Measuring 5\/8-11 thread size with a 2-1\/2 inch length under head, this partially threaded fastener meets ASTM A354 BD standards for mechanical performance. A zinc-plated finish provides corrosion resistance suitable for general service environments. Sold in a package of 25, this screw follows Unified National Coarse (UNC) thread standards and is intended for use by mechanics, millwrights, pipefitters, and general trade professionals requiring reliable, code-recognized fasteners.\u003c\/p\u003e\u003cp\u003eThis hex head cap screw is suited for structural and mechanical assembly work across residential and commercial applications. The 5\/8-11 UNC thread is a common size in heavy-duty equipment mounting, pipe support fabrication, HVAC equipment bases, electrical panel and conduit support structures, and general mechanical installations. The partially threaded shank provides a grip length that improves clamping force in through-bolted connections. The Grade 8 rating makes it appropriate where higher proof load and tensile strength are required compared to Grade 5 or Grade 2 fasteners.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 8 steel construction meets ASTM A354 BD for high-strength fastening requirements\u003c\/li\u003e\n\u003cli\u003e5\/8-11 UNC thread size with 2-1\/2 inch length under head for versatile fitment\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank provides improved clamping in through-bolted assemblies\u003c\/li\u003e\n\u003cli\u003eZinc-plated finish for corrosion resistance in general service environments\u003c\/li\u003e\n\u003cli\u003eSold in a 25-piece package to support job-site and shop inventory needs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 5\/8-11 UNC Grade 8 hex head cap screw suitable for general mechanical and structural fastening applications where ASTM A354 BD compliance is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified mechanic or trade professional using an appropriately sized hex or socket wrench.
