It measures 2.5 inches in overall length and is produced to ASME B18.6.3 and SAE J82 standards, ensuring dimensional consistency and mechanical reliability. The flat head seats flush with the mating surface when installed in a countersunk hole. This fastener is appropriate for general mechanical assembly, structural bracketing, and fabrication work across industrial, HVAC, plumbing, and electrical enclosure applications. Installation is performed by licensed trades and maintenance professionals using standard slotted drivers or bits.\u003c\/p\u003e\n\u003cp\u003eThis machine screw is suited for applications requiring a flush-mount fastener in countersunk steel, aluminum, or structural plastic components. Common use scenarios include panel assembly, equipment mounting brackets, and enclosure construction in commercial and light industrial settings. The 1\/2-13 thread size is a standard coarse-thread designation widely used across mechanical and trade applications. No washer is included or required by the standard specification for this fastener style.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-13 unified coarse thread for broad compatibility with standard tapped holes\u003c\/li\u003e\n  \u003cli\u003eFlat head profile seats flush in countersunk applications\u003c\/li\u003e\n  \u003cli\u003eSlotted drive for use with standard flat-blade drivers or bits\u003c\/li\u003e\n  \u003cli\u003eSteel construction with zinc finish for basic corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.6.3 and SAE J82 dimensional and material standards\u003c\/li\u003e\n  \u003cli\u003e2.5 inches overall length with no washer style designation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/2-13 coarse-thread machine screw suitable for use in any application requiring an ASME B18.6.3-compliant flat head slotted fastener in that thread size and length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a properly countersunk or counterbored mating hole to seat the flat head flush.
