The MS24693-S28 is a military standard countersunk head machine screw designed for aerospace fastening applications requiring a flush installation, secure mechanical retention, and reliable 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 hardware is required.

Featuring a 100° flat countersunk head with a cross recess (Phillips) drive, the MS24693-S28 is designed to sit flush with the mating surface when installed in a compatible countersunk hole. This low-profile design helps maintain smooth aircraft contours, minimizes interference with adjacent components, and provides consistent clamping force during assembly and maintenance procedures.

Manufactured from carbon steel with a cadmium and chromate protective finish, the screw provides improved corrosion resistance and durability for demanding aerospace environments. Its precision-machined threads ensure secure engagement and dependable fastening performance under vibration, operational loading, and repeated maintenance cycles.

The MS24693-S28 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.
