Put it on the threads of the screw and wait the full 24 hours to be sure it's set. Been using their stuff for many years. Make sure you get the right strength for the size of your screws. - Low strength (this item) - purple/loctite 222 (liquid) is for up to 1/4" screws Med strength - blue/loctite 243 (liquid) & 248 (stick) is for 1/4" to 3/4" screws High strength - red/loctite 263 (liquid) is for up to 1" screws Purple you can take the screw back out with just a hand tool. Blue you may need some sort of leverage. Red you'll want to heat up a little bit before trying to remove the screw. Stay within the manufacturer's suggested strength for your screw size to avoid risking stripping/damage. I've stripped a few screws in the past thinking that it would be fine, but the screws were softer than I expected. Not worth the risk/headache. Using one too weak and you'll risk it not holding well enough. Review: Seems to be good - Have only used to secure 1 optic at this time. So far, so good. ## Features - Ideal for fastener diameters of 1/4" and smaller - Controlled lubricity for accurate clamp loads - Item Package Dimension: 3.5" L x 1.0" W x 0.9" H - Item Package Weight: 1.0 lb ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B006GOL5CQ | | Best Sellers Rank | #354,403 in Automotive ( See Top 100 in Automotive ) #137 in Thread Lock Sealers #6,153 in Oils & Fluids | | Brand | Loctite | | Brand Name | Loctite | | Color | Purple | | Compatible Material | Plastic | | Container Type | Bottle | | Customer Reviews | 4.8 out of 5 stars 917 Reviews | | Full Cure Time | 24 hours | | Global Trade Identification Number | 00079340222212 | | Included Components | Instruction guide included | | Item Form | Liquid | | Item Package Quantity | 1 | | Item Weight | 18.14 g | | Manufacturer | Loctite | | Material | Plastic | | Material Type | Plastic | | Model | 22221 | | Number of Pieces | 1 | | Other Special Features of the Product | low strength | | Part Number | 22221 | | Special Feature | low strength | | Specific Uses For Product | Repair | | UPC | 079340222212 640024983806 | | Viscosity Level | Low to Medium | | Volume | 10 ml | | Water Resistance Level | Water Resistant | ## Product Details - **Brand:** Loctite - **Item Form:** Liquid - **Material:** Plastic - **Special Feature:** low strength - **Specific Uses For Product:** Repair ## Images ![Loctite 22221 Threadlocker 222MS, Purple, 10mL Volume - Image 1](https://m.media-amazon.com/images/I/717M776Bm1L.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: Can this be used for screws on watch bracelets etc.? Thank you.** A: Yes, any fastener under 1/4". Blue lecture will work as well, but I prefer purple if the screw will need to come out in the future. If you don't ever plan on removing the screw, use red. I use purple on light duty fasteners such as RC airplanes/helicopters, small firearm components, etc. **Q: Can this be used to lock nylon set screws in an 6061 aluminum bar?** A: I haven't used it in this application. I use it as a very low tension threadlocker on tiny screws..Have you tried Loctite blue threadlocker? Can you change out the nylon setscrews for brass or stainless steel ones? Those would be very lockable with any of the loctite products. The nylon is the problem since it distorts easily. **Q: Does this Come with the Mil Spec certifications?** A: Only the bottle of Loctite is received. I would suspect that the certs can be downloaded from the Loctite web site. **Q: Is this the one recomended by Rolex for the bracelet screws?** A: Yes, Rolex uses Loctite 222 for this purpose. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good stuff! *by C***. on April 21, 2018* Good for keeping screws in and nuts on bolts.

So far, so good. ### ⭐⭐⭐⭐⭐ Low Strength Threadlocker *by K***3 on March 5, 2018* Loctite is a well known solution to keep screws from coming loose. There are different strengths (and other variants) to provide the right variety for the application needs. This purple variety is a low strength threadlock. Works well for something you may want to unscrew again without worrying about stripping the head, especially head types that cam out more easily. Yet it secure enough to give you confidence that they won't come loose from light use (carry / vibration). Easy to apply, easy to cleanup. ## Frequently Bought Together - Loctite 22221 Threadlocker 222MS, Purple, 10mL Volume - Loctite 1329467 243 Blue Medium Strength Threadlockers, 1.69 Ounces, 50 mL, 3/4" Thread - Loctite Threadlocker 242, 50mL Bottle, Blue --- ## 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.ie/products/11460277-loctite-22221-threadlocker-222ms-purple-10ml-volume](https://www.desertcart.ie/products/11460277-loctite-22221-threadlocker-222ms-purple-10ml-volume) --- *Product available on Desertcart Ireland* *Store origin: IE* *Last updated: 2026-08-12*
