Abstract:

This specification covers the requirements for quenched and tempered alloy steel screws 0.060 through 1 1/2 inches in diameter having a minimum ultimate tensile strength of 170 KSI. High strength screws shall be heat treated by quenching in oil from above the transformation temperature and then tempered by reheating to at least 797°F to within the hardness range. One or more of the following alloying elements: chromium, nickel, molybdenum, or vanadium shall be present in sufficient quantity to ensure that the specified strength properties are met after oil quenching and tempering. The hardness limits shall be met anywhere on the cross section through the threads, one diameter from the screw point.

Scope:

1.1 This specification covers the requirements for quenched and tempered alloy steel screws 0.060 through 11/2 inches in diameter having a minimum ultimate tensile strength of 170 KSI.

Note 1This specification is the inch companion of Specification F2882M.

1.2 The following hazard caveat pertains only to the test method portion, Section 10, 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.
