NAAMS Clamp Arms - Offset
Freer Tool & Supply’s NAAMS offset clamp arms collection supports reliable, repeatable clamping when your fixture layout needs added reach, clearance, or a shifted contact point. Offset clamp arms are used with power clamps in welding fixtures, assembly tooling, and automation stations to route clamping force around obstructions, clear locators, or clamp parts with complex geometry—helping maintain consistent hold-down without redesigning the entire station.
NAAMS offset power clamp arms are manufactured from 4140 annealed steel and finished in safety orange, fully meeting NAAMS Standards. Available offsets include 20 mm, 25 mm, 45 mm, 65 mm, 70 mm, 115 mm, and 120 mm—measured from the center bore to the bottom face of the arm, as shown in the image below. These arms are offered as blanks or with alternating hole patterns ranging from 4 to 14 holes. We supply both current and discontinued models and can manufacture custom clamp arms to your specifications. To view the complete catalog, click the link below.
