ASTM F835M-11

Standard Specification for Alloy Steel Socket Button and Flat Countersunk Head Cap Screws (Metric) (Withdrawn 2015)

ABSTRACT
This specification covers the requirements for quenched and tempered alloy steel hexagon socket button (SBHCS) and flat countersunk (SFHCS) head cap screws. The screws shall be fabricated from alloy steel made to fine grain practice. The chemical composition of the screw material shall conform to the heat analysis specified. Hardness, tensile strength, yield strength, elongation, and area reduction shall be tested to meet the requirements prescribed.
SCOPE
1.1 This specification covers the requirements for quenched and tempered alloy steel hexagon socket button (SBHCS) and flat countersunk (SFHCS) head cap screws M3 through M20 thread sizes having material properties of ISO 898/1 Property Class 12.9.  
1.2 Fasteners meeting this specification are intended for shear type applications and have tensile requirements equivalent to ISO 898/1 Property Class 10.9.
1.3 The hazard statement pertains only to the test method section, Section 11 of this specification. This standard does not purport to address all of the safety problems, 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.
WITHDRAWN RATIONALE
This specification covered the requirements for quenched and tempered alloy steel hexagon socket button (SBHCS) and flat countersunk (SFHCS) head cap screws M3 through M20 thread sizes having material properties of ISO 898/1 Property Class 12.9.
Formerly under the jurisdiction of Committee F16 on Fasteners, this specification was withdrawn in December 2015. This standard is being withdrawn without replacement due to its limited use by industry.
