Measuring 9\/16-12 thread size with a 3-inch length under head, this fastener features partial threading and a clear zinc chromate finish for corrosion resistance. Grade 9 alloy steel delivers tensile strength above standard Grade 5 and Grade 8 fasteners, making it a go-to choice where elevated load ratings and vibration resistance are required. Electricians, HVAC installers, plumbers, and mechanical contractors reach for Grade 9 hex cap screws when specifications call for maximum clamp force in structural or equipment-mounting connections.\u003c\/p\u003e\n\u003cp\u003eThis fastener is suited for heavy-duty mechanical assemblies, equipment mounting, structural steel connections, and industrial machinery installations. The partial threading allows for a clean shank section in the grip area, which improves shear strength and prevents thread galling against mating materials. The clear zinc chromate coating provides a base level of corrosion protection appropriate for indoor and sheltered outdoor applications. Sold in a package quantity of 10 with a minimum order quantity of 1 package.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 9 alloy steel construction for superior tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003e9\/16-12 UNC thread size with 3-inch length under head\u003c\/li\u003e\n  \u003cli\u003ePartial threading for improved shear strength in the grip zone\u003c\/li\u003e\n  \u003cli\u003eClear zinc chromate finish provides corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eInch measurement system, standard UNC thread form\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 10 per pack\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series UNC hex head cap screw for use in any application requiring a 9\/16-12 thread pattern with a 3-inch grip length and Grade 9 alloy steel strength rating.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified mechanical or trade personnel following applicable torque specifications from engineering drawings or recognized fastener standards such as those published by ASME or SAE for Grade 9 fasteners. Always ensure mating threads are clean and free of debris before installation. Do not mix metric and inch fasteners in the same assembly. Use appropriate hand tools or calibrated torque wrenches to achieve proper clamp load without overtorquing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 9\/16-12 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\u003eMaterial\u003c\/strong\u003e: Alloy 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 Coating\u003c\/strong\u003e: Clear Zinc Chromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\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\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: 36137\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BOWMALLOY","offers":[{"title":"Default Title","offer_id":52069411225906,"sku":"36137","price":46.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6e301aea3abd9a649f340e2f28c3cb8e_fa49abaa-24e2-471a-888f-c7300130d361.jpg?v=1790047747","url":"https:\/\/voomisupply.com\/products\/bowmalloy-36137-hex-head-cap-screw-9-16-12-x-3-in-grade-9","provider":"Voomi Supply","version":"1.0","type":"link"}
