LOCTITE 640 High-Strength Sleeve Retainer, High-Temperature, High-Stength, Anaerobic Adhesive, For Large Diameter Components, Active Metals | Green, 6 ml Tube (PN: 487235)

I used this product for installing my front end meprolight sight of Glock 19 gen4 and it worked really great!!! The sight is well fixed even after shooting 500rds.

When you need metal locking adhesive this is it.

I bought this after reading forum posts about staked vs glued ejectors on 1911s. Apparently this is what the pros use to “glue” ejectors. I had a glued ejector from the factory that came loose after 14 years and didn’t feel like having my ejector staked as it would have made me send my frame back for machine work. This worked perfect to glue my ejector and has held solid for a long time.

Holy smokes, this stuff stopped all my creaky BB30 bottom bracket clicking woes. My original bike assembler didnt use this when installing the bearings, but if you follow Specializeds instructions, they want you to use 640 green sleeve retainer (without saying Loctite). This is it. Use this stuff between your press-fit bearings and the bearing shell.

Quick shipping. Great price. Perfect size for a small to medium project. Used for an internal project on a motor - worked like a champ!

We have a very busy auto repair shop, recently we had a Chevrolet pick up that had lost the differential carrier bearings. When the bearing race spun it damaged the differential housing, because a used one is $500.00 and a new one was out of the question for this customer, we opted to use Loctite #640 high strenth sleeve retainer repair. It did the job very well and we will use it again if we find the need.

Like most loctite products, it worked like advertised, not cheap, but not Cheap..

worked as advertised. used to set a pinion on a shaft. worked very well. sets fairly quickly although I waited 24 hrs. to use.

Good product. Read the applications and usage instructions. It does exactly what it claims to do. If you are using it on a BB30 bottom bracket, be aware that you CAN still remove the bearings later with a sharp rap from a steel hammer.

As advertised
