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