Value Collection R63032842 Machine Screw 4-40 Oval Phillips

Product Description

The VALUE COLLECTION R63032842 is a 4-40 UNC machine screw designed for precision fastening in light-duty mechanical assemblies. It features an oval head profile with a Phillips drive and is manufactured from 18-8 stainless steel with a bright, uncoated finish. The overall length is 0.375 inches, measured from end to end, with a length under the head also measuring 0.375 inches. This screw is suited for applications requiring corrosion resistance and a flush-to-countersunk aesthetic. It is sold in a package quantity of 1 with a minimum order quantity of 100 units, making it appropriate for production or service shop procurement.

This screw is used in applications where a countersunk or slightly raised head profile is preferred over a flat or pan head. Common install scenarios include enclosure panel fastening, electronics chassis assembly, instrument mounting, and light mechanical hardware work. The 4-40 thread size is standard in precision instrument and electronics assembly. The 18-8 stainless steel construction makes it appropriate for environments with moderate moisture exposure or where corrosion resistance is a requirement.

Key Features

• 4-40 UNC thread form for compatibility with standard 4-40 tapped holes and hex nuts
• Oval head profile provides a low-profile countersunk appearance with a slightly domed top
• Phillips drive for use with standard Phillips screwdrivers and power drivers
• 18-8 stainless steel construction provides corrosion resistance in moderate-exposure environments
• Bright, uncoated finish maintains true stainless appearance with no plating to chip or flake
• No washer included; designed for direct fastening into countersunk or flat bearing surfaces

Compatibility

Designed as a standard 4-40 UNC machine screw for use in any application requiring a 4-40 threaded fastener with an oval head and Phillips drive configuration.

Installation Notes

Install using a Phillips screwdriver or Phillips bit driver sized for a number 1 or number 2 tip appropriate to the 4-40 head. A properly sized countersink in the mating material will seat the oval head flush or near-flush with the surface. Avoid overtightening in soft materials such as aluminum or plastic, as the small thread form can strip at low torque. Use a thread-locking compound if vibration resistance is required in the application.
