Value Collection 94653 4-40 X 1/2 in Pan Head Phillips Screw

Product Description

The VALUE COLLECTION 94653 is a 4-40 UNC machine screw designed for precision fastening in light mechanical assemblies, electrical enclosures, and instrumentation panels. The pan head profile provides a low-profile bearing surface suited for thin material applications, while the Phillips drive allows standard installation with common hand and power tools. Constructed from Grade 18-8 stainless steel with a bright, uncoated finish, this screw resists corrosion in mildly harsh environments. Measuring 0.5 inches in length under the head with a 4-40 thread form, it is sized for small-component fastening tasks common across electrical, HVAC control panel, and light mechanical service work.

This fastener is used in residential and commercial applications wherever a small-diameter, corrosion-resistant machine screw is required. Typical use cases include securing control boards, terminal strips, junction box covers, instrumentation housings, and sheet metal panels. Electricians, HVAC technicians, and mechanical assemblers commonly stock this size for panel and component work. The 4-40 thread size is a standard inch-series thread widely used in electronics and light mechanical assemblies. The screws are sold individually with a minimum order quantity of 50 pieces.

Key Features

• 4-40 UNC thread form — standard inch-series size for electronics and control panel fastening
• Pan head profile with Phillips drive for broad tool compatibility
• Grade 18-8 stainless steel construction for corrosion resistance
• Bright, uncoated finish — no added coating that could affect thread fit in tapped holes
• Length under head: 0.5 inches — suitable for thin-material fastening applications
• Sold without washer for direct thread-to-material installations

Compatibility

Designed as a standard 4-40 UNC machine screw compatible with any tapped or threaded insert accepting a 4-40 inch-series thread. Typical fitment includes control boards, electrical enclosures, instrumentation panels, and light mechanical assemblies using 4-40 threaded holes.

Installation Notes

Installation is performed with a standard Phillips screwdriver or a Phillips bit in a power driver set to a low torque setting to avoid stripping the small-diameter thread. Ensure the receiving hole is properly tapped to 4-40 UNC before driving. When used in electrical panels or control boards, de-energize all circuits before service per applicable NEC guidelines. Avoid over-torquing, as the small thread diameter is susceptible to shear under excessive force.
