With a 48-hour full cure time and compatibility across all metal surfaces, it replaces traditional mechanical fasteners, enabling relaxed machining tolerances and delivering industrial-grade reliability. ## Description Brand: Loctite Compatible material: Aluminum Container Type: Bottle Material: threadlocker Review: It dries HARD! - Used to retain the pully side bearing in a Delphi design Aveo alternator which knurls the bearing into the front case. Popping the old Alternator bearing out destroys the knurl, so I am retaining the new 6203 bearing with this Loctite Green. Starts drying in about 15 minutes, and rock hard the next day. This alternator design places all lateral force on this bearing, so is critical not to move. Not an expert, but it looks like the loctite will outlast the new bearing it is retaining. Do notice the volume though - it is a good size container, and provides me enough to rebuild a fleet of Delphi alternators. Review: Putting the LOCK ON TITE ! THE BEST! - This is made to fix a bearing on a shaft to help it became a very tight fit, and works on rifle liners to install in a drilled barrel just give it 24 hours to set properly for any humidity and temperance variance. USE GLOVES AND EYE SHIELDING ! ## Features - High strength, high viscosity room temperature curing adhesive - Used to join fitted Cylindrical parts - Allows relaxed machining tolerances, and replaces Clamp Rings, set screws, and snap Rings - Recommended for retaining shafts, gears, pulleys and similar Cylindrical parts ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00KC541DA | | Best Sellers Rank | #115,977 in Automotive ( See Top 100 in Automotive ) #371 in Automotive Fillers, Adhesives & Sealants | | Brand | LOCTITE | | Brand Name | LOCTITE | | Color | Green | | Colour | Green | | Compatible Material | Aluminum | | Container Type | Bottle | | Customer Reviews | 4.7 out of 5 stars 240 Reviews | | Full Cure Time | 48 Hours | | Global Trade Identification Number | 00079340006843 | | Included Components | Retaining Compounds | | Item Form | Liquid | | Item Package Quantity | 1 | | Item Weight | 82 Grams | | Item form | Liquid | | Manufacturer | Loctite | | Material | threadlocker | | Material Type | threadlocker | | Model | 1835201 | | Other Special Features of the Product | Strong | | Part Number | 1835201 | | Special features | Strong | | Specific Uses For Product | Bearing, Joint, Fan | | Specific uses for product | Bearing, Joint, Fan | | UPC | 079340006843 | | Unit Count | 50.0 Milliliters | | Volume | 1.69 Fluid Ounces | | Water Resistance Level | Not Water Resistant | ## Product Details - **Brand:** LOCTITE - **Item form:** Liquid - **Material:** threadlocker - **Special features:** Strong - **Specific uses for product:** Bearing, Joint, Fan ## Images ![LOCTITE® 680-50ml| green| high strength | cylindrical parts| low viscosity |prevents loosening and leakage from shock and vibration| cures on all metal surfaces| tolerates slightly oiled surfaces - Image 1](https://m.media-amazon.com/images/I/61V9tLMxviL.jpg) ## Questions & Answers **Q: Anyone use this to lock M2 taper chucks/arbors?** A: I've seen it used for that but a clean shrink fit with heated chuck and cooled arbor and tap together with lead hammer does a great job and never slipped for me. **Q: Is there a primer that goes with this for non ferrous metals?** A: I have used this on plastic, Alum and all steels....works well. Never used a primer **Q: Will this provide a strong enough bond between a steel electric motor shaft and a bronze press fit gear?** A: its is pretty stout but i don't know i used it for a shaft that is moved by hand for a small mounted micrometer **Q: Does this foam up?** A: It does not foam. ## Customer Reviews ### ⭐⭐⭐⭐⭐ It dries HARD! *by D***. on 29 November 2020* Used to retain the pully side bearing in a Delphi design Aveo alternator which knurls the bearing into the front case.

THE BEST! *by O***S on 25 August 2025* This is made to fix a bearing on a shaft to help it became a very tight fit, and works on rifle liners to install in a drilled barrel just give it 24 hours to set properly for any humidity and temperance variance. USE GLOVES AND EYE SHIELDING ! ### ⭐⭐⭐⭐⭐ Works for high heat purposes *by B***L on 16 June 2024* A little pricey, but couldn't find it in the store. Was shipped amd received quickly and seemed to work well for a few weeks. My tractor has one cylinder that gets hot and keeps pushing out the valve sleeve. Scored the sleeve and used this to help hold it in place. Worked great until the head cracked then had no choice but to replace it. Was trying to avoid that lol. I will keep around for other projects (hopefully not the tractor again!) ## Frequently Bought Together - Loctite 1835201 Green 680 Retaining Compound, 50 mL Bottle - Loctite 37509 Klean 'N Prime Anaerobic Activator Aerosol Can - 4.5 oz. - 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.hr/products/292024898-loctite-680-50ml-green-high-strength-cylindrical-parts-low-viscosity](https://www.desertcart.hr/products/292024898-loctite-680-50ml-green-high-strength-cylindrical-parts-low-viscosity) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-18*
