The MS27039-4-13 is a military standard flush head machine screw designed for aerospace fastening applications requiring secure attachment, precision fit, and a low-profile installation. Manufactured in accordance with the MS27039 specification, this screw is widely used in aircraft assemblies including structural panels, fairings, access covers, avionics installations, and other areas where dependable fastening performance is required.

The screw features a 100° flush countersunk head that allows it to sit smoothly with the surrounding surface when installed in a properly prepared countersunk hole. This design helps maintain aerodynamic surfaces, reduces protrusion, and minimizes interference with nearby aircraft components. The precision-formed threads provide reliable engagement and consistent clamping force during assembly and maintenance operations.

Manufactured for demanding aerospace environments, the MS27039-4-13 provides excellent durability and resistance to vibration, operational stress, and repeated maintenance cycles. Its standardized design allows qualified technicians to replace existing hardware while maintaining the original installation requirements of the aircraft assembly.

This product is supplied in a 10-piece pack, making it suitable for aircraft maintenance, repair, and overhaul (MRO) operations requiring controlled quantities of OEM-standard fasteners.
