Standard Specification for Alloy Steel Socket Button and Flat Countersunk Head Cap Screws (Metric) (Withdrawn 2015) — 5 стр.
Причина отмены 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Formerly under the jurisdiction of Committee F16 on Fasteners, this specification was withdrawn in December 2015. This standard is being withdrawn without replacement due to its limited use by industry.

Реферат

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.
