It is partially threaded and finished with a clear zinc chromate coating for corrosion resistance. This fastener is used in heavy-duty mechanical and structural assemblies where high-strength bolting is required. Millwrights, industrial maintenance technicians, and mechanical contractors typically specify Grade 9 fasteners for demanding load and torque applications where lower-grade hardware is not acceptable.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for industrial and commercial mechanical assemblies, heavy equipment maintenance, structural steel connections, and similar high-load bolted joints. The partial threading design is appropriate for applications requiring a smooth shank section to bear shear loads or provide a precise clamping length. Packaged in quantities of 10 per package, this fastener is practical for both single-use repairs and multi-fastener jobs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 9 steel construction for high tensile strength in demanding applications\u003c\/li\u003e\n  \u003cli\u003e7\/8-9 UNC thread size for compatibility with standard inch-series nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003e3-inch length under head accommodates thicker joint stacks and structural members\u003c\/li\u003e\n  \u003cli\u003ePartial threading provides a smooth shank for shear-bearing and precise clamping\u003c\/li\u003e\n  \u003cli\u003eClear zinc chromate finish provides baseline corrosion protection in moderate environments\u003c\/li\u003e\n  \u003cli\u003eSold in 10-piece packages for efficient job-site use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 7\/8-9 UNC inch-series hex nuts, flat washers, and lock washers in heavy-duty bolted joint assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified millwright, mechanic, or maintenance technician following applicable torque specifications for Grade 9 fasteners and the equipment manufacturer's service documentation. Always use a calibrated torque wrench and the correct 7\/8-inch hex socket when tightening. Inspect mating threads in nuts or tapped holes for damage or contamination before assembly. Do not use impact tools without verifying that final torque is confirmed with a calibrated torque wrench.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/8-9 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 9\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Clear Zinc Chromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement System\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: BOWMALLOY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: BOW36198\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BOWMALLOY","offers":[{"title":"Default Title","offer_id":52106208674098,"sku":"BOW36198","price":99.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7c78b0f9e6c3bbf240f3720a749fdb98_5ee58a1d-5a14-4a79-bd0e-2a329c638613.jpg?v=1790073301","url":"https:\/\/voomisupply.com\/products\/bowmalloy-bow36198-hex-head-cap-screw-7-8-9x3-grade-9","provider":"Voomi Supply","version":"1.0","type":"link"}
