakes, alternators, and pulley assemblies Review: not problem at all - it came with the package and is working well locking the bolts and screws Review: Perfect application for transmission bolts - I used this Permatex blue thread locker for my 2006 Lexus ES330. After changing the transmission filter, I cleaned the mating surface, added gasket and screwed the pan into the transmission. I added this blue thread locker to each bolt for a total of 18 bolts and tightened up in zig zag pattern. The bottle was enough for all 18 bolts and had some leftover. I believe with this size, it should be enough for two vehicles. It is not only cheaper than Loctile but also provides same strength. It is versatile for other applications as well. It is easy to use and provide great consistency. Until now, the pan has no problems: no oil leaking, no signs of loosening. Great product. ## Features - Secure Every Job – Keep bolts and nuts in place with Permatex Medium Strength Threadlocker Blue, the reliable solution that prevents loosening due to shock and vibration, locking parts securely and shielding threads from corrosion. - Perfect for Automotive & Beyond – With Permatex Threadlocker Blue, seal and lock bolts from 1/4" to 3/4" across various applications, including valve cover, water pump, oil pan, and drive shaft bolts – ideal for any job needing pipe thread sealant. - Perfect For Most Jobs- Permatex Threadlocker Blue Is Ideal For All Nut And Bolt Applications 1/4" To 3/4" (6mm To 20mm) And Eliminates The Need To Stock Expensive Lock Nuts And Lock Washers - Medium Strength for Easy Disassembly – Unlike permanent options, this threadlock holds strong but can be removed with hand tools, allowing easy access for maintenance or adjustments without stripping threads or damaging parts. - Suggested Applications- Valve Cover Bolts, Water Pump Bolts, Oil Pan Bolts, Drive Shaft Bolts, Rocker Arm Adjustment Nuts, Carburetor Studs, Intake Manifold Bolts - All-in-One Solution – Engineered for various applications, this threadlocker provides top-notch thread sealant properties, reducing leaks and corrosion with a tight seal – an essential in any automotive toolkit. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000HBM5TQ | | Brand | Permatex | | Brand Name | Permatex | | Color | red | | Compatible Material | Metal | | Customer Reviews | 4.7 out of 5 stars 1,596 Reviews | | Global Trade Identification Number | 00686226243003 | | Item Dimensions | 19 x 97 x 165 millimeters | | Item Form | Oz | | Item Weight | 27 g | | Item dimensions L x W x H | 19 x 97 x 165 millimeters | | Item weight | 27 g | | Manufacturer | Permatex | | Material | Nylon | | Material Type | Nylon | | Model | 24300 | | Number of Items | 1 | | Part Number | 24300 | | Style | 0.34 oz. | | Style Name | 0.34 oz. | | Supported Standards | Conforms to ASTM D5363 AN0221 (Mil-S- 46163A, Type I, Grade K), D 5363 AN0321 (Mil-S-46163A, II, N) | | Surface Recommendation | Metal | | UPC | 686226243003 | | Water Resistance Level | Not Water Resistant | | Water resistance level | Not Water Resistant | ## Product Details - **Brand:** Permatex - **Item dimensions L x W x H:** 19 x 97 x 165 millimeters - **Item weight:** 27 g - **Material:** Nylon - **Style:** 0.34 oz. ## Images ![Permatex 24300 Surface Insensitive Threadlocker Blue, Thread Lock & Screw Glue for Bolts Nuts & Fasteners to Prevent Loosening & Corrosion, Removable with Hand Tools 10 ml - Image 1](https://m.media-amazon.com/images/I/71V5MMb6ZdL.jpg) ![Permatex 24300 Surface Insensitive Threadlocker Blue, Thread Lock & Screw Glue for Bolts Nuts & Fasteners to Prevent Loosening & Corrosion, Removable with Hand Tools 10 ml - Image 2](https://m.media-amazon.com/images/I/71Uzmi+2BTL.jpg) ## Questions & Answers **Q: What is the exasperation date?** A: Exasperation date is when early on in a relationship, you realize the male is never going to put the toilet seat back down. Then you accept him for the person you love, and not the genetic XY Toilet Seat Disorder he has. So you marry, and then, he also all of a sudden, forgets to flush every. Single. Time. That my friend is an exasperation date. On another not, speaking of this product, and it’s expiration date, you’ll find it crimped on the bottom of tube, I personally haven’t received an expired one yet. My advice? Contact the seller directly, you should be able to click on the seller and pull up at least an email. And ask how far out are the current expiration dates on the products they are shipping out now. If they beat around the bush, look elsewhere because they absolutely should have at the very least an estimated time period. Hope this helps my friend. Because my exasperation has no answer minus purchasing a shock collar for humans. FDA approved ofc, I’m not about torture or etc **Q: What is the best temperature what is to hot for this product** A: temp. ranges are -65 to 300 degrees F. **Q: Can it be used for gun sights?** A: I would NOT use the Permatex MEDIUM STRENGTH Loctite on ANY fastener that is less than 1/4" in Diameter. Doing so can result in STRIPPING out the thread when you attempt to remove the fastener. It is very strong! That would include small set screws as used on weapon scope mounts. For fasteners that are less than 1/4" use Permatex LOW STRENGTH type 222 PINK COLOR. you can find it here on Amazon at a ridiculously low price. You will be able to remove the fastener fairly easily without seizing and stripping the threads. Clean the fastener threads with acetone to remove all oil/grease from the threads and air dry. Apply a small amount to the threads and wipe off the excess with your fingers. The Loctite cures in the absence of air. Make sure you thoroughly wash your hands after using any Loctite product. I hope this helps! **Q: would this work well with a balisong (butterfly knife) screws?** A: It will keep what ever it touches firmly in place. With your application, if the screw has any interaction with the moving parts or the tension of the knife (how easily the knife blade moves) I would urge caution. This blue stuff is not permanent but it will take considerable effort to remove the screw. ## Customer Reviews ### ⭐⭐⭐⭐⭐ not problem at all *by E***L on 1 August 2023* it came with the package and is working well locking the bolts and screws ### ⭐⭐⭐⭐⭐ Perfect application for transmission bolts *by T***Y on 1 May 2026* I used this Permatex blue thread locker for my 2006 Lexus ES330.
