    36 customers mention36 positive0 negative

    Customers like the tightness of the bonding adhesives. They say it holds the small screws securely, and allows them to be removed. It requires a lot of torque and helps screws from becoming loose. It is specific to locking small to tiny screws and fasteners with easy removability. It's the best for keeping them tight without making a permanent connection, and it's good for small screws for snug fit while minimizing the possibility of stripping threads.

    "Not as popular as 243, which will certainly prevent screws from coming undone and make a semi-permanent bond...." Read more

    "This purple loctite difficult to find in local stores. Good for small screws for snug fit while minimizing possibility of stripping threads." Read more

    "This stuff keeps small screws from loosing from vibrations. In my case it's the screws when mounting a scope on a high power rifle." Read more

    Use it on my knife screws
    5 Stars
    Use it on my knife screws
    I recommend this over the blue or red on all your flipper screws. It will hold yet still allow you to break the bond when needed for cleaning etc.
