Value Collection MS24693-C6 4-40 Flat Head Phillips Machine Screw

Product Description

The VALUE COLLECTION MS24693-C6 is a 4-40 unified coarse thread machine screw built to MS24693 military fastener standard. It measures 0.5 inches overall length with a flat head and Phillips drive. The base material is 18-8 stainless steel with a passivated finish, which removes free iron from the surface to improve corrosion resistance. This screw is suited for precision assembly work in aerospace, electronics, military, and industrial applications where a flush seating fastener is required. Machinists, assemblers, and maintenance technicians working to federal or military spec requirements are the typical installers.

This screw is used in applications requiring a countersunk flat head for flush or below-surface installation. The 4-40 thread size is common in electronics enclosures, instrument panels, and light-duty mechanical assemblies. The MS24693 fastener standard makes it applicable in military and aerospace-adjacent manufacturing environments. Minimum order quantity is 100 pieces per package.

Installation Notes

Install using a Phillips screwdriver or bit sized for the No. 4 screw head. Countersink the mating material to the appropriate flat head angle before driving to achieve flush seating. Stainless steel fasteners are susceptible to galling during installation — apply an appropriate anti-seize compound when threading into stainless tapped holes. Torque to the value specified in the applicable assembly drawing or fastener specification document.
