This specification covers steel self-drilling and self-piercing tapping screws for the connection of cold-formed steel members manufactured. This specification also covers test methods for determining performance requirements such as dimension, and total case depth; and physical properties such as hardness, ductility, torsional strength, drill drive performance, and self-drilling tapping screw drill capacity.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1.1 This specification covers steel self-drilling and self-piercing tapping screws for the connection of cold-formed steel members manufactured in accordance with Specifications C645 and C955. This specification also covers test methods for determining performance requirements and physical properties.
1.2 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.
1.3 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 and health practices and determine the applicability of regulatory requirements prior to use.
