1.1 This specification covers standardizing the dimensions and materials for the manufacture of 25⁄8 and 4-in. diameter steel or cast iron shear plates used in the fabrication of connections in wood constructions. The referencing of this specification in design, construction, and purchase order documents gives the using parties ensurance that the shear plates to be used in an assembly meet minimum materials quality standards and that dimensions for fabrication and finish can be relied on to ensure connection performance. This specification provides regulatory agencies with a set of standards by which to judge the acceptability of shear plates encountered in the field and in fabricators’ shops. 1.2 The values stated in inch-pound units are to be regarded as standard. The values in parentheses are for information only. 1.3 Safety Hazards—There are no known hazards with the use of this specification. The products manufactured to this specification should not be brittle or difficult to install with proper tools.
