ASTM F 366 : 2024

1.1This specification covers functional dimensions for fixation pins and wires.

1.2In recognition of many broad and varied uses of such pins and wires, many options are included. A variety, but not necessarily all, of the options are illustrated in Figs. 1-3.

FIG. 1Fixation Pins and Wires

Note 1:Pins and wires may be smooth shank or threaded.

Note 2:Point angle and helix angle, where applicable, is as specified by the manufacturer.

Note 3:On square or triangular shanks, flats are equal and corners are on the same circumference as the pin diameter. Shank diameters on pins larger than 3.2 mm may be reduced.

Note 4:Optional designs, both ends pointed or point with suture hole.

FIG. 2Fixation Pin—Knowles Type

Note 1:Shall be made of one piece of material; that is, not an assembly of two or more pieces.

Note 2:Thread major diameter may be the same or larger than the shaft diameter.

Note 3:Thread length shall be optional to suit the intended medical application.

Note 4:Optional marking in this location.

FIG. 3Fixation Pin—Hagie Type

Note 1:Thread major diameter may be the same or larger than the shaft diameter.

Note 2:Thread length shall be optional to suit the intended medical application.

1.3The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.4This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
