Value Collection MSC-67571083 4-40 X 3/4 in Pan Head Phillips Screw

Product Description

The VALUE COLLECTION MSC-67571083 is a 4-40 UNC machine screw designed for precision fastening applications where corrosion resistance and reliable thread engagement are required. Measuring 3/4 inches in length under the head, this pan head Phillips drive fastener is manufactured from Grade 18-8 stainless steel with a bright, uncoated finish. The pan head profile provides a low-profile, wide bearing surface well suited to sheet metal, electronics enclosures, and light mechanical assemblies. It is installed by technicians and assemblers working in environments where ferrous hardware is not acceptable.

This screw is suited for light-duty mechanical, electrical, and electronic assembly work. The 4-40 thread designation is one of the most common small-diameter unified coarse thread (UNC) standards in North American trade and OEM manufacturing. It is widely used in control panel fabrication, instrumentation mounting, HVAC control board enclosures, and electrical junction box work where small-diameter stainless fasteners are specified. The Phillips drive is compatible with standard No. 1 Phillips screwdrivers and power bit drivers.

Key Features

• Grade 18-8 stainless steel construction resists corrosion and oxidation in damp or chemically active environments
• 4-40 UNC thread provides reliable engagement in tapped holes and standard 4-40 nuts
• Pan head profile offers a wide, flat bearing surface with a rounded top for low-profile installations
• Phillips drive accepts standard No. 1 Phillips bits for hand and power tool installation
• Bright, uncoated finish maintains dimensional consistency and avoids plating buildup on threads
• Length measured under head at 3/4 inches for consistent grip-length calculations

Compatibility

Designed as a standard UNC fastener compatible with any 4-40 tapped hole or 4-40 threaded insert per ASME B1.1 specifications.

Installation Notes

Install using a No. 1 Phillips screwdriver or matching power driver bit to avoid cam-out and head damage. De-energize any electrical assembly before fastening or removing hardware in live enclosures. Apply thread-locking compound only if specified by the assembly drawing, as it may interfere with disassembly during service. Do not overtighten into plastic or thin sheet metal; use a torque-limiting driver when the substrate material requires it.
