Fun Vintage Gold-tone Men's tie clip. A Caliper bolt style threaded adjusting industrial screw with a hexagon top is mounted in an octagon alligator clip tie bar with decorative Greek key designs etched into it.

This is a fabulous fun steam-punk gift for the man in your life who appreciates precision.

A little over an inch in length, eye catching impressive piece.

Why is a screw like this important? I'm glad you asked!

Micrometers measure very small distances, objects, or angles. They use the principle of a screw to amplify small distances (that are too small to measure directly) into large rotations of a screw that are big enough to read on a scale. The
accuracy of a micrometer is driven from the accuracy of the rotation of the finely threaded screw at its heart.

Aww! How sweet, the screw is the heart of the micrometer.
