    This specification covers the material requirements and functional dimensions for fixation pins and wires. Factors such as bending strength, fatigue strength, break strength (Knowles type only), torsion strength, and ductility are considered important but the values and associated test methods for which have not been established yet.

    This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

    1. Scope

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

    1.2 In 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. 1 Fixation Pins and Wires

    Fixation Pins and WiresFixation 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. 2 Fixation Pin-Knowles Type

    Fixation Pin-Knowles TypeFixation 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. 3 Fixation Pin-Hagie Type

    Fixation Pin-Hagie TypeFixation 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.

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

    1.4 This 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.
