Flat Carbide / Flat Nylon Dial Indicator Contact Point

These American-made flat contact points have a carbide face on them. They are about the same diameter as most indicator spindles: .185" (7 mm). You'll be able to get them in a variety of lengths but if you need longer lengths, you can get an extension. These carbide points will fit all mechanical and digital dial indicators with inch (4-48) or metric (M2.5) threads. The diameter (ØA) is .185"

We also offer a similar contact point with a nylon surface instead of the carbide. The layer of nylon is about 1.5 mm (± 0.1) in thickness.

  • Recessed carbide surfaces are shown at the bottom of this page.

Flat Point with recessed carbide surface

These flat contact points have a recessed smaller diameter carbide disc brazed onto the surface. They are genuine American-made MTC points designed for Mitutoyo dial indicators and digimatic indicators, but can be used on any indicator having the same thread size.

Examine the dimensions (D/d/L) carefully to make sure you get the correct point.
