It features a pan head profile with a Phillips drive and is manufactured from Grade 2 steel with a zinc-plated finish for basic corrosion resistance. The screw measures 5\/16 inches in length under the head, making it well suited for securing panels, enclosures, and small components where a low-profile head is required. This box contains 100 pieces, packaged for job-site or shop use. Installation is straightforward with a standard Phillips screwdriver or bit driver.\u003c\/p\u003e\n\u003cp\u003eThis fastener is commonly used in HVAC equipment panels, electrical enclosures, control board mounting, and light-duty sheet metal or plastic assemblies. The 4-40 thread size is a standard coarse-thread UNC designation used widely in instrumentation, small appliances, and commercial equipment. Tradespeople and technicians working on control panels, junction boxes, or equipment covers will find this screw a standard replacement or stocking item. The pan head sits flush against flat surfaces without requiring a countersink, keeping installation quick and clean.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-40 UNC thread size — standard coarse thread for small fastener applications\u003c\/li\u003e\n  \u003cli\u003ePan head profile — low profile, no countersink required\u003c\/li\u003e\n  \u003cli\u003ePhillips drive — compatible with standard Phillips screwdrivers and bit drivers\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction — adequate strength for light-duty mechanical assemblies\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish — provides basic corrosion resistance in indoor environments\u003c\/li\u003e\n  \u003cli\u003e5\/16-inch length under head — suits thin panel and enclosure fastening\u003c\/li\u003e\n  \u003cli\u003eBox of 100 — stocking quantity for shop or field use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 4-40 UNC pan head machine screw suitable for general-purpose use in electrical enclosures, HVAC control panels, instrumentation housings, and light mechanical assemblies requiring a Phillips-drive fastener without a washer.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a Phillips screwdriver or bit driver sized to the fastener.
