Freer Tool & Supply’s NAAMS low profile socket head cap screws collection supports secure fastening in tight-clearance fixture and automation builds. Low profile socket head cap screws are designed with a reduced head height compared to standard socket head cap screws—making them a smart choice when you need strong clamping force but have limited space around clamps, locators, risers, or moving components.
NAAMS low-profile socket head cap screws are available in thread sizes from M4 to M20 and lengths ranging from 8 mm to 120 mm. Manufactured from class 10.9 steel, these screws are offered in both unfinished and blue-coated options.
