Partially threaded along the shank, it delivers high tensile strength suitable for demanding fastening applications in mechanical assemblies, equipment mounting, and structural connections. The zinc yellow dichromate finish provides corrosion resistance while meeting ASME B18.2.1 dimensional standards. This screw is appropriate for use by machinists, maintenance technicians, millwrights, and general tradespeople working with inch-series fasteners.\u003c\/p\u003e\u003cp\u003eThis cap screw is suited for general industrial and mechanical applications where high-strength inch-series fasteners are required. Typical uses include securing machine components, brackets, frames, and assemblies where a hex drive and partial threading provide firm clamping without thread engagement through the full grip length. The 5\/16-18 UNC thread series is widely used across industrial equipment, HVAC mounting hardware, and structural mechanical assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 8 steel construction for high tensile and proof load strength\u003c\/li\u003e\n\u003cli\u003e5\/16-18 UNC thread for broad inch-series compatibility\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank provides a solid grip zone under the head\u003c\/li\u003e\n\u003cli\u003eZinc yellow dichromate finish offers corrosion and oxidation resistance\u003c\/li\u003e\n\u003cli\u003eMeets ASME B18.2.1 dimensional standards for hex head cap screws\u003c\/li\u003e\n\u003cli\u003e2-inch length under head suits a range of medium-depth fastening applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard inch-series hex head cap screw compatible with any 5\/16-18 UNC tapped hole or nut per ASME B18.2.1 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall using a standard hex wrench or socket driver sized for a 5\/16-18 UNC cap screw.
