Value Collection R63068121 Machine Screw 1/4-20 X 1.5 in

Product Description

The VALUE COLLECTION R63068121 is a 1/4-20 x 1.5-inch flat head Phillips machine screw manufactured from 18-8 stainless steel with a bright, uncoated finish. Designed to sit flush with or below the mating surface, the flat head profile is suited for applications where a countersunk hole is pre-drilled or required by design. The 1/4-20 Unified National Coarse thread pattern provides reliable engagement in standard tapped holes. The 18-8 stainless steel construction delivers corrosion resistance appropriate for indoor and moderate outdoor environments. This fastener is installed by electricians, HVAC technicians, plumbers, and general trade professionals as part of equipment assembly, panel mounting, and structural fastening tasks.

This screw is appropriate for use in light industrial, commercial, and residential trade applications where a countersunk, flush-mount fastener is required. Common install scenarios include securing electrical enclosure panels, HVAC equipment brackets, plumbing fixture hardware, and mechanical assemblies that require a clean, flush surface finish. The UNC thread form is compatible with standard 1/4-20 tapped holes and threaded inserts commonly found in trade equipment and fixtures. These screws are sold in minimum order quantities of 100 units.

Key Features

• 1/4-20 UNC thread for compatibility with standard tapped holes and threaded inserts

• Flat head profile seats flush in countersunk holes for a clean surface finish
• Phillips drive works with standard Phillips bits and screwdrivers
• 18-8 stainless steel construction provides corrosion resistance without a coating
• Bright, uncoated finish maintains dimensional accuracy at the thread and head

Compatibility

Designed as a standard 1/4-20 UNC flat head Phillips machine screw suitable for use in any application requiring a countersunk stainless steel fastener with a 1/4-20 thread and 1.5-inch overall length.

Installation Notes

Install using a properly sized Phillips screwdriver or Phillips bit rated for 1/4-inch fasteners to avoid cam-out and head damage. Ensure the receiving hole is countersunk to the correct angle for a flat head screw before installation. Do not overtighten into soft substrates or thin panels, as stainless steel threads can gall under excessive torque. Always verify thread engagement depth is adequate before applying load.
