Freer Tool & Supply’s NAAMS socket set screws collection supports secure positioning and retention in welding fixtures, assembly tooling, and automation builds. Socket set screws (often called grub screws) are designed to lock components in place without a protruding head—making them a strong choice for collars, stops, locators, and adjustable elements where you need holding power in tight-clearance areas.
NAAMS socket set screws are manufactured from class 45H steel and meet ANSI B18.3.6 dimensional specifications. Hex socket sizes range from 2.5 to 12, with nominal screw lengths from 3 mm to 30 mm. Available in three styles: F21 series (flat point), F22 series (cone point), and F23 series (cup point).
