Value Collection MS24693-C4 Flat Head Machine Screw 4-40

Product Description

The VALUE COLLECTION MS24693-C4 is a 4-40 flat head Phillips drive machine screw manufactured to the MS24693 fastener standard. Made from 18-8 stainless steel with a passivated finish, this screw measures 3/8 inches in overall length and is designed for use without a washer. The passivated surface treatment enhances corrosion resistance, making it suitable for demanding environments where stainless fasteners are specified. Licensed electricians, HVAC technicians, and mechanical contractors routinely use machine screws of this type when assembling or servicing panels, brackets, and control enclosures.

This screw is suited for light-duty threaded fastening applications across residential and commercial installations. The 4-40 thread size is common in small electrical enclosures, control boards, terminal strips, and instrumentation hardware. The flat head profile sits flush with the mating surface when countersunk, making it appropriate for assemblies where a raised head would interfere with clearances or panel fit. Sold in a minimum order quantity of 100 pieces per package.

Compatibility

Installation Notes

This screw is installed by hand or with a Phillips head screwdriver sized for a No. 1 or No. 2 bit — confirm the correct bit size before driving to avoid cam-out on the small head. De-energize and lock out any electrical panel or control enclosure before removing or replacing fasteners per standard NFPA 70E lockout-tagout procedures. Do not over-torque; 18-8 stainless fasteners at 4-40 size are susceptible to galling and thread seizure if driven without lubrication into stainless mating threads.
