Grade 8 is the highest common SAE fastener grade, offering tensile strength suitable for heavy structural, mechanical, and industrial applications. The screw features partial threading along the shank, which provides a smooth bearing surface between mating parts and resists lateral shear loads better than a fully threaded fastener. It conforms to ASME B18.2.1 and SAE J429, the governing standards for inch-series hex head screws and mechanical property requirements. This fastener is installed by maintenance technicians, millwrights, mechanical contractors, and heavy equipment service professionals.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in applications requiring high-strength fastening under significant load or vibration, including heavy equipment assemblies, structural steel connections, machinery mounts, and industrial fabrication. The 7\/8-9 UNC thread is a coarse-thread designation common in structural and general mechanical applications where rapid assembly and resistance to cross-threading are priorities. The partial thread shank suits through-bolt configurations where precise shank-to-hole fit matters. Sold in packages of 25, this fastener suits job-lot procurement for maintenance shops, contractors, and fabricators.\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\u003e7\/8-9 UNC coarse thread for reliable engagement in structural and mechanical assemblies\u003c\/li\u003e\n  \u003cli\u003e4-inch length measured under the head, partially threaded shank for shear-load resistance\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — suitable for applications where a specific coating or plating will be applied, or where coatings are not required\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standards for hex head cap screws\u003c\/li\u003e\n  \u003cli\u003eSold in a package quantity of 25 for job-lot and shop stocking use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series hex head cap screw for use in any application requiring a 7\/8-9 UNC thread pattern with a 4-inch grip length and Grade 8 mechanical properties.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed millwrights, mechanical contractors, or qualified maintenance technicians using standard hex wrenches or impact tooling sized for 7\/8-9 fasteners.
