Loctite Applications

Some of us (read us old timers) don`t remember from day to day what uses each Loctite product has. The following is from some Loctite literature and contains some of their exact wording that I`ve put in quotes.

  • Loctite 242 Nut and Bolt Locker (part #3370) is blue in color and is a medium strength locking compound. This allows fasteners to be disassembled with hand tools yet prevents loosening under normal circumstances`........
  • Loctite 271 Stud Lock (part #3371) is red in color and is a very high strength compound that `is great for problem fasteners that don`t seem to want to stay tight`. `Removal may be difficult and may require heating the fastener`.......
  • Loctite 290 Penetrating Thread Locker (part #3372) is green in color and is a very high strength, low viscosity, compound. It `can be used to lock previously assembled fasteners such as when locking down an adjustment` (their exact words).......
  • Loctite 609 Retaining Compound (part #3373) was developed especially for bonding cylindrical parts such as mounting bearings or bushings into housings as well as mounting pulleys onto shafts, to improve strength of press fit bearings etc.......
  • Locquic Cleaner and Primer (part #3376)is used to clean the surfaces and to speed the cure. Especially important on certain inactive surfaces such as stainless steel......
  • Additionally Loctite makes Pipe Sealant with Teflon (part#3374) and a Gasket Eliminator 515 (part #3375). Hope this helps.....

    Freeing up Locktite

    Came across one of those trick things we all love a few weeks back. Working on a friend`s flathead steering. He`d used red locktite to keep the bolts from loosening and the stuff was really holding. It was in a place where a torch couldn`t be used due to proximity of electrical wiring etc. I had just picked up the cheater bar when another friend dropped by. Saw me with the cheater bar and asked what I was doing. Told him. He said his wife(!) had came through his shop while he was working to free up some locktited bolts and had told him of a super easy way to get the locktite bolts loose WITHOUT the use of heat! Just put a dab of fresh locktite on the bolt and wait about 10 minutes and it`ll loosen all the old set-up locktite! Tried it and the bolts felt like they`d never had any locktite on them! NEAT TIP. Especially for those of us who use green locktite on our Johnson adjustable lifters and we have to reset them.

    RE: Loctite Applications

    Two more goodies from loctite: They make a two-part compound with `weld` in the name that is for fixing or adding material to broken castings. It is fantastically strong and will stick well in real-world settings that are not surgically clean. It`s something to try before you throw out that irreplaceable but cracked part. Another is a thread restorer that allows quick and very strong repairs of stripped fasteners. I`ve used it and think it`s probably a good permanent fix for anything but the most critical fasteners. You have to be quick to use it, though--it hardens a lot faster than the instructions indicate. These would be good items to have when on the road for emergency repairs, and might well afford some permanent solutions. Bruce
