Value Collection MS24693-C293 Machine Screw 1/4-28

Product Description

The VALUE COLLECTION MS24693-C293 is a flat head Phillips drive machine screw engineered to the MS24693 military and aerospace fastener standard. It features a 1/4-28 UNF thread form and a 7/16-inch overall length, making it a compact fastener suited to close-tolerance assemblies where a flush or countersunk finish is required. The base material is 18-8 stainless steel with a passivated finish that enhances corrosion resistance without adding dimensional build-up. This screw is specified and installed by maintenance technicians, mechanical assemblers, and field service professionals across industrial, HVAC panel, and equipment enclosure applications.

This fastener is appropriate for metal panel assemblies, equipment housings, junction boxes, and structural sub-assemblies that call for a countersunk or flush seating surface. The fine 1/4-28 thread pitch provides strong clamping force and vibration resistance in thin-wall or close-tolerance tapped holes. It is sold individually with a minimum order quantity of 100 pieces per order, making it suitable for shop stock, service van kits, or production line use where consistent fastener specification is required.

Key Features

• 1/4-28 UNF fine thread for high clamping force and vibration resistance in tapped assemblies
• Flat head profile seats flush or countersunk into mating material for a smooth finished surface
• Phillips drive compatible with standard hand and power drive tooling
• 18-8 stainless steel construction with passivated finish for corrosion resistance in demanding environments
• Meets MS24693 fastener standard for dimensional and material consistency
• 7/16-inch overall length suits thin panel and enclosure fastening applications

Compatibility

Designed as an OEM-style replacement or service fastener for assemblies specifying MS24693 series flat head Phillips machine screws in 1/4-28 UNF thread size.

Installation Notes

Installation is performed by hand or power driver using a Phillips bit sized for a 1/4-inch fastener. Ensure the mating hole is properly tapped or threaded to 1/4-28 UNF specification before driving. De-energize and lock out any electrical or mechanical equipment before accessing fastened panels or enclosures. Avoid over-torquing stainless steel fasteners, as 18-8 alloy is susceptible to galling in stainless-to-stainless assemblies; apply an appropriate anti-seize compound where required by the job specification.
