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. ## 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.jp/products/319115162-263-threadlocker-for-automotive-high-strength-oil-tolerant-high-temp](https://www.desertcart.jp/products/319115162-263-threadlocker-for-automotive-high-strength-oil-tolerant-high-temp) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-09*
