An item designed to be mounted around the extended hub portion of a gear, wheel, or the like, to retain it securely to a shaft by compressing the slotted hub body. The item may also be used to clamp around a shaft, or the like, to prevent end motion or to retain it in position. Its compression quality is derived from a screw(s) or bolt(s) which may be a part of the item of supply. For items designed to secure directly to a shaft by use of setscrews, pins, or the like, see collar, shaft. Excludes clamp, loop.
Packing shall be accomplished in accordance with table c.ii for the packing level specified. closure, sealing and reinforcement shall be in accordance with applicable specification for shipping container.
Packing shall be accomplished in accordance with table c.ii for the packing level specified. closure, sealing and reinforcement shall be in accordance with the appropriate shipping container specification.
Options can be exercised as to specific method of preservation or dod approved packaging materials to be used. however, basic preservation method shall be retained, supplemental data shall be complied with, and unit package dimensions shall not be increased by more than one inch. equal or better protection shall be given the item and there shall be no increase in the package cost.
No special marking.
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.

Indicates there is no data in the hmirs and the nsn is in a fsc not generally suspected of containing hazardous materials.
Item does not contain precious metal.
The item does not have a nuclear hardened feature or any other critical feature such as tolerance, fit restriction or application.
HMIC: Hazardous Material Indicator Code. A one position code that identifies a hazardous item.
PMIC: Precious Metal Indicator Code. A one position code which 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.
