NAAMS Shims

NAAMS shims NAAMS shims are used to close small gaps in automation setups, fitting between blocks, arms, and other spacers as needed. They’re available in 0.25 mm, 0.50 mm, 1.00 mm, and 2.00 mm thicknesses and are made from S.A.E. 1010 full hard steel. Finish options vary by size: 0.25 mm and 2.00 mm shims are uncoated, 0.50 mm shims are yellow zinc dichromate coated, and 1.00 mm shims have a black oxide finish. These shims help fine-tune alignment and add support for a more secure fit—custom shims are also available upon request. Call us at 586-463-3200 for a quote.
