Value Collection MS24693-C299 Flat Head Machine Screw

Product Description

The VALUE COLLECTION MS24693-C299 is a flat head Phillips drive machine screw built to the MS24693 fastener standard. It features a 1/4-28 UNF thread and a 1-1/8 inch overall length. The body is machined from 18-8 stainless steel and finished with a passivation treatment to enhance corrosion resistance. This screw is suited for precision assembly work in aerospace, industrial, and mechanical applications where a flush-seating fastener is required. Maintenance technicians, assemblers, and trade professionals install this type of fastener when a countersunk, low-profile head profile is specified by design or code.

This machine screw is appropriate for use in light-gauge metal assemblies, panel mounting, and structural bracketing where 1/4-28 unified fine thread engagement is called out. The passivated 18-8 stainless steel construction makes it a suitable choice in environments with moderate corrosion exposure, including wet or chemically active service conditions. It is sold individually with a minimum order quantity of 100 pieces, making it a standard procurement item for stocking service vehicles, maintenance shops, or production lines.

Key Features

• Flat countersunk head profile seats flush with mating surface for low-profile installations
• Phillips drive for compatibility with standard Phillips drivers and power tools
• 1/4-28 UNF thread provides fine-pitch engagement for secure fastening in metal
• 18-8 stainless steel construction resists corrosion in damp and mildly corrosive environments
• Passivated finish removes free iron from the surface to improve corrosion resistance
• Conforms to MS24693 fastener standard for consistent dimensional and material requirements

Compatibility

Designed as a standard MS24693-series replacement or stock fastener for any assembly requiring a 1/4-28 UNF flat head Phillips machine screw with 1-1/8 inch overall length in 18-8 stainless steel.

Installation Notes

Install using a Phillips screwdriver or power driver sized to fit the head recess; avoid cam-out by using a properly fitted bit. A countersunk pilot hole matched to the screw head angle is required for a flush seat. De-energize or shut down any powered equipment before fastener installation or removal in electrical or mechanical assemblies. Follow applicable industry or OEM torque specifications for the mating material and thread engagement depth.
