At 2 inches in length under head, the fastener is partially threaded and conforms to ASME B18.2.1 dimensional standards. Grade 8 steel provides high tensile strength suitable for demanding structural and mechanical applications. The zinc yellow dichromate coating adds corrosion resistance while providing a distinctive yellow-tinted appearance that aids in visual identification. These screws are installed using a standard hex wrench or socket driver and are sold in packs of 50.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for use in industrial, mechanical, and structural assemblies where fine-thread engagement and high-strength fastening are required. The 1\/4-28 UNF thread pitch offers greater thread engagement per inch compared to coarse-thread equivalents, making it a common choice in applications where vibration resistance or thinner-walled materials are a factor. Typical installers include millwrights, maintenance mechanics, and fabricators working on equipment, fixtures, and metal assemblies.\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\/4-28 UNF fine-thread profile conforming to ASME B18.2.1\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank — 2 inches length under head\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish provides corrosion resistance and visual identification\u003c\/li\u003e\n  \u003cli\u003eSold in a 50-piece pack for shop stock and production 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 for use in any application requiring an ASME B18.2.1 compliant fastener with Grade 8 steel strength and a 2-inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a standard hex socket or open-end wrench sized to the 1\/4-inch hex head. Ensure mating threads are clean and free of debris before installation. Do not exceed the proof load rating of Grade 8 fasteners by over-torquing in softer base materials.
