Standard Specification for Steel Self-Piercing Tapping Screws for Application of Gypsum Panel Products or Metal Plaster Bases to Wood Studs or Steel Studs

ABSTRACT
This specification covers steel self-piercing tapping screws for use in fastening gypsum panel products and metal plaster bases to cold-formed steel studs and wood members and for fastening gypsum panel products to gypsum board. Steel screws covered by this specification are of four types of thread configurations: (1) Type G, course-pitch high-thread self-piercing screws for fastening gypsum board to gypsum board; (2) Type S, fine-thread screw for fastening gypsum board to cold formed steel members; (3) Type W, course-thread screw for fastening gypsum board to wood members; and (4) Type A, course-pitch tapping screw thread for fastening metal plaster bases to wood or cold-formed steel. All these steel screw types shall be tested for the determination of performance requirements and physical properties (hardness and ductility) covered in this specification. For the appearance of screws, the form shall be straight and neatly formed, and the threads shall be clean and smooth. Screws shall also have a corrosion-resistant treatment which shall not inhibit adhesion to finishing compounds nor bleed through field-applied decoration.
SCOPE
1.1 This specification covers steel self-piercing tapping screws for use in fastening gypsum panel products and metal plaster bases to cold-formed steel studs less than 0.033 in. (0.84 mm) in thickness and wood members, and for fastening gypsum panel products to gypsum board.  
1.2 This specification also covers test methods for determining performance requirements and physical properties.  
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.4 The following safety hazards caveat pertains only to the test methods described in this specification:  
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
