Value Collection MSFI03704000-050B 3/8-16 X 4 in Flat Head Screw

Product Description

The VALUE COLLECTION MSFI03704000-050B is a 3/8-16 x 4 inch flat head slotted machine screw made from Grade 2 steel with a zinc-plated finish. It features a UNC (Unified National Coarse) thread form and is measured by overall length at 4 inches, which is also the full length under the head. The flat head profile sits flush with or below the surface of the mated material, making it well suited for countersunk applications. The zinc plating provides basic corrosion resistance for general indoor and light-duty outdoor use. This fastener is sold in a minimum order quantity of 50 pieces.

This screw is used across a wide range of light-duty mechanical assembly, electrical enclosure work, HVAC equipment panels, and general trade fabrication where a flush-mount fastener with a standard slotted drive is required. Grade 2 steel is appropriate for low- to medium-stress applications. Installers working on equipment panels, junction boxes, brackets, and similar sheet metal or light structural assemblies will find this screw a standard fit for those tasks.

Key Features

• 3/8-16 UNC thread for broad compatibility with standard tapped holes and nuts
• Flat head design allows flush or countersunk seating
• Slotted drive compatible with standard flathead screwdrivers
• Zinc-plated finish for basic corrosion resistance
• Grade 2 steel construction suitable for general-purpose fastening
• 4 inch overall length with full 4 inch length under head

Compatibility

Designed as a general-purpose UNC machine screw for use in standard 3/8-16 tapped holes across residential and light commercial equipment, enclosures, and structural assemblies.

Installation Notes

Installation is performed with a standard flathead screwdriver or slotted bit driver. De-energize any electrical equipment and follow applicable NEC guidelines before fastening within or near electrical enclosures. Use the appropriate countersink angle in the mating material to ensure full flat head seating. Do not exceed the load ratings appropriate for Grade 2 fasteners in structural or high-vibration applications.
