Value Collection R63034020 Machine Screw 1/4-20 Oval Head

Product Description

The VALUE COLLECTION R63034020 is a 1/4-20 x 1-1/2 inch oval head machine screw designed for secure, flush-finishing fastening in metal and other structural assemblies. Manufactured from grade 18-8 stainless steel with a bright, uncoated finish, this screw offers solid corrosion resistance in both indoor and outdoor environments. The Phillips drive allows for fast installation with standard tooling. Thread size follows UNC (Unified National Coarse) standards, making it compatible with the widest range of tapped holes and nuts. Overall length is 1-1/2 inches with length under head also measuring 1-1/2 inches, indicating no reduced shank.

This screw is used across a broad range of trade and industrial applications where a low-profile oval head countersink finish is required. Electricians, HVAC technicians, plumbers, and general contractors commonly use UNC machine screws like this for panel assembly, equipment enclosures, brackets, and access covers. The 18-8 stainless steel construction makes it well suited for applications with moderate moisture exposure, including pool equipment, outdoor enclosures, and coastal environments.

Key Features

• Grade 18-8 stainless steel construction for corrosion resistance in wet and outdoor environments
• Oval head profile provides a low-profile, countersunk appearance without fully recessing into the material
• Phillips drive for fast installation with common hand and power tools
• UNC 1/4-20 thread standard ensures broad compatibility with tapped holes and hex nuts
• Bright, uncoated finish with no added plating or treatment
• No washer — fastens directly against the work surface

Compatibility

Designed as a standard UNC machine screw for use in any application requiring a 1/4-20 threaded fastener with an oval Phillips head.

Installation Notes

Install using a Phillips screwdriver or compatible Phillips bit with a power driver. A properly sized countersink should be prepared in the mating material to allow the oval head to seat correctly. Ensure the mating hole or nut is tapped to 1/4-20 UNC specification before driving. Avoid overtightening, as stainless steel fasteners are susceptible to galling when excessive torque is applied without lubrication.
