Value Collection MS24693-S6 4-40 Flat Head Phillips Machine Screw

Product Description

The VALUE COLLECTION MS24693-S6 is a 4-40 x 0.5 inch overall length flat head Phillips machine screw manufactured to MS24693 fastener standard. Made from Grade 3 steel with a yellow cadmium finish, this screw is designed for secure, corrosion-resistant fastening in applications where a flush or countersunk head profile is required. The flat head design seats into chamfered or countersunk holes, leaving a smooth surface when fully driven. Yellow cadmium plating provides added protection against corrosion and is commonly specified in aerospace, military, and precision mechanical assemblies.

This screw is suited for use in light-duty mechanical assemblies, electrical panels, enclosures, and instrumentation applications where a 4-40 thread size and flush-mount fastener are specified. The Phillips drive allows installation with standard cross-tip screwdrivers or power drivers. It is commonly used by maintenance technicians, electricians, and mechanical assemblers working on equipment requiring MS-spec hardware.

Key Features

• 4-40 thread size with 0.5 inch overall length
• Flat head profile for flush or countersunk installations
• Phillips drive compatible with standard cross-tip tools
• Grade 3 steel construction for reliable mechanical strength
• Yellow cadmium finish for corrosion resistance
• Manufactured to MS24693 fastener standard

Compatibility

Designed as an OEM-style replacement or specification-grade fastener for assemblies requiring a 4-40 flat head Phillips machine screw meeting the MS24693 standard.

Installation Notes

Install using a Phillips cross-tip screwdriver or power driver sized for a 4-40 fastener. Ensure the mating material has a properly chamfered or countersunk hole to accept the flat head profile fully flush. Do not overtorque, as the small diameter 4-40 thread is susceptible to stripping in softer base materials. Follow applicable assembly specifications or torque tables for 4-40 Grade 3 steel fasteners when defined by the equipment manufacturer.
