Value Collection 580871PR Machine Screw 3/8-16 X 2.5 in

Product Description

The VALUE COLLECTION 580871PR is a 3/8-16 flat head slotted machine screw designed for general-purpose fastening in metal, wood, and composite assemblies. The screw measures 2.5 inches in overall length and is manufactured from Grade 2 steel with a zinc finish that provides basic corrosion resistance in light-duty indoor and sheltered environments. The flat head profile sits flush with or below the mating surface when countersunk correctly. The slotted drive accepts a standard flat-blade screwdriver. This screw follows the Unified National Coarse (UNC) thread standard at 3/8-16, making it a widely interchangeable fastener for production, maintenance, and repair work across mechanical and structural trades.

This machine screw is suited for residential and light commercial applications where a flush-mount fastener is required. Typical uses include equipment panel assembly, bracket mounting, and general mechanical repair where UNC-threaded holes or nuts are already present. The zinc finish makes it appropriate for dry or mildly humid indoor environments. It is not rated for outdoor marine or high-corrosion exposure. Installers in HVAC, plumbing, and electrical trades will recognize this as a standard hardware item for securing panels, junction boxes, brackets, and equipment enclosures.

Key Features

• 3/8-16 UNC thread for broad compatibility with standard tapped holes and hex nuts
• Flat head profile countersinks flush for a clean, low-profile installation
• Slotted drive works with standard flat-blade screwdrivers and bits
• Grade 2 steel construction provides adequate strength for general fastening applications
• Zinc finish delivers basic corrosion resistance in dry and sheltered environments
• 2.5 inch overall length suits medium-depth fastening applications

Compatibility

Designed as a standard UNC machine screw for use with any 3/8-16 threaded hole, nut, or insert conforming to Unified National Coarse thread specifications in inch-measurement fastener applications.

Installation Notes

This fastener is installed by qualified tradespeople and assemblers using standard hand tools or power drivers fitted with a flat-blade bit. Ensure the mating hole is properly tapped or threaded to 3/8-16 UNC before installation. For flush seating, use a correctly sized countersink to prepare the receiving surface. Do not overtighten, as Grade 2 steel has lower yield strength than higher-grade fasteners and is not intended for high-torque or high-tension structural joints.
