This fastener features a partially threaded shank and is manufactured from Grade 8 steel with a zinc-plated finish for corrosion resistance. At 4.5 inches in length under the head with a Unified National Coarse (UNC) thread standard, it delivers the tensile strength needed for high-load joints. Compliance with ASTM A354 BD confirms the fastener meets established material and mechanical property standards. Installers across trades use Grade 8 hardware where standard fasteners would not provide sufficient clamping force.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for general mechanical assembly, equipment mounting, and structural fastening in residential and commercial trade applications. The partial threading is appropriate for through-bolt connections and clamped joint assemblies where the unthreaded shank spans the grip length of the joint. This fastener is sold in packages of 10 units, making it practical for jobsite use or maintaining working inventory.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile strength in demanding fastening applications\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides baseline corrosion resistance for general indoor and sheltered outdoor use\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank suitable for through-bolt and clamped joint connections\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC thread size for broad compatibility with standard 1\/2-inch hardware\u003c\/li\u003e\n  \u003cli\u003eMeets ASTM A354 BD standard for alloy steel bolts and studs\u003c\/li\u003e\n  \u003cli\u003eSold in packs of 10 units per package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/2-13 UNC hex head cap screw suitable for use with any nut, tapped hole, or threaded insert conforming to the 1\/2-13 Unified National Coarse thread specification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed using the correct 3\/4-inch hex drive socket or wrench sized for a standard 1\/2-inch hex head cap screw.
