Designation:F606/F606M14aStandard Test Methods forDetermining the Mechanical Properties of Externally andInternally Threaded Fasteners,Washers,Direct TensionIndicators,and Rivets1This standard is issued under the fixed designation F606/F606M;the number immediately following the designation indicates the yearof original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope*1.1 These test methods cover establishment of proceduresfor conducting tests to determine the mechanical properties ofexternally and internally threaded fasteners,washers,directtension indicators,and rivets.1.2 Property requirements and the applicable tests for theirdetermination are specified in individual product standards.Inthose instances where the testing requirements are unique or atvariance with these standard procedures,the product standardshall specify the controlling testing requirements.In theabsence of any specified test requirement(s),these test methodsshall apply.1.3 These test methods describe mechanical tests for deter-mining the following properties:SectionFor Externally Threaded Fasteners:3Product Hardness3.1Proof Load3.2.1Method 1,Length Measurement3.2.3Method 2,Yield Strength3.2.4Method 3,Uniform Hardness3.2.5Axial Tension Testing of Full-Size Product3.4Wedge Tension Testing of Full-Size Product3.5Tension Testing of Machined Test Specimens3.6Total Extension at Fracture TestSingle Sheer Test3.73.8For Internally Threaded Fasteners:4Product Hardness4.1Proof Load Test4.2Cone Proof Load Test4.3For Washers and Direct Tension Indicators:5Product Hardness-General Requirements5.1Through Hardened Washers5.2Carburized Washers5.3Stainless Steel and Nonferrous Washers5.4Direct Tension Indicators5.5Compression Load5.6For Rivets:6Product Hardness6.1Test for Embrittlement of Metallic-Coated Externally ThreadedFasteners7Test Method for Determining Decarburization and Carburization81.4 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.NOTE1The values are stated in inch-pound for inch fasteners and SImetric units for metric fasteners.1.5 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2A394 Specification for Steel Transmission Tower Bolts,Zinc-Coated and BareE4 Practices for Force Verification of Testing MachinesE8/E8M Test Methods for Tension Testing of Metallic Ma-terialsE10 Test Method for Brinell Hardness of Metallic MaterialsE18 Test Methods for Rockwell Hardness of Metallic Ma-terialsE83 Practice for Verification and Classification of Exten-someter SystemsE92 Test Method for Vickers Hardness of Metallic Materials(Withdrawn 2010)3E384 Test Method for Knoop and Vickers Hardness ofMaterials1These test methods are under the jurisdiction of ASTM Committee F16 onFasteners and are the direct responsibility of Subcommittee F16.01 on TestMethods.Current edition approved Nov.1,2014.Published April 2015.Originallyapproved in 1979.Last previous edition approved in 2014 as F606 14.DOI:10.1520/F0606_F0606M-14A.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.3The last approved version of this historical standard is referenced onwww.astm.org.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 F436 Specification for Hardened Steel WashersF959 Specification for Compressible-Washer-Type DirectTension Indicators for Use with Structural FastenersF1624 Test Method for Measurement of Hydrogen Em-brittlement Threshold in Steel by the Incremental StepLoading TechniqueF2328 Test Method for Determining Decarburization andCarburization in Hardened and Tempered Threaded SteelBolts,Screws,Studs,and NutsF2328M Test Method for Determining Decarburization andCarburization in Hardened and Tempered Threaded SteelBolts,Screws,Studs,and Nuts(Metric)2.2 Military Standard:4MIL STD 1312,Test 13 and Test 203.Test Methods for Externally Threaded Fasteners3.1 Product HardnessTests shall be conducted after theremoval of any surface oxide,decarburization,plating or othercoating.All readings shall be within th
