Designation:F59284(Reapproved 2012)Standard Terminology ofCollated and Cohered Fasteners and Their ApplicationTools1This standard is issued under the fixed designation F592;the number immediately following the designation indicates the year of originaladoption or,in the case of revision,the year of last revision.Anumber in parentheses indicates the year of last reapproval.Asuperscriptepsilon()indicates an editorial change since the last revision or reapproval.INTRODUCTIONThe 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 theperformance 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 TerminologyF547,Terminology of Nails for Use with Wood and Wood-Base Materials,2for terms that areapplicable 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,registeredtrademarks have become generic in nature;hence,are included among the terms listed.Any such listing cannot be complete.As additional terms are referred to the Societys attention,theywill be considered for inclusion in this standard.This listing of definitions of terms is in agreement so far as feasible with and supplementary toTerminology F547.The definitions are listed under the following headings:Collated and Cohered FastenersTools for Driving Collated and Cohered FastenersCOLLATED AND COHERED FASTENERSbevel pointpoint sheared obliquely to staple-leg axis,withbeveled face across staple-leg end;used to produce anoutward clinch or to provide additional penetration,or both,in thin stapling member(see Fig.1(A).blind clinchclinch between the layers of corrugated boards,usually buried with wide-crown retractable anvil tools.bookbinders wirewire used in stitchers to fasten paper;measured according to AWG sizes.box stay wirewire used in stitchers for assembly of contain-ers;with dimensions measured in thousandths of inches.breakaway staplestaple with its crown designed to break offif removal is attempted;used to discourage pilfering andshop-lifting.by-pass clinchclinch with legs paralleling and adjacent toeach other.calendar staplestaple formed to provide a hanger for usewith calendars or booklets.chisel pointpoint with two symmetrically beveled planesforming“V”at end of staple leg,resulting in straightpenetration(see Fig.1(B).(See cross-cut chisel point.)1These definitions are under the jurisdiction of ASTM Committee F16 onFasteners and are the direct responsibility of Subcommittee F16.05 on Driven andOther Fasteners.Current edition approved April 1,2012.Published May 2012.Originallyapproved in 1978.Last previous edition approved in 2006 as F592 84(2006).DOI:10.1520/F0592-84R12.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 clinchprotruding point end turned over or flattened whendriven or driven against clinching plate.clinch pointpoint designed to facilitate clinching whendriven against clinching plate.(See step point.)clipSee strip.clipped headmisnomer for D head.(See notched head.)coated fastenera fastener with appropriate material appliedto its surface to increase the fastener-withdrawal resistance.coheredassembled in strip,coil,or other predeterminedform as defined in Terminology F547.coiledassembled in coil form.collatedassembled in strip or other predetermined form.cross-cut chisel pointchisel point with beveled point facesparallel to staple-crown axis(see Fig.1(C).(See right-angle chisel point.)crownstaple end opposite staple point,connecting bothstaple legs and providing bearing area.crown widthoverall width of staple including both staplelegs.D headnail head with semi-circular rim and head segmentomitted during heading,with omitted segment reaching fromrim to shank projection,to allow tight collating of nails instrip form.divergent pointSee divergent bevel point.NOTE1Staple chisel point has two faces,forming rectangular cross section;whereas nail chisel point(except collated T-nail chisel point and collatedround-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 eachflank(see ASTM Definitions F547).FIG.1 Various Types of Staple PointsF59
