The MS27039-4-15 is a military standard flush head machine screw designed for aerospace fastening applications where secure attachment, low-profile installation, and reliable service performance are required. Manufactured in accordance with the MS27039 specification, this screw is commonly used in aircraft structural assemblies, access panels, fairings, avionics installations, and other applications requiring dependable aerospace hardware.

Featuring a 100° countersunk flush head, the screw is designed to sit level with the surrounding surface when installed in a properly prepared countersunk hole. This configuration helps maintain smooth aerodynamic surfaces while reducing the possibility of interference with adjacent components or equipment. The precision-machined thread design provides consistent engagement and reliable clamping force during aircraft assembly and maintenance procedures.

Manufactured for aerospace service, the MS27039-4-15 provides excellent mechanical strength and resistance to vibration and operational loads commonly experienced in aircraft environments. Its durable construction supports repeated maintenance cycles and reliable fastening performance when installed according to approved aircraft maintenance practices.

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