Value Collection 94504 4-40 X 3/4 in Flat Head Phillips Screw

Product Description

The VALUE COLLECTION 94504 is a 4-40 x 3/4 inch flat head Phillips machine screw manufactured from 18-8 stainless steel with a bright, uncoated finish. This fastener features unified national coarse (UNC) threading and is sized for applications requiring a flush or countersunk seating surface. The flat head profile sits flush with or below the material surface when installed in a properly countersunk hole. At 3/4 inch overall length with full-thread engagement to the head, this screw suits precision assembly tasks across HVAC, electrical, plumbing, and general mechanical work where corrosion resistance and reliable thread engagement are required.

This screw is well suited for light-gauge metal panels, junction boxes, electrical enclosures, and equipment covers where 4-40 threading is specified. The 18-8 stainless steel construction provides solid corrosion resistance in both indoor and outdoor environments. Trade professionals and maintenance technicians use this fastener for equipment reassembly, panel mounting, and control-box work where a flush finish is needed and stainless material is preferred over zinc-plated alternatives. Sold in a minimum order quantity of 100 pieces per order.

Key Features

• 4-40 UNC thread for precise, standard mechanical fastening
• Flat head profile for flush or countersunk installations
• Phillips drive for quick installation with standard hand and power tools
• 18-8 stainless steel construction for corrosion resistance in wet or outdoor-exposed assemblies
• Bright, uncoated finish with no additional coating that could affect thread tolerance
• 3/4 inch overall length with full-thread engagement from head to tip

Compatibility

Designed as a standard 4-40 UNC flat head Phillips machine screw compatible with any tapped hole or threaded insert specifying 4-40 unified national coarse thread in inch-measurement fastener applications.

Installation Notes

Installation is typically performed by maintenance technicians, electricians, or mechanical assemblers using a Phillips-head screwdriver or appropriate bit driver. Ensure the receiving hole is properly tapped to 4-40 UNC specification or fitted with a matching threaded insert before driving the screw. For countersunk applications, use a correctly sized countersink bit to allow the flat head to seat flush. Avoid overtightening, which can strip 18-8 stainless threads in soft base materials.
