1.1This 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.

1.2Two groups of austenitic stainless steel alloys and three conditions are covered. See Table 1 and Table 2.

(A)Actual full-size testing of condition CW and CW1 may result in decreased tensile strength because of the head configuration (see Table 3). For fasteners with nominal thread diameters larger than 0.625 in., the mechanical properties shall be agreed upon between the user and manufacturer.

(B)Core hardness is only required when full-size product testing cannot be accomplished.

(C)D denotes nominal thread size.

(A)304J3 from JIS G 4309.

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

1.4The 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.
