Value Collection MS24693-S1 Machine Screw 4-40 Flat Head

Product Description

The VALUE COLLECTION MS24693-S1 is a 4-40 machine screw built to Fastener Standard MS24693, used across aerospace, military, and general-purpose mechanical assemblies. The screw features a flat head with Phillips drive and is manufactured from steel with a yellow cadmium finish for corrosion resistance. Overall length is 0.1875 inches, with length measured from tip to top of head. Grade 3 material classification applies. This fastener is specified by trade professionals and maintenance technicians working in environments where standardized military-spec hardware is required.

This screw is suited for applications requiring a countersunk flat head profile, allowing the fastener to sit flush with or below the mating surface. It is commonly used in control panels, enclosures, sheet metal assemblies, and equipment frames where a low-profile fastener head is necessary. The 4-40 thread size is a fine unified thread pitch appropriate for thin-gauge materials and precision assemblies. Sold in multiples of 100 units per order.

Installation Notes

Installation is typically performed by mechanical technicians, assembly technicians, or maintenance professionals using a Phillips-head screwdriver or appropriate bit driver. Power down or de-energize any electrical enclosure or equipment before fastener service. Use a countersink or pre-drilled countersunk hole sized for a flat head 4-40 screw to ensure proper flush seating. Do not overtighten into thin-gauge or soft base materials to avoid thread stripping.
