NAAMS Shims - ASH Series
Freer Tool & Supply’s NAAMS shims (ASH Series) collection helps fixture builders fine-tune alignment, height, and stack-up for more repeatable welding, assembly, and automation setups. ASH Series shims are used to make precise adjustments between bases, risers, locators, clamps, and mounting components—helping correct minor variation, improve fit-up, and maintain consistent part location across high-cycle production.
ASH NAAMS shims are metric-fitting and available in thicknesses of 0.25, 0.50, 1.00, and 2.00 mm. Made from S.A.E. 1010 full hard cold rolled strip steel, these shims are offered with yellow zinc dichromate, black oxide, or unfinished surfaces. With Freer Tool & Supply’s ISO 9001:2015 certification, you can count on top-quality NAAMS shims at competitive prices.
The NAAMS full catalog can be found here at the NAAMS Standards website.
