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. Review: Permatex - Great Stuff - I bought this to use when I modify my guns. It works quite well. Buy THIS BRAND, not some knock off brand that will leave you frustrated.

Buy THIS BRAND, not some knock off brand that will leave you frustrated. Don't say I didn't warn you... ### ⭐⭐⭐⭐⭐ Worked for my bicycle's loose crankarm *by J***U on August 25, 2008* EDIT (March 2010): It's still holding tight after 1.5 years! ---- Brief summary: It's been working great for over 3 months on my bike. Longer version: The left crankarm on my 20+ year old bicycle was coming loose every month or so. The local bike shop said that there was nothing I could do short of tightening it and that the problem would get worse until I replaced the crankarm (a >$100 fix and lots of fun trying to locate an overpriced unused vintage part on auction sites). I researched the problem online and came across a few mentions of people using Loctite threadlocker to fix the problem. I decided to get the Loctite 243 since it is resistant to grease. Unfortunately, the local shops only carried Loctite 242 (not oil resistant). Amazon carries Loctite 243, but it is through a third party vendor which charges as much as the item costs for shipping. Fortunately, I came across this Permatex threadlocker, which is also grease resistant (#24300) and is offered with free shipping. My impression is that this is the same exact product as the Loctite 243, but rebranded. Over 3 months ago, I removed my crankarm and wiped the gunk off both the male and female threads. I applied Permatex to the male threads and screwed the crankarm back in. I let it sit undisturbed for 2 days to allow the stuff to fully cure. I have been riding my bike almost everyday since then (about 1000 total miles), but the crankarm has not come loose. I'm so impressed by this product that I decided to use it on other screws that would periodically come loose (like on my rear rack). Everything has stayed in place. If you're unfamiliar with these thread locking compounds, be aware that there are several versions of the Permatex and Loctite. The blue stuff is of medium strength; one should be able to break the seal using the force from hand tools. There's a regular and an oil-resistant version of the blue stuff (best to go with the oil-resistant if you have a choice). If you need something stronger, there's a red version. You'll need to heat that stuff with a blow torch to break the seal. A low strength purple version is also available. ## Frequently Bought Together - Permatex 24027 Surface Insensitive Threadlocker: Threadlocking Adhesive for Medium to High Strength Metal Threaded Assemblies, Easy Disassembly, Vibration Loosening Prevention, Oil Resistant Blue, 6ml - Permatex 81160 High-Temp Red RTV Silicone Gasket: Suitable for Exhaust Manifold, Header, Turbochargers & Slip Fit Exhaust Parts, Temperature Resistant (up to 343Β°C), Sensor Safe, Non-Corrosive 1 x 85g - Lucas Oil 10152 Assembley Lube-118ml --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/26638357-permatex-24027-surface-insensitive-threadlocker-blue-6-ml](https://www.desertcart.in/products/26638357-permatex-24027-surface-insensitive-threadlocker-blue-6-ml) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-08-10*
