1. Scope

1.1 This specification covers the chemical and mechanical requirements for stainless steel inch hexagon socket button (SBHCS) and flat countersunk (SFHCS) head cap screws with nominal thread 0.060 through 0.625 in. intended for use in applications requiring general corrosion resistance.

1.2 The following three conditions are covered:

1.2.1 Austenitic alloy group 1 AF in an annealed condition at 85 ksi maximum,

1.2.2 Austenitic alloy group 1 CW in a cold-worked condition at 80 ksi minimum, and

1.2.3 Austenitic alloy group 1 condition CW1 in a cold worked condition at 102 ksi minimum.

1.3 Units The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.

1.4 The following precautionary caveat pertains only to the test method portion, Section 12, of 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 limitations prior to use.
