Starrett Contact Point Sets for Plunger-Style Variance Indicators
These contact points are compatible with indicators that conform to AGD standards. Most plunger-style indicators are classified in AGD Groups 0, 1, 2, 3, or 4.
Radius and button contact points are best for use on flat surfaces.
Ball contact points are for measuring indentations. They can also be used to measure flat surfaces.
Bell contact points are used for measuring convex surfaces.
Tapered contact point can probe the bottom of a groove or narrow hole.
Cone contact points allow for precise positioning of the measuring tip. They are not for use on soft materials.
Shock-absorbing contact point protects against mechanical shock. A sudden impact will cause the tip to retract into the contact point’s body.
