INTRODUCTION
The terms included in these definitions are listed in alphabetical order to facilitate quick reference.
They are intended to apply to collated and cohered nails, staples, and pins driven by strike, pneumatic,
electric, manual, and spring tools. Omitted from consideration are terms relating to the testing and the
performance of fasteners, that is, their drivability, withdrawal resistance, pull-through resistance,
lateral load transmission, creep, protrusion resistance, splitting, and methods of use, such as face, toe,
side, and end-nailing, spacing, loading conditions, etc. Reference is made to ASTM Terminology
F547, Terminology of Nails for Use with Wood and Wood-Base Materials, for terms that are
applicable to related fasteners that may or may not be collated or cohered.
Common acceptance and usage are the basis for most of the definitions listed. In some instances,
this common usage results in more than one definition for a given term. In other cases, registered
trademarks have become generic in nature; hence, are included among the terms listed.
Anysuchlistingcannotbecomplete.AsadditionaltermsarereferredtotheSociety’sattention,they
will be considered for inclusion in this standard.
This listing of definitions of terms is in agreement so far as feasible with and supplementary to
Terminology F547.
The definitions are listed under the following headings:

NOTE—Staple chisel point has two faces, forming rectangular cross section; whereas nail chisel point (except collated T-nail chisel point and collated
round-head nail chisel point) has six faces, forming hexagonal cross section, that is, two major planes forming a “V” and pair of minor planes on each
flank (see ASTM Definitions F547).
