Value Collection R63032844 4-40 Machine Screw Oval Phillips

Product Description

The VALUE COLLECTION R63032844 is a 4-40 UNC machine screw with an oval head and Phillips drive, manufactured from 18-8 stainless steel with a bright, uncoated finish. At 0.25 inches in overall length, this fastener is designed for light-duty mechanical assembly applications where corrosion resistance and a low-profile seating surface are required. The oval head provides a slightly rounded, countersunk appearance that sits flush to slightly above the mating surface. Installers across electrical, HVAC, and general mechanical trades reach for 18-8 stainless hardware when assemblies are exposed to moisture or mild corrosive environments.

This screw is suited for residential and commercial applications involving sheet metal enclosures, control panels, junction boxes, and small mechanical assemblies where a 4-40 threaded hole or nut is present. The Phillips drive is compatible with standard No. 1 Phillips screwdrivers and power drivers set to low torque. The bright uncoated finish keeps the fastener at true dimensional tolerance without adding coating buildup that could affect thread fit in tight clearance tapped holes. This SKU is sold in a package quantity of 1 with a minimum order quantity of 100 units.

Key Features

• 4-40 UNC thread form — standard inch-series coarse thread for broad tool and tap compatibility
• Oval head profile provides a countersunk, low-profile appearance at the fastener seat
• Phillips drive accepts standard No. 1 Phillips hand or power driver bits
• 18-8 stainless steel construction offers corrosion resistance in moisture-prone environments
• Bright uncoated finish maintains true thread dimensions without coating interference
• 0.25 inches overall length suits thin-material and shallow-depth fastening applications

Compatibility

Designed as a standard 4-40 UNC oval head machine screw suitable for any tapped hole, threaded insert, or hex nut conforming to 4-40 UNC thread standards in inch-measurement assemblies.

Installation Notes

Installation requires a No. 1 Phillips screwdriver or a power driver with a No. 1 Phillips bit set to a low torque setting to avoid cam-out or thread stripping in the 4-40 tapped hole. Ensure the receiving hole is properly tapped or that a matching 4-40 nut is used — cross-threading a stainless fastener into a tapped hole can cause galling, which may seize the screw permanently. De-energize any electrical enclosure or panel before installing fasteners inside live equipment per applicable NEC guidelines.
