> 3 dayUsed this on a lawn mower valve guide that had slipped out. Put this on guide, used punch to tap around it to make it tighter. Have mowed several times and still holding.

10-06-2025I 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.

> 3 dayI have used Loctite for years and mostly very successfully even with heavy industrial use. This sleeve retainer didnt work so well for me on a fairly simple fan to motor shaft sleeve. It wouldnt cure either by warming up both parts and/or attempting to let it setup for more than 24-hours. I was a bit disappointed with this product, I dont know it the clearance was too great for this particular job.

> 3 dayI needed loctite 680 to set some slip fit bearings on my full suspension mountain bike main pivot, but just ended up using this. And I beat the hell out of my bike and not one problem yet...

> 3 dayWe 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.
