Literally the first step on the package instructions is to prep your surface with a primer.** A: Loctite 263 is actually primerless on most metals. This is an automotive aftermarket package, and there is a Klean 'n' Primer product sold that is usually suggested for all anaerobic products. You can just clean the parts with alcohol or acetone. No primer is required. If you need further assistance, please contact the LOCTITE Technical team at 1-800-LOCTITE **Q: Does Loctite 263 have a limited shelf life?** A: Yes, Loctite 263 threadlocker has a limited shelf life of 730 days from the date of manufacture. This means that it is important to check the expiration date on the product before using it. If the product is expired, it may not perform as expected. **Q: Approximately how many 1/4" studs can be set with the 6m tube?** A: For small threads, we typically recommend applying 1 big drop (or 2 drops small/medium drop max) to the male threads at the engaging area, vs the female thread in the hole in a blind. The idea is to ensure a good coverage in the engaging/mating area of the nut and bolt. For 1/4" bolt, I estimate 200 bolts with a 6ml tube, of a manual application from the bottle. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product *by T***L on 23 June 2026* Great product. Always works. ### ⭐⭐⭐⭐⭐ Cumple con sus especificaciones. Loctite es una garantía. *by M***U on 18 September 2025* La marca es una garantía. Lo recomiendo. ### ⭐⭐⭐⭐⭐ Good old red threadlock *by T***G on 13 July 2024* Purchased this after doing some research into red threadlock. Back in the days (of 1995 it would seem), cars (maybe just mine) called for red threadlock. In the service manual of my 1995 E34 BMW they didnt call for a 263 loctite threadlocker but instead just called for red threadlock. Now with some considerable digging and references across forums and Loctites own data, I was able to determine that 263 is the closest modern version. 263 is also indeed red. So if you're here for that, then I hope my review acts as a confirmation. With that said, the threadlocker performs as it should. The suspension/drivetrain component that I used this on (following the factory service manual) had yet to come undone and fail. And it had been roughly 10k km after the repair so I would say it's held up well. I've yet to need this in any other applications at the moment but if it's been trusted on a crucial component of a close to 30 year old car and then performed according after use then I'd say it's trusted in my books. So definitely recommend 263 for all 263-related and red loctite-related applications. ## Frequently Bought Together - LOCTITE 263 Automotive Threadlocker Red – High Strength Thread Lock, General Purpose Applications, Oil Tolerant, Fluorescent - 6 ml, 1 Pack - Loctite Threadlocker Blue 242 - Removable Thread Lock Glue for Nuts, Bolts, & Fasteners, Medium Strength Screw Glue to Prevent Loosening & Corrosion - 6 ml, 1 Pack - Loctite 1329467 243 Blue Medium Strength Threadlockers, 1.69 Ounces, 50 mL, 3/4" Thread --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/299024249-loctite-2203451-threadlocker-263-surface-insensitive-high-strength-tube-red](https://www.desertcart.sg/products/299024249-loctite-2203451-threadlocker-263-surface-insensitive-high-strength-tube-red) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-07-07*
