1. Scope
1.1 This specification covers single-component anaerobic adhesives suitable for locking, sealing, and retaining threaded or
cylindrical assemblies. The adhesives are cured to a solid state when confined between closely fitting active metal surfaces.
1.2 This specification is intended to be a means of classifying anaerobic adhesives. It is not intended for engineering design
purposes.
1.3 This specification is intended to replace Military Specifications MIL-S-22473, MIL-S-46163, and MIL-R-46082.
1.4 The values stated in SI units are to be regarded as the standard.
1.5 The following safety hazards caveat pertains only to the test methods portion, Section 7, 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.

3. Terminology
3.1 Definitions:
3.1.1 Some terms in this specification are defined in Terminology D907.
3.1.2 active metal surface, n—relative to anaerobic adhesives, a metal surface that initiates the formation of free radicals within
anaerobic adhesives.
3.1.3 anaerobic adhesive, n—an adhesive that is kept in the uncured state by oxygen, as in air, and that cures in the absence
of oxygen when exposed to metal ions, especially copper or iron.
3.1.4 Newtonian behavior, n—the property of a liquid in which its viscosity is constant over a stated range of strain rates.
(Compare non-Newtonian behavior.)
3.1.5 non-Newtonian behavior, n—the property of a liquid in which its viscosity is not constant over a stated range of strain
rates. (Compare Newtonian behavior.)
3.1.6 thixotropy, n—in a liquid, the property of thinning when subjected to strains greater than the yield strain and of
rethickening with time upon subsequent rest.

3.1.6.1 Discussion—
The liquid must exhibit yield to be thixotropic. If the liquid is deformed more than the yield strain, the underlying elastic network
is disrupted and its viscosity is reduced. The network reestablishes itself in time when at rest.
3.2 Definitions of Terms Specific to This Standard:
3.2.1 breakaway torque, n—the initial torque required to break the bond, measured at the first movement between the nut and
the bolt, when unscrewing an unseated assembly.
3.2.2 prevailing torque, n—the torque measured at 180° rotation of the nut.
3.2.2.1 Discussion—
Prevailing torque was originally defined in MIL-S-46163 and MIL-S-22473 as the average of the four torques measured at 90, 180,
270, and 360° rotation of the nut. Studies have shown that the torque measured static at 180° rotation of the nut is statistically
D5363 − 16
equivalent to the average of the torque measured at the four ⁄4 turns. Since measuring the torque at the one angle of rotation is
more efficient, prevailing torque is most often defined as the torque measured static at 180° rotation of the nut. However, for
purposes of this specification, the definition of prevailing torque as the average of the four torques measured at 90, 180, 270, and
360° rotation of the nut is also acceptable.
4. Classification
4.1 Anaerobic adhesives are classified into groups in accordance with their performance properties. These groups are subdivided
into classes and grades, as shown in Table 1.
NOTE 1—For example, the designation AN 0411 would indicate:
AN = anaerobic adhesive (from Guide D4800),
04 (Group) = retaining compound,
1 (Class) = low strength, and
1 (Grade) = viscosity of 100–500 mPa.
