This pre-assembled high strength, fully threaded, and torque-controlled expansion anchor has a unique safety shoulder in the expansion cone that supports a thick 3-dimple clip engineered to provide high load carrying capability and reduce slip in a variety of installation conditions. Nut and washer included.
ENGINEERED IN THE USA
NOTE: Always wear safety glasses. Follow drill manufacturer's instructions. Use only solid carbide- tipped drill bits meeting ANSI B212.15 diameter standards.
We use these anchors all the time on our tornado safe rooms.
Normally order same product everytime 3/4" x 4 3/4" wedge anchor. The one time I make a mistake because of drop down box I get 8 boxes of 1/4" x 1 1/4" that I have absolutely no use for and no way to return or exchange for what I do use. I love the product I use and we use a lot of them. I will be especially careful when ordering though because if I do something wrong there is no one to talk to to get help.
