These micrometers reach over the edge of sheet metal and take measurements away from the edge toward the center. Also for other gaging jobs where a deep throat micrometer is needed. Rounded anvil on 1" (25 mm) size gives a point contact for more accurate gaging; flat anvil is also available. The 1/2" and 13 mm micrometers have satin chrome frames; 1" and 25 mm micrometer frames have black wrinkle finish.
