It measures 1\/2 inch in length under the head and is driven with a hex tool. Conforming to ASME B18.13a and SAE J82 standards, this screw is suited for mechanical assemblies, electrical enclosures, and general industrial fastening applications. It is sold in minimum order quantities of 100 pieces per package, making it appropriate for shop stock, service vehicle inventory, or production line use.\u003c\/p\u003e\n\u003cp\u003eThis fastener is used across a wide range of trade applications including HVAC equipment assembly, electrical panel work, plumbing fixture mounting, and general mechanical installations. The zinc finish provides basic corrosion resistance in dry to mildly humid indoor environments. The external tooth washer style helps resist loosening under vibration, which is relevant in equipment with rotating components or frequent thermal cycling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 thread size in the inch measurement system\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch length under head for precise fastening depth\u003c\/li\u003e\n  \u003cli\u003eHex head and hex drive for wrench or socket installation\u003c\/li\u003e\n  \u003cli\u003eExternal tooth washer style resists loosening under vibration\u003c\/li\u003e\n  \u003cli\u003eSteel construction with zinc finish for corrosion resistance in dry environments\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.13a and SAE J82 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-20 inch-series machine screw suitable for use in equipment panels, brackets, enclosures, and assemblies that require a hex head fastener with an external tooth lock washer configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a hex wrench, socket, or nut driver sized to the hex head.
