Designation:D593396(Reapproved 2013)Standard 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 ensurance 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 for information only.1.3 Safety HazardsThere are no known hazards with theuse of this specification.The products manufactured to thisspecification should not be brittle or difficult to install withproper tools.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Coating(Hot-Dip)onIron and Steel HardwareA570/A570M Specification for Structural Steel,Sheet andStrip,Carbon,Hot-Rolled(Withdrawn 2000)3A653/A653M Specification for Steel Sheet,Zinc-Coated(Galvanized)or Zinc-Iron Alloy-Coated(Galvannealed)by the Hot-Dip ProcessA924/A924M Specification for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.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 performance.All residual metalat casting gate locations and any other protrusions that would1This 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 1,2013.Published April 2013.Originallyapproved in 1997.LAst previous edition approved in 2007 as D5933 96(2007).DOI:10.1520/D5933-96R13.2For 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 States1 prevent the proper installation and fit of the plates shall beground smooth or otherwise removed.5.1.2 Shear plates shall be permanently marked with themanufacturers name or a readily recognizable logo,or both;the number of this ASTM standard;the country of origin;andthe model number,if applicable.Such marking may be on anynonbearing surface and shall be recessed into the device so asnot to interfere with installation or weaken the finished shearplate.5.1.3 Shear plates shall have two diametrically opposedholes which can be used to nail-attach the plate in the piece ofwood in which it is installed to facilitate shippi
