An item of any peripheral shape usually having one flat or spherical surface and a centrally located hole. It is designed for applications involving moving (kinetic) loads. Except for items fabricated from bearing quality synthetic (plastic) or composed of multilayer material, one bearing surface must either have a specific surface finish designation of 32 microinch (0.8 micrometre) or less, arithmetical average (aa) (arithmetic mean deviation) or one of the following conditions: be lapped or ground; have visible or detectable means of lubrication; grooves, indentations; or self-lubrication. The thickness must not exceed 25 percent of the outside diameter of the shortest distance between peripheral flats (when thickness and/or outside diameter is designated as a tolerance dimension, the maximum dimension will be used to determine compliance). Excludes straight, tubular (without flange) items having a bearing surface(s) parallel to the axis of the bore only. See also washer, flat and spacer, sleeve.
Indicates there is no data in the hmirs and the nsn is in a fsc not generally suspected of containing hazardous materials.
Precious metal content is unknown
HMIC: Hazardous Material Indicator Code. Identifies a hazardous item.
PMIC: Precious Metal Indicator Code. Identifies items that have precious metals as part of their content. precious metals are those metals generally considered to be uncommon, highly valuable, and relatively superior in certain properties such as resistance to corrosion and electrical conductivity.
ESD: Electrostatic Discharge. Indicates if an item is susceptible to electrostatic discharge or electromagnetic interference damage. electrostatic discharge damage occurs when an accumulation of static electricity generated by the relative motion or separation of materials is released to another item by direct contact. electromagnetic interference damage occurs when an item comes into proximity with an electrostatic or magnetic field.
ENAC: Enviromental Attribute Code. Identifies items with environmentally preferred characteristics.
CRITL: Criticality Indicator Code. Indicates an item is technically critical by tolerance, fit, application, nuclear hardness properties, or other characteristics.
OPI: Optional Procedure Indicator Code. A one position alpha code that indicates the allowable deviations from the prescribed requirements.
SPI No.: Special packaging instructions number.
LVL A/B/C: Indicates the type of shipping container required for level A, B, or C maximum packing protection.
SPC Mkg: A two position code that identifies the special markings applied to the container, which is part of the total pack to protect the contained item during preservation, packing, storage, transit and removal from the pack.
MOP: Method of Preservation. Preventive measures to protect from deterioration resulting from exposure to atmospheric conditions during storage and shipment.
CUSH: Resilient material or devices used to absorb and dissipate energy from shock and vibration to adequately protect the contents and packaging components from physical damage during handling, shipment, and storage.
PRES MAT: Preservation Material. Identifies the material used to prevent or inhibit corrosion or deterioration of an item.
THK: Thickness of cushioning. Minimum thickness of material used to cushion the item.
TOS: Type of Storage. Type of storage space and environment conditions to be maintained for an item during storage and shipment.

LTL: Less than a truckload rating.
LCL: Less than a carload rating.
WCC: Water commodity code. A three position code that indicates all shipments via water.
TCC: Type of Cargo Code. A one position code for all shipments via water to identify the type of cargo included within the shipment unit.
SHC: Special Handling Code. A one position code for all shipments via water to identify the exception handling required for cargo included within the shipment unit
ADC: Air Dimension Code. A one position alpha code that identifies dimensional characteristics of air shipments by relating the length, width, or height dimensions of the largest piece to the minimum size cargo door opening of an aircraft
ACC: Air Commodity Code. A one position code for all shipments via air to identify material for manifesting and customs requirements
