A-A-59313, COMMERCIAL ITEM DESCRIPTION: THREAD COMPOUND; ANTISEIZE, ZINC DUST-PETROLATUM (03 FEB 1999) [SUPERSEDING MIL-T-22361]., This commercial item description (CID) covers a zinc dust-petrolatum antiseize thread compound. The thread compound is generally used to prevent seizing during assembly or disassembly of threaded or unthreaded aluminum and aluminum alloy components engaged with components fabricated from similar or dissimilar metals. It also provides corrosion protection to the metal surfaces. The compound is not suitable for use with optical instruments. The thread compound shall be a smooth, homogeneous mixture of zinc dust and petrolatum as specified in table I. The thread compound shall conform to the requirements in table II. Care shall be taken against the application of too heavy a coating of the thread compound to components. A thin coating is all that is required to prevent seizing. In the case of blind holes, the application of an excessive amount of the compound may prevent proper seating of components. Under low temperature conditions, the compound hardens and is difficult to apply. It should be kept at room temperature for 24 to 48 hours prior to use.
