Value Collection SBFI03100750-100BX 5/16-18 X 3/4 in Flat Head Screw

Product Description

The VALUE COLLECTION SBFI03100750-100BX is a 5/16-18 x 3/4-inch flat head slotted machine screw made from Grade 2 steel with a zinc-plated finish. The flat head profile sits flush with the mating surface when fully seated, making it suitable for assemblies where a low-profile fastener is required. The slotted drive accepts a standard flat-blade screwdriver. These screws follow Unified National Coarse (UNC) thread standards and are sold in a box of 100. Electricians, HVAC technicians, plumbers, and general contractors reach for this screw type in panel assemblies, bracket mounting, and equipment enclosure work.

This screw is commonly used in light-duty mechanical and electrical assembly applications where flush seating is needed. Typical install scenarios include securing cover plates, mounting brackets, junction box hardware, and equipment panels. The zinc plating provides basic corrosion resistance for indoor and sheltered installations. The 3/4-inch overall length and 5/16-18 UNC thread are measured by overall length including the head.

Key Features

• 5/16-18 UNC thread for standard inch-system fastening applications
• 3/4-inch overall length with flat head profile for flush-mount installations
• Slotted drive compatible with standard flat-blade screwdrivers
• Grade 2 steel construction for light-duty mechanical assemblies
• Zinc-plated finish for basic corrosion protection in sheltered environments
• Sold in a box of 100 for bench stock and service van stocking

Compatibility

Designed for general-purpose use in standard 5/16-18 UNC tapped holes found in light-duty mechanical, electrical, and HVAC panel assemblies.

Installation Notes

Install with a flat-blade screwdriver sized to the slotted head. Ensure the mating hole is properly tapped to 5/16-18 UNC before driving the screw. Do not overtighten Grade 2 fasteners, as they have lower proof strength than Grade 5 or Grade 8 hardware. Power down any electrical equipment before working in panels or enclosures where these screws are being installed or replaced.
