Q-Mark Manufacturing, Inc. designs and manufactures tooling styli for measurement devices, with an emphasis on CMM and machine tooling

Q-Mark began in 1992 by Mark Osterstock, who's customers made him aware of the need for a first-class CMM tooling manufacturer with overnight delivery. Drawing on his earlier career as a tool and die maker, Mark started manufacturing CMM styli on a manually operated lathe, while his wife, Karen, assembled parts on a granite block. Today Q-Mark Manufacturing uses state-of-the-art CNC machinery and proprietary assembly fixtures. Q-Mark offers the following items...

• Various thread sizes: M2, M3, M4, and M5
