Value Collection R63068246 Flat Head Phillips Screw 1/4-20

Product Description

The VALUE COLLECTION R63068246 is a 1/4-20 x 3-inch flat head Phillips machine screw manufactured from grade 18-8 stainless steel with a bright, uncoated finish. It features a unified national coarse (UNC) thread form and is measured by overall length, placing the full 3-inch dimension from tip to head. The flat head profile sits flush with or below the mating surface when installed in a countersunk hole. This fastener is suited for general mechanical assembly work in corrosive or high-moisture environments where stainless steel is preferred over plated carbon steel.

This screw is used in a wide range of light industrial, HVAC equipment, plumbing fixture, and electrical enclosure assembly applications. Its 1/4-20 UNC thread is one of the most common coarse-thread sizes in North American trade work, making it a standard grab-and-go fastener for service technicians and assemblers across multiple disciplines. The Phillips drive is compatible with standard no. 2 Phillips bits and screwdrivers. No washer is included or required for the standard countersunk installation.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard tapped holes and nuts
• 3-inch overall length suits deep-reach or through-bolt assembly applications
• Flat head design sits flush when installed in a properly countersunk hole
• Phillips drive compatible with no. 2 Phillips bits and standard screwdrivers
• Grade 18-8 stainless steel provides corrosion resistance without plating
• Bright uncoated finish — no coating to chip, flake, or contaminate assemblies

Compatibility

Designed as a standard 1/4-20 UNC flat head Phillips machine screw for use in any application requiring that thread size, head style, and drive type.

Installation Notes

Installation is performed by service technicians and assemblers using a no. 2 Phillips bit or hand screwdriver. The mating hole should be countersunk to the correct angle to seat the flat head flush. Apply fastener torque appropriate for the joint material and stainless steel galling risk — consider anti-seize compound when threading into stainless tapped holes to prevent galling. Always de-energize and lock out equipment before accessing fastened electrical or mechanical enclosures.
