Freer Tool & Supply’s NAAMS NC Blocks (L-Shape, 3 & 4 Hole) – ANL Series collection supports rigid, repeatable right-angle mounting for welding fixtures, assembly tooling, and automation builds. L-shape NC blocks are used to create stable 90° connections, reinforce fixture structures, and provide consistent mounting points for clamps, locators, and accessory components—helping reduce flex and maintain alignment through high-cycle production.
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.
