Standard Terminology for Anchors and Fasteners in Concrete and Masonry
SCOPE
1.1 This terminology covers standard terminology for anchors and fasteners installed in structural members made of concrete or masonry.
1.2 This terminology does not cover terms relating to the mechanical properties of the materials used for fabricating anchors, nor does it cover their use.
1.3 The terms are listed alphabetically. Compound terms appear in the natural spoken order.
