Product Description
The MS51861-25 is a pan head tapping screw conforming to Military Standard MS51861. It features a cross-recess drive and Type A/AB gimlet point designed for forming threads directly into thin sheet metal without pre-tapped holes. Commonly used in aircraft sheet-metal assemblies to attach panels, brackets, and fairings to airframe skins.
Install into a pilot hole and drive per your aircraft maintenance manual to prevent over-torque and thread damage. The gimlet point geometry allows efficient penetration and thread formation in aluminum and composite materials typical of aircraft construction.
