Standard Specification for Fixation Pins and Wires

ABSTRACT
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.
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.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
Note 1—Pins and wires may be smooth shank or threaded.
Note 2—Point angle and helix angle, where applicable, is as specified by 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 1/8 in. (3.2 mm) may be reduced.
Note 4—Optional designs, both ends pointed or point with suture hole. FIG. 1 Fixation Pins and Wires
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 intended medical application.
Note 4—Optional marking in this location. FIG. 2 Fixation Pin-Knowles 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 intended medical application. FIG. 3 Fixation Pin-Hagie Type
