Value Collection 580331PR 8-32x1 Flat Slotted Machine Screw

Product Description

The VALUE COLLECTION 580331PR is a flat head slotted machine screw designed for general fastening applications in metal, plastic, and composite assemblies. It features an 8-32 Unified National Coarse (UNC) thread and a 1-inch overall length, making it a standard choice for light-duty mechanical assemblies. The screw is manufactured from Grade 2 steel with a zinc finish that provides basic corrosion resistance. The flat head profile sits flush with or below the surface of a countersunk hole, which is useful in assemblies where a low-profile fastener is required. Installation requires a standard flat-blade screwdriver or a matching slotted bit driver.

This screw is suited for use in light mechanical assemblies, electrical enclosures, HVAC equipment panels, and general sheet metal work. The 8-32 thread size is one of the most common machine screw sizes found in control boards, junction boxes, and equipment mounting applications across residential and commercial trades. It is supplied in multiples of 100 units per order, making it practical for service technicians and shop stock replenishment.

Key Features

• 8-32 UNC thread for compatibility with standard tapped holes and threaded inserts
• Flat head profile sits flush in countersunk applications
• Slotted drive accepts standard flat-blade screwdrivers and bits
• Grade 2 steel construction for general-purpose fastening
• Zinc finish provides basic corrosion resistance
• 1-inch overall length with full thread engagement along the shank

Compatibility

Designed as a general-purpose replacement or service fastener for any application requiring an 8-32 UNC flat head slotted machine screw with a 1-inch overall length.

Installation Notes

Installation is performed with a standard flat-blade screwdriver or matching slotted bit driver sized for an 8-32 screw head. Ensure mating tapped holes or threaded inserts are clean and free of debris before driving. Do not overtighten, as Grade 2 steel fasteners have lower yield strength than higher-grade hardware. When used in electrical enclosures or control panel assemblies, de-energize all circuits before beginning fastener work in accordance with applicable NFPA 70 (NEC) lockout and tagout procedures.
