NAAMS Steel Risers
Freer Tool & Supply’s NAAMS steel risers collection supports rigid, repeatable height spacing for welding fixtures, assembly tooling, and automation builds where strength and stability are critical. Steel risers are used to raise locating, clamping, and support components to the correct working height while maintaining a solid foundation—helping reduce deflection, improve alignment retention, and keep part location consistent through high-cycle production
NAAMS steel risers are manufactured from ASTM A-36 steel and are available in a variety of heights. Metric options include M10 x 1.5 tapped holes or 11.0 mm holes, while standard versions feature 3/8-16 tapped holes or 13/32" holes.
