Value Collection 580883PR 3/8-16 X 3.5 in Flat Head Slotted Screw

Product Description

The VALUE COLLECTION 580883PR is a 3/8-16 x 3.5 inches overall length machine screw designed for general-purpose fastening in metal, wood, and composite assemblies. It features a flat head profile with a slotted drive, allowing installation with a standard flat-blade screwdriver. Manufactured from steel with a zinc finish for basic corrosion resistance, this screw meets ASTM Grade 2 material standards and uses Unified National Coarse (UNC) thread form. It is sold individually per package with a minimum order quantity of 50 pieces, making it a practical choice for high-volume fastening applications in mechanical, electrical, and structural work.

This machine screw is suited for use in residential and light commercial maintenance, panel assembly, equipment mounting, and general mechanical work. The flat head sits flush or countersunk in the mating material, making it appropriate where a low-profile fastener is required. The 3/8-16 UNC thread is one of the most widely used coarse thread sizes in inch-system applications, commonly found in machinery, enclosures, and fabricated steel components. Tradespeople working in HVAC, electrical, or plumbing service often use this screw size for equipment brackets, cover panels, and junction box hardware.

Key Features

• 3/8-16 UNC coarse thread for broad compatibility with standard inch-system tapped holes
• 3.5 inches overall length provides substantial grip depth for thicker assemblies
• Flat head profile allows flush or countersunk installation in prepared surfaces
• Slotted drive works with standard flat-blade screwdrivers and bit drivers
• Zinc finish provides basic corrosion resistance for indoor and protected outdoor use
• Grade 2 steel construction meets general-purpose structural fastening requirements

Compatibility

Designed for use in any application requiring a 3/8-16 UNC inch-system machine screw with a flat head and slotted drive. Suitable for steel, aluminum, and other materials with pre-tapped or nut-threaded holes in standard 3/8-16 UNC thread form.

Installation Notes

Install using a flat-blade screwdriver or slotted bit driver sized appropriately for the head. For countersunk applications, ensure the receiving material is pre-drilled and countersunk to match the flat head angle before driving. Do not overtighten Grade 2 fasteners in tapped aluminum or soft materials, as thread stripping can occur. De-energize any equipment and follow applicable NEC or facility lockout-tagout procedures before fastening components to live panels or energized enclosures.
