Designation:D593319Standard Specification for258-in.and 4-in.Diameter Metal Shear Plates for Use inWood Constructions1This standard is issued under the fixed designation D5933;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This specification covers standardizing the dimensionsand materials for the manufacture of 258and 4-in.diametersteel or cast iron shear plates used in the fabrication ofconnections in wood constructions.The referencing of thisspecification in design,construction,and purchase order docu-ments gives the using parties assurance that the shear plates tobe used in an assembly meet minimum materials qualitystandards and that dimensions for fabrication and finish can berelied on to ensure connection performance.This specificationprovides regulatory agencies with a set of standards by whichto judge the acceptability of shear plates encountered in thefield and in fabricators shops.1.2 The values stated in inch-pound units are to be regardedas standard.The values in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.3 Safety HazardsThere are no known hazards with theuse of this specification.It is necessary that the productsmanufactured to this specification not be brittle or difficult toinstall with proper tools.1.4 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2A47/A47M Specification for Ferritic Malleable Iron Cast-ingsA153/A153M Specification for Zinc Coating(Hot-Dip)onIron and Steel HardwareA570/A570M Specification for Structural Steel,Sheet andStrip,Carbon,Hot-Rolled(Withdrawn 2000)3A653/A653M Specification for Steel Sheet,Zinc-Coated(Galvanized)or Zinc-Iron Alloy-Coated(Galvannealed)by the Hot-Dip ProcessA924/A924M Specification for General Requirements forSteel Sheet,Metallic-Coated by the Hot-Dip Process2.2 Other Document:AISI/SAE No.1010 Carbon Steel,Steel Products Manual,Plates,Iron and Steel Society3.Terminology3.1 Definitions:3.1.1 shear plateA round,cast,or stamped disk-likeload-transfer device having a flat base and a perimeter bearingrim protruding in one direction normal to the base,with a holepassing through the center of the disk to accommodate anattachment bolt or lag screw.3.1.1.1 DiscussionThe fastener hole at the center mayhave an additional bearing hub.If a bearing hub is present itprojects in the same direction as the bearing rim.A shear plateis installed into one or more faces of a piece of wood to transfershear forces between the member containing the shear plate orplates and adjacent members which may be of wood or steel.This shear transfer is accomplished through the bolt or lagscrew.4.Classification4.1 This specification covers the two basic diameters ofmetal shear plates commonly used in North American timberconstruction258in.(66.7-mm)diameter stamped steel ormalleable cast iron,and 4-in.(102.1-mm)diameter malleablecast iron.The use of these shear plates is covered in theNational Design Specification for Wood Construction4andother wood design documents.1This specification is under the jurisdiction of ASTM Committee D07 on Woodand is the direct responsibility of Subcommittee D07.05 on Wood Assemblies.Current edition approved April 1,2019.Published May 2019.Originallyapproved in 1997.Last previous edition approved in 2013 as D5933 96(2013).DOI:10.1520/D5933-19.2For 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.4Available from the American Forest and Paper Association,1111 19th St.,NW,Suite 800,Washington,DC 20036.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 5.Materials and Manufacture5.1 General:5.1.1 Cast iron shear plates shall be free from any castingdefects such as voids,irregular holes or sharp burrs greaterthan 0.03 in.(0.8 mm),or any other casting defect that wouldhinder normal installation and perfor
