ASTM F912M-11

Standard Specification for Alloy Steel Socket Set Screws (Metric) (Withdrawn 2015)

ABSTRACT
This specification covers the requirements and corresponding test methods for quenched and tempered alloy steel socket set screws (SSS) having sizes of M1.6 through M24, hardnesses of 45 to 53 HRC, and belonging to ISO 898/5 property class 45H. These set screws are intended for compression applications only and are not customarily subjected to embrittlement tests. The screws shall be fabricated to a fine grain practice in standard surface finishes, and optional protective coating as specified in the purchase order. Sampled specimens shall undergo heat and product analysis for measurements of the chemical content for carbon, phosphorus, and sulfur. Appropriate tests shall also be performed to analyze the conformance of the screws to mechanical and other property requirements such as torque and torsional strength, microhardness, decarburization, and surface discontinuities.
SCOPE
1.1 This specification covers the requirements for quenched and tempered alloy steel socket set screws (SSS) M1.6 through M24 sizes having hardnesses 45 to 53 HRC, ISO 898/5 property class 45H.
1.2 These set screws are intended for compression applications only and are not customarily subjected to embrittlement tests. For tensile applications, consult with the manufacturer for proper alloy and hardness.
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 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.
Note 1—This specification is the metric companion of Specification F 912.
WITHDRAWN RATIONALE
This specification covered the requirements for quenched and tempered alloy steel socket set screws (SSS) M1.6 through M24 sizes having hardnesses 45 to 53 HRC, ISO 898/5 property class 45H.
Formerly under the jurisdiction of Committee F16 on Fasteners, this specification was withdrawn in December 2015. This standard is being withdrawn without replacement due to its limited use by industry.
