## Questions & Answers

**Q: Why is this labeled as a primerless thread locker? 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

### ⭐⭐⭐⭐⭐ It works!
*by F***W on September 26, 2025*

This stuff is amazing. I used it on a bathroom faucet handle that fell off and it’s perfectly restored.

### ⭐⭐⭐⭐⭐ Red loctite
*by J***. on December 21, 2025*

Does a good job at keeping fasteners tight. You will luckily require some head to disassemble them after it sets up.

### ⭐⭐⭐⭐⭐ For #271 vs. #263, only time will tell, I chose #263
*by E***E on July 24, 2025*

I used this #263 threadlocker to apply to and to hold the four machine threaded panhead fastener screws to affix a metal vertical Mailboss post sleeve over a wood 4" x 4" post to a two mail box spreader by Mailboss. We live in a windy area where typical winds are 12 to 16 mph and gusts reach 40 to 45 mph and higher. The specifications mentioned automobile vibrations, so I equated our nearly constant wind as being directly applicable. The instructions by Loctite are embarrassingly lousy. One source informed me that when using Loctite #263 no primer is required, so I thought I was good to go and this was the correct product for my application, but when my Amazon purchase arrived, the instructions said different. Step #1: "Clean and dry parts with LOCTITE Primer". All of the cost prohibitive, large volume Loctite primers, seemed to include an accelerant which dramatically speeds up the curing time. After doing some research for common ingredients, I soaked the fasteners in acetone, removed them to air dry, and then wiped their threads off with a paper towel before applying the #263 Threadlocker. I used Q-Tips dipped in acetone to clean the internal female threads of the vertical sleeve and then wiped them dry and noticed grey residue on each of the Q-Tips. I had bought #271 Loctite but returned it after reading #263 did not require primer and was better for vibration applications. The preparation and the assembly went smooth enough and time will certainly tell.
