The MS24693-S278 is a military standard machine screw designed for aerospace fastening applications requiring a flush-mounted installation, secure retention, and dependable service performance. Manufactured in accordance with the MS24693 specification, this fastener is commonly used in aircraft panels, avionics equipment, fairings, access covers, and other aerospace assemblies where precision fastening hardware is required.

Featuring a 100° flat countersunk head with a cross recess (Phillips) drive, the MS24693-S278 is designed to install flush with the surrounding surface when used in a compatible countersunk hole. This configuration helps maintain smooth aircraft contours, reduces interference with adjacent components, and provides consistent clamping force during aircraft assembly and maintenance procedures.

The screw is manufactured from corrosion-resistant aerospace-grade material with a protective finish suitable for aviation environments. Its precision-machined threads provide secure engagement and reliable retention while supporting resistance to vibration, operational stresses, and repeated maintenance cycles.

The MS24693-S278 is an OEM-standard aerospace fastener suitable for aircraft maintenance, repair, and overhaul (MRO) operations where approved replacement hardware is required to maintain proper fit, function, and installation standards.
