It features a 3\/8-16 unified coarse thread and a 3.5-inch length under head. Manufactured from Grade 9 alloy steel, this fastener delivers tensile strength well beyond standard Grade 5 or Grade 8 hardware. A clear zinc chromate finish provides corrosion resistance in shop and field environments. Licensed tradespeople, millwrights, and industrial mechanics reach for Grade 9 hardware when load requirements demand maximum performance from a standard hex head profile.\u003c\/p\u003e\n\u003cp\u003eThis cap screw suits heavy-duty bolted connections in manufacturing equipment, agricultural machinery, hydraulic assemblies, and other applications where high-clamp-load and vibration resistance are critical. The 3\/8-16 coarse thread engages quickly and resists cross-threading in field conditions. The partial threading allows the unthreaded shank to act as a precision locating feature or shear-load bearing surface in close-tolerance bores. Sold in packages of 50, the 36064 is well suited for maintenance shops and contractors stocking standard fastener sizes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 9 alloy steel construction for tensile strength exceeding standard Grade 8 hardware\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 unified coarse thread for broad tool and nut compatibility\u003c\/li\u003e\n  \u003cli\u003e3.5-inch length under head accommodates thick stack-ups and deep engagement\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank supports shear loading and close-tolerance locating\u003c\/li\u003e\n  \u003cli\u003eClear zinc chromate finish for corrosion protection in shop and outdoor environments\u003c\/li\u003e\n  \u003cli\u003eInch measurement system for compatibility with standard SAE tooling and hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style and aftermarket replacement hex head cap screw for any application requiring a 3\/8-16 coarse-thread fastener with a 3.5-inch length under head in Grade 9 alloy steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or tradesperson following the torque specifications published by the equipment manufacturer for Grade 9 fasteners. Always use a calibrated torque wrench and apply the correct SAE-grade nut or tapped hole rated for the load. Inspect the mating threads and seating surface for damage before assembly. De-energize and lockout all equipment per OSHA lockout\/tagout procedures before performing fastener replacement on live machinery.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3.5 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: 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\u003eSystem of Measurement\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: 50\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: 36064\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BOWMALLOY","offers":[{"title":"Default Title","offer_id":51972160717106,"sku":"36064","price":108.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a2b35f34640cb79dd166d4807bc475b0_7f9971d0-f327-4160-9835-ff6070201361.jpg?v=1789963598","url":"https:\/\/voomisupply.com\/products\/bowmalloy-36064-hex-head-cap-screw-3-8-16-x-3-5-in-grade-9","provider":"Voomi Supply","version":"1.0","type":"link"}
