It measures 3 inches under the head and is partially threaded, conforming to ASME B18.2.1 dimensional standards. Grade 8 steel delivers high tensile strength suitable for demanding fastening applications, while the zinc yellow dichromate coating provides corrosion resistance. This fastener is installed by mechanics, millwrights, and maintenance technicians working on assemblies that require a strong, standardized inch-series fastener.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for industrial, mechanical, and structural fastening applications where a fine-thread 1\/2-20 UNF pattern is specified. The partial threading allows for consistent clamping load across thicker joint stacks. Typical uses include equipment assemblies, machinery mounting, and general MRO applications requiring Grade 8 strength and ASME B18.2.1 compliance. Sold individually with a minimum order quantity of 10 pieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003e1\/2-20 UNF fine thread provides precise fastening control and vibration resistance\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish offers corrosion protection in moderate service environments\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank supports accurate clamping in thick-joint assemblies\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 for consistent dimensional tolerances\u003c\/li\u003e\n  \u003cli\u003e3-inch length under head suits a range of mid-depth fastening applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series hex head cap screw for use in any application calling for a 1\/2-20 UNF Grade 8 fastener conforming to ASME B18.2.1.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified mechanics or maintenance technicians using a standard hex wrench or socket.
