Concentric OD Clamps

Concentric OD clamps deliver a uniform, centered clamping force around the external diameter of a round workpiece. Designed to enxure concentric location within ±0.0005", these clamps are ideal for secondary machining, finishing, or inspection. The compact form factor simplifies fixture design while enabling 360º access to the part.

Precision Concentricity | Repeatability within ±0.0005" ensures accurate part location
OD Holding Power | Ideal for round parts or turned blanks
Full Top Access | Unobstructed machining on face and ID
Quick Operation | Simple screw-actuated expansion for fast changeovers
Low Fixture Impact | Minimal footprint suits dense or multi-part fixtures

Notes:
12 Mounting Screws included
G – Minimum holding diameter
I – Minimum tap depth
