The MS24693S4 is a military standard CAD machine screw designed for aerospace fastening applications requiring a secure, flush-mounted installation and dependable mechanical performance. Manufactured in accordance with the MS24693 specification, this fastener is commonly used in aircraft panels, avionics installations, interior assemblies, fairings, and other non-structural aerospace applications where precision hardware is required.

Featuring a 100° flat countersunk head with a cross recess (Phillips) drive, the MS24693S4 is designed to sit flush with the surrounding surface when installed in a compatible countersunk hole. This low-profile configuration helps maintain smooth aircraft surfaces while providing reliable clamping force and easy installation during maintenance procedures.

The screw is manufactured from cadmium-plated carbon steel, providing improved corrosion resistance and durability for aviation environments. With a 4-40 thread size and 3/8-inch length, the MS24693S4 offers precise fit and dependable retention for lightweight aircraft components subjected to vibration and operational stress.

The MS24693S4 is an OEM-standard aerospace fastener suitable for aircraft maintenance, repair, and overhaul (MRO) operations where reliable replacement hardware is required to maintain approved installation standards.
