Value Collection MS24693-C1 4-40 Flat Head Phillips Machine Screw

Product Description

The VALUE COLLECTION MS24693-C1 is a 4-40 unified coarse thread machine screw with a flat head and Phillips drive. It measures 3/16 inches in overall length and is manufactured from 18-8 stainless steel with a passivated finish. The passivation process removes surface iron and enhances corrosion resistance without altering dimensions or thread tolerance. At 0.00043 pounds per screw, this fastener is suited for lightweight assemblies where corrosion resistance and precise thread engagement matter. It conforms to the MS24693 fastener standard, making it appropriate for applications that specify military or aerospace-style dimensional compliance. Electricians, HVAC technicians, and industrial maintenance professionals use this size in control panels, instrumentation enclosures, and light-duty equipment assembly.

This screw is used in residential and commercial applications wherever a 4-40 thread pattern and flat head profile are required. The countersunk flat head sits flush with the mating surface, which is important in panel work, electrical enclosures, and instrument mounting where protrusion is not acceptable. The Phillips drive is compatible with standard Phillips screwdrivers and power bits, making installation straightforward in production and field-service environments. Typical applications include light sheet-metal assembly, PCB standoff attachment, and equipment housings requiring stainless hardware.

Key Features

Compatibility

Designed as a direct-fit replacement or standard-stock fastener for any application calling for a 4-40 x 3/16 inches overall length flat head Phillips machine screw meeting the MS24693 dimensional standard.

Installation Notes

Install using a Phillips screwdriver or power driver with a correctly sized bit to avoid cam-out and head damage. Ensure the mating material is tapped to 4-40 thread specification before driving. When installing into stainless tapped holes, apply an appropriate anti-seize compound to reduce the risk of galling. Minimum order quantity for this item is 100 pieces per order.
