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.

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 1Pins and wires may be smooth shank or threaded.

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

Note 3On 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 4Optional designs, both ends pointed or point with suture hole.

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

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

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

Note 4Optional marking in this location.

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

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

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
