NAAMS Socket Flat Head Cap Screws

Freer Tool & Supply’s NAAMS socket flat head cap screws collection supports flush, secure fastening for welding fixtures, assembly tooling, and automation builds. Socket flat head cap screws are designed to sit countersunk and nearly flush with the mounting surface—helping reduce snag points and interference in tight-clearance areas where parts slide, locate, or move during a cycle.

NAAMS socket flat head cap screws (F03 series) are made from class 12.9 alloy steel. Available in pitch sizes from M3 to M20 and lengths from 6 mm to 100 mm, these screws meet ANSI B18.3.5M dimensional standards and ASTM F835M material specifications.
