Measuring 7\/16-20 (UNF thread) with a 3-inch length under head, this fastener features partial threading and a zinc yellow dichromate finish that provides corrosion resistance in moderate-exposure environments. It conforms to ASME B18.2.1 dimensional standards. Sold in packages of 25, this screw is well-suited for maintenance crews, assembly technicians, and trade professionals who require dependable, specification-grade hardware.\u003c\/p\u003e\n\u003cp\u003eThe 39387 is appropriate for use in mechanical assemblies, equipment mounting, and structural connections where a fine-threaded, high-tensile fastener is required. The 7\/16-20 UNF thread pitch is commonly found in automotive, HVAC equipment frames, pump assemblies, and general industrial machinery. Partial threading ensures that the unthreaded shank bears shear loads effectively in clearance-hole applications. This screw is packaged in quantities of 25, making it practical for both single-job use and recurring maintenance stock.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction provides high tensile and proof load strength for demanding fastening applications\u003c\/li\u003e\n  \u003cli\u003e7\/16-20 UNF thread standard ensures compatibility with fine-threaded nuts and tapped holes in that size\u003c\/li\u003e\n  \u003cli\u003e3-inch length under head accommodates moderate stack thicknesses in structural or mechanical assemblies\u003c\/li\u003e\n  \u003cli\u003ePartial threading allows the unthreaded shank to carry shear loads in clearance-hole configurations\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish offers corrosion resistance and meets common industrial finishing specifications\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 for dimensional consistency and interchangeability\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 with 7\/16-20 UNF nuts, threaded inserts, or tapped holes in mechanical and structural assemblies requiring Grade 8 fastener strength.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or technician familiar with torque specifications for Grade 8 fasteners in the applicable assembly.
