ASTM F912 - 11(2017)

Standard Specification for Alloy Steel Socket Set Screws

ASTM F912 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. ASTM F912 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.

ASTM F912 Screws

ASTM F912 Screws can be used for many different applications that include fastening wood, steel, and other construction materials for projects such as docks, bridges, highway structures, and buildings. ASTM F912 Set Screws and ASTM F912 Self Drilling Screws is some of the toughest fasteners. These ASTM F912 sturdy fasteners are used to connect heavy materials.

Many of the ASTM F912 Coach screws We produce for more critical high specification Superalloys in our Mumbai Factory. We also manufacture a wide range of the non-favoured thread forms such as BSW BSF UNC & UNF, we are finding the biggest call is now for Socket Head Cap Screws that are modified versions of existing international standards or indeed custom bespoke bolting manufactured to Customer or OEM Drawings.

1. Scope

1.1 ASTM F912 specification covers the requirements for quenched and tempered alloy steel socket-set screws (SSS) in nominal diameters 0.060 through 2 in. having hardnesses 45 to 53 HRC.

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

NOTE 1: A complete metric companion to Specification F912 has been developed—F912M; therefore, no metric equivalents are shown in this Specification.

1.4 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.
