Value Collection SBFI03704000-050BX Machine Screw 3/8-16x4in

Product Description

The VALUE COLLECTION SBFI03704000-050BX is a 3/8-16 x 4-inch flat head slotted machine screw manufactured from Grade 2 steel with a zinc-plated finish. The flat head profile sits flush with or below the mating surface when properly countersunk, making it a standard choice in assemblies where a low-profile fastener is required. The slotted drive accommodates a standard flat-blade screwdriver. The zinc coating provides basic corrosion resistance suitable for general indoor and light-duty applications. This fastener uses Unified National Coarse (UNC) threading and is sold in a minimum order box of 50 pieces.

This screw is suited for general mechanical assembly, fabrication, and maintenance work across light industrial, HVAC equipment panels, electrical enclosures, and similar trade applications. The 3/8-16 UNC thread is a widely used coarse-thread standard that engages tapped holes or hex nuts readily available in the field. The 4-inch overall length covers applications requiring deeper thread engagement or longer grip length through stacked materials or panels.

Key Features

• 3/8-16 UNC coarse thread for broad compatibility with standard tapped holes and hardware
• Flat head design allows flush or countersunk installation in mating surfaces
• Slotted drive accepts standard flat-blade screwdrivers
• Grade 2 steel construction for general-purpose strength requirements
• Zinc-plated finish for basic corrosion protection in dry or light-moisture environments
• 4-inch overall length with full 4-inch length under head

Compatibility

Designed as a standard 3/8-16 UNC machine screw for use in any application requiring a flat head slotted fastener of this thread size and length, including equipment panels, brackets, and general mechanical assemblies.

Installation Notes

Installation is typically performed by mechanical assemblers, HVAC technicians, electricians, or plumbers during equipment assembly or field repair. A properly sized countersink in the mating material is required for the flat head to seat flush. Use the correct flat-blade screwdriver bit matched to the slot width to avoid cam-out and head damage. De-energize and lock out any equipment before fastening components to live panels or enclosures.
