The Tensilmark is a compact, freestanding unit designed to scribe gauge marks on prepared flat or round specimens made of most machineable materials.  The marks are accurately produced on 1” or 2” centers, within ASTM tolerances of +.002”.  A floating steel bar contains two hardened steel scribe pins for rapid and consistent elongation marks on specimens.

Flat specimens are held in place in the Tensilmark by a positioning bar located in front of the floating steel bar.  The Tensilmark model designed for marking round specimens holds the piece to be marked in a pair of “V” blocks.

For those with custom marking requirements, the Tensilmark can be manufactured with special pins for metric measurements, or for longer samples.
