Value Collection R63060448 Flat Head Machine Screw 1/4-20

Product Description

The VALUE COLLECTION R63060448 is a 1/4-20 x 1-1/2 inch flat head slotted machine screw manufactured from 18-8 stainless steel with a bright, uncoated finish. The flat head profile sits flush with the mating surface when countersunk, making it well suited for applications where a smooth, low-profile fastening point is required. The 1/4-20 Unified National Coarse thread form provides reliable engagement across a wide range of materials. This screw is sold in a minimum order quantity of 100 pieces per order and is commonly specified by maintenance technicians, electricians, plumbers, and HVAC service professionals for panel assemblies, equipment enclosures, and structural brackets.

This fastener is appropriate for both commercial and light industrial applications where corrosion resistance is a priority. The 18-8 stainless steel construction resists oxidation in moderate moisture environments, making it a practical choice for outdoor equipment, wet mechanical rooms, pool equipment enclosures, and coastal installations. The slotted drive accepts a standard flat-blade screwdriver, and the overall length of 1-1/2 inches accommodates typical panel thicknesses found in HVAC equipment, electrical enclosures, and plumbing access covers.

Key Features

• 1/4-20 UNC thread form for broad compatibility with standard tapped holes and nuts
• Flat head countersunk profile for flush-mount installations
• Slotted drive for use with standard flat-blade screwdrivers
• 18-8 stainless steel construction provides corrosion resistance in damp or outdoor environments

Compatibility

Designed as a standard 1/4-20 UNC inch-series machine screw for use wherever a flat head slotted fastener is specified in equipment assembly, panel mounting, or maintenance repair applications. No specific model compatibility was stated in the product data.

Installation Notes

Installation requires a properly sized countersunk hole to seat the flat head flush with the mating surface. A flat-blade screwdriver sized to the slot is required; an undersized blade can damage the drive and complicate removal. Power down and de-energize any electrical or HVAC equipment before accessing fastened panels or covers. Follow applicable NEC or equipment-manufacturer guidelines when fastening within electrical enclosures.
