This fastener features a 5\/16-18 UNC thread size with a 2-3\/4 inch length under head. It is manufactured from Grade 2 steel with a zinc-plated finish that provides a basic level of corrosion resistance. The partial threading allows the unthreaded shank to act as a shoulder, making it well suited for applications where shear load, alignment, or controlled clamping is required. Installation is performed using a 1\/2 inch hex key or appropriate wrench.\u003c\/p\u003e\u003cp\u003eThis cap screw is used across a wide range of residential and commercial trade applications including HVAC equipment assembly, plumbing fixture mounting, electrical panel and enclosure fastening, and general mechanical assembly. Anywhere a reliable, standard-inch threaded fastener is needed for load-bearing or structural connections, this screw fills that role. It is a staple fastener for service technicians and maintenance professionals working with inch-measurement hardware.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/16-18 UNC thread standard  -  widely compatible with inch-measurement hardware\u003c\/li\u003e\n\u003cli\u003e2-3\/4 inch length under head for deeper engagement in thicker assemblies\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank provides shear resistance and alignment support\u003c\/li\u003e\n\u003cli\u003eGrade 2 steel construction suitable for general-purpose fastening loads\u003c\/li\u003e\n\u003cli\u003eZinc-plated finish adds basic corrosion and oxidation resistance\u003c\/li\u003e\n\u003cli\u003e1\/2 inch hex key size for standard wrench or socket installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard inch-series UNC hex head cap screw for general mechanical and structural fastening applications wherever a 5\/16-18 partially threaded fastener is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified technician familiar with fastener torque requirements for Grade 2 steel hardware.
