NAAMS Clamp Arms - Wishbone

Freer Tool & Supply’s NAAMS wishbone clamp arms collection supports stable, repeatable clamping when you need balanced contact and improved load distribution. Wishbone-style clamp arms are commonly used in welding fixtures, assembly tooling, and automation stations to apply clamping force across two contact points—helping reduce part distortion, improve stability, and maintain consistent location on parts with wider surfaces or complex geometry.

NAAMS wishbone clamp arms feature a double-arm design with bores connected to a single-arm extension. Manufactured from SAE 4140 annealed steel, these arms meet NAAMS Standards and are finished in safety orange. All wishbone models come with an offset of either 25 mm, 50 mm, or 70 mm—measured from the center of the bore to the bottom face of the arm, as shown below. If you need wishbone clamp arms outside of standard NAAMS specifications, please contact us for custom solutions. to contact us at 586-463-3200 or Sales@freertool.com.
