ASTM F880-98
(Specification)Standard Specification for Stainless Steel Socket-Set Screws
Standard Specification for Stainless Steel Socket-Set Screws
SCOPE
1.1 This specification covers the requirements for austenitic grade stainless steel socket-set screws (SSS), sizes 0.060 through 0.500 in. in two conditions, AF and CW.
1.2 The following hazards caveat pertains only to Test Method Section, Section 12 of this specification. This standard does not purport to address (all of) the safety problems 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 limitations prior to use.
Note 1—A complete metric companion to Specification F880 has been developed—F880M; therefore, no metric equivalents are shown in this specification.
