This fastener measures 5\/8-18 thread size with a 2-inch length under head, machined to a Unified National Fine (UNF) thread standard. Constructed from Grade 8 steel in an uncoated finish, it delivers superior tensile and proof load strength compared to lower-grade fasteners. It is manufactured to ASME B18.2.1 and SAE J429 standards, ensuring consistent dimensional accuracy and mechanical performance across the lot.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for heavy-duty bolted connections where fine-thread engagement and high clamp load are required. Grade 8 fasteners are commonly specified in automotive, agricultural equipment, heavy machinery, and structural fabrication work where vibration resistance and joint integrity are critical. Fully threaded construction allows maximum thread engagement along the entire shank length, making it well suited for shorter-grip applications and through-bolt configurations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction meets SAE J429 mechanical property requirements for high-strength fastening\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank provides maximum thread engagement for the entire 2-inch length under head\u003c\/li\u003e\n  \u003cli\u003e5\/8-18 UNF thread form offers finer pitch than coarse-thread equivalents, improving vibration resistance\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for use with customer-applied coatings or in dry indoor assemblies\u003c\/li\u003e\n  \u003cli\u003eManufactured to ASME B18.2.1 dimensional standards for consistent hex geometry and bearing surface\u003c\/li\u003e\n  \u003cli\u003eSold in a package quantity of 25 pieces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/8-18 UNF hex head cap screw for use in any application requiring an inch-system, fine-thread Grade 8 fastener with a 2-inch length under head and full thread engagement.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or tradesperson using the appropriate hex socket or open-end wrench sized for a 5\/8-inch hex fastener. Fastener torque should be determined by the equipment manufacturer's specifications or applicable engineering standards for Grade 8 hardware. Verify thread cleanliness and inspect for damage before installation.
