Value Collection MS24693-C300 Machine Screw 1/4-28

Product Description

The VALUE COLLECTION MS24693-C300 is a 1/4-28 unified fine thread machine screw with a flat head and Phillips drive. Built to the MS24693 fastener standard, it is manufactured from 18-8 stainless steel with a passivated finish that enhances corrosion resistance. The overall length is 1-1/4 inches, measured from tip to the top of the flat head. This screw is suited for use in mechanical assemblies, electrical enclosures, HVAC equipment panels, and general industrial applications where a flush-mount fastener and corrosion resistance are required. Installation is performed by mechanics, electricians, and HVAC technicians working on metal panel or sheet metal assemblies.

This screw is commonly used in light industrial and commercial equipment assemblies requiring a fine-thread, flush-seating fastener. The flat head countersinks flush with the mating surface, making it appropriate for panels, brackets, and enclosures where a protruding fastener head is not acceptable. The 1/4-28 thread pitch provides stronger thread engagement per inch compared to coarse-thread variants, which is an advantage in thinner materials and vibration-prone environments.

Key Features

• 1/4-28 unified fine thread for high thread engagement in thin materials
• Flat head profile seats flush with mating surface for clean panel installations
• Phillips drive compatible with standard power and hand tools
• 18-8 stainless steel construction for corrosion resistance
• Passivated finish further improves oxidation resistance
• Manufactured to MS24693 fastener standard for dimensional consistency

Compatibility

Designed as an OEM-style replacement or maintenance fastener for equipment assemblies specifying a 1/4-28 flat head Phillips machine screw per the MS24693 fastener standard.

Installation Notes

Install using a Phillips screwdriver or appropriate power driver bit rated for the fastener size. For flush seating, ensure the receiving material is properly countersunk to match the flat head angle before driving. Torque to the specification called out in the equipment service documentation. Stainless steel fasteners are susceptible to galling — apply an appropriate anti-seize compound when threading into stainless steel mating hardware.
