Built to Grade 8 steel specifications, this fastener delivers superior tensile strength compared to lower-grade alternatives, making it appropriate for high-load assemblies and vibration-prone environments. The zinc yellow dichromate finish provides corrosion resistance while serving as a visual identifier for Grade 8 classification. Thread size is 1\/4-28 UNF with a 3\/4-inch length under head, conforming to ASME B18.2.1 dimensional standards. Sold in a package of 50 pieces.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for use in precision mechanical assemblies, equipment repair, and structural connections where fine-thread engagement and high clamping force are required. The 1\/4-28 UNF thread pitch is common in automotive, HVAC equipment frames, electrical enclosures, and light industrial machinery. Licensed tradespeople and maintenance technicians installing or servicing equipment will find this screw appropriate for applications demanding a standardized, torque-rated fastener with documented material grade and finish.\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\u003eZinc yellow dichromate finish for corrosion resistance and grade identification\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank along the 3\/4-inch length under head\u003c\/li\u003e\n  \u003cli\u003e1\/4-28 UNF fine thread for improved fastening torque and vibration resistance\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.1 dimensional standards for hex head cap screws\u003c\/li\u003e\n  \u003cli\u003ePackaged in quantities of 50 for service stock and job-site use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-28 UNF hex head cap screw conforming to ASME B18.2.1, suitable for any application specifying a Grade 8 fastener in that thread size and length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified technician familiar with proper fastener torque procedures for Grade 8 hardware.
