Freer Tool & Supply’s NAAMS hex head screws collection supports strong, reliable fastening for welding fixtures, assembly tooling, and automation builds. Hex head screws are a common choice for securing bases, risers, brackets, and mounting components—helping maintain clamp load and alignment in production environments where fixtures see repeated cycles and vibration.
NAAMS hex head screws are manufactured to ANSI B18.2.3.1M dimensional standards and ASTM F568M, class 10.9 material specifications. Available sizes range from M5-0.8 x 6 up to M36-4.0 x 200, with options in both blue-coated and uncoated finishes.
