MS27039-1-08 – Military Standards Pan Head Aerospace Screw
Available now on the Airparts.aero Marketplace.
Overview
The MS27039-1-08 Pan Head Machine Screw is a military-standard, precision-engineered fastener designed for structural and system applications in both rotary and fixed-wing aircraft. Featuring a Phillips recessed, pan head design, this screw allows for reliable torque control and is ideal for use where a low-profile, surface-mounted fastener is needed in aircraft assemblies.
This screw complies with MS27039 specification, replacing the AN509 family and is made from corrosion-resistant stainless steel, offering strength, longevity, and resistance to vibration-induced loosening. Commonly used in avionics racks, access panels, fairings, and cabin interiors, the MS27039-1-08 ensures uniform load distribution and secure fastening under demanding flight conditions.
