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

This worked really well to secure my dipstick tube into the engine block.

its a great retainer for metal to metal contact. Would recommend and will buy again Thank you very much. RauL

Not something you can find at local home improvement or hardware store. I needed this for an RC helicopter pinion gear gluing to the motor shaft. The torque was enough to break high strength red Loctite 271, but this green 640 stuff hasnt broken yet.

works great to lock bearing race on shafts.

good value

It’s LOCTITE. It’s the Best!

Not much to say, Loctite is great stuff. Do your research before you buy because there are many variants depending on your particular needs. I work at a bicycle shop and we needed this stuff for a repair, nobody in town carried it. Amazon Prime saved the day.
