Imperial Vernier Micrometer

Accurate to 0.0001", this 0 to 1" micrometer is just about at the practical limit of hand measurement.

Graduated in 0.025" increments on the barrel, 0.005" increments on the knob, and 0.0001" increments on the vernier scale. A lever lock lets you fix a given measure, and a fixed tension ratchet adjustment knob ensures standard force when measuring deformable material.

A fine tool at an excellent price. Comes in a protective case (wrapped in 0.0024" thick plastic!). Overall length is 5 1/4".
