Value Collection 580431PR Flat Head Machine Screw 10-24

Product Description

The VALUE COLLECTION 580431PR is a 10-24 UNC flat head machine screw designed for general-purpose fastening in metal and plastic assemblies. Measuring 1 inch in overall length, it features a slotted drive and a countersunk flat head profile that sits flush with or below the work surface when installed. Constructed from Grade 2 steel with a zinc finish for basic corrosion resistance, this screw is suited for light-duty mechanical and structural applications where a clean, low-profile fastener is required. Sold in minimum order quantities of 100 per order with a package quantity of 1.

This fastener is commonly used in electrical enclosures, control panels, light fabrication, HVAC equipment housings, and general sheet metal or machined-part assemblies. The 10-24 UNC thread is one of the most widely used coarse-thread machine screw sizes in North American trade work, making it a practical stocking item for service vehicles and shop inventory. The flat head profile is appropriate for countersunk hole applications where fastener protrusion must be minimized.

Key Features

• 10-24 UNC coarse thread for broad compatibility with tapped holes and standard hex nuts
• Flat countersunk head seats flush with the mating surface
• Slotted drive compatible with standard flat-blade screwdrivers
• Grade 2 steel construction meets general-purpose mechanical strength requirements
• Zinc finish provides basic corrosion protection in dry indoor environments
• 1 inch overall length with full thread engagement along the shank

Compatibility

Designed as a standard 10-24 UNC flat head machine screw suitable for use with any tapped hole or threaded insert conforming to the 10-24 Unified National Coarse thread standard.

Installation Notes

Installation requires a flat-blade screwdriver sized to the slotted drive. When used in countersunk applications, verify the hole chamfer angle matches the screw head angle to ensure proper seating and clamping force. De-energize any equipment before fastening components within electrical enclosures, per NEC guidelines. Do not overtighten Grade 2 fasteners in soft base materials such as aluminum or plastic.
