Rule 49.3-B
49.3-B. Size
1) Wood Pins: The minimum diameter of the shank shall not be less than 1 ¼ inches.
2) Metal Pins: The minimum diameter of the shank shall not be less than ½ inches.
3) Fastenings and Tie Wires: Fastenings and tie wires shall have no sharp edges at points of contact with conductors, and shall be applied in such a manner as not to damage the conductor. The materials and minimum sizes of tie wires for the various sizes and types of conductors shall be as shown in Table 7. Flat tie wire having a cross-sectional area not less than that of round wire of the gage specified for tie wires may be used.
