Freer Tool & Supply’s NAAMS NC Blocks (I-Shape, 3 & 4 Hole) – ANI Series collection supports rigid, repeatable mounting and spacing in welding fixtures, assembly tooling, and automation builds. I-shape NC blocks are commonly used as structural building blocks—helping fixture builders create stable stand-offs, mounting points, and alignment features while keeping layouts consistent and easy to service.
NAAMS NC blocks are blank blocks available in a range of shapes—including I-shape, L-shape, and rectangular—with various 3- or 4-hole configurations, all manufactured in-house. Made from SAE 4140 steel with a black oxide finish or stainless steel (depending on the NAAMS code), these blocks meet all NAAMS standards. We can also produce custom blocks to your specific requirements.
