Value Collection W55192PS 4-40 X 0.5in Pan Head Phillips Screw

Product Description

The VALUE COLLECTION W55192PS is a 4-40 UNC machine screw with a pan head and Phillips drive, manufactured from Grade 316 stainless steel with a bright, uncoated finish. The screw measures 0.5 inches in length under the head, making it suitable for tight-clearance assemblies and precision fastening tasks. Grade 316 stainless steel provides strong resistance to corrosion and oxidation, including exposure to chlorides and marine environments. This fastener is used by maintenance technicians, electricians, HVAC service professionals, and mechanical contractors for panel, equipment, and enclosure assembly work where corrosion resistance is a priority.

This screw is suited for light-duty fastening applications in electrical enclosures, HVAC control panels, instrumentation housings, and similar equipment assemblies. The 4-40 thread size and pan head profile make it compatible with standard tapped holes and nuts in thin-gauge metal and plastic substrates. It is sold in a minimum order quantity of 50 pieces per order, with each package containing 1 unit per the supplier pack configuration. Applications range from residential and commercial HVAC equipment to industrial panel fabrication and control board mounting.

Key Features

• Grade 316 stainless steel construction for superior corrosion and chloride resistance
• 4-40 UNC thread for compatibility with standard tapped hardware in light-gauge assemblies
• Pan head profile distributes clamping load across the fastened surface
• Phillips drive for quick installation with standard hand or power tools
• Bright, uncoated finish — no additional surface treatment that could affect dimensional tolerances
• 0.5-inch length under head suits thin-material and shallow-boss fastening applications

Compatibility

Designed as a standard 4-40 UNC machine screw for use in any application requiring a pan head Phillips fastener with a 0.5-inch length under head in Grade 316 stainless steel.

Installation Notes

Installation is performed by the relevant trade technician using a Phillips-head screwdriver or compatible power driver bit sized for a 4-40 screw. Always power down or de-energize any electrical or control panel assembly before inserting or removing fasteners. Do not overtighten in plastic or thin-gauge metal substrates, as the 4-40 thread form is susceptible to stripping under excessive torque. Follow applicable NEC or equipment manufacturer guidelines for panel and enclosure assembly.
