Measuring 7\/16-20 thread size at 3 inches in length under the head, this fastener features partial threading and a proprietary Bowma-Guard finish for enhanced corrosion resistance. The inch-system sizing and fine-thread pitch make it well suited for joints requiring precise torque control and strong clamping force. Mechanical contractors, millwrights, and industrial maintenance technicians are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in high-load bolted connections across a range of industries including heavy equipment, agricultural machinery, hydraulic systems, and structural fabrication. The 7\/16-20 fine thread pitch is commonly found in applications where vibration resistance and precise preload are critical. Partial threading allows the unthreaded shank to bear shear loads within the joint, which is a standard requirement in many structural and mechanical fastening specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 9 steel construction for superior tensile strength compared to Grade 5 and Grade 8 fasteners\u003c\/li\u003e\n  \u003cli\u003eBowma-Guard finish provides corrosion protection for demanding service environments\u003c\/li\u003e\n  \u003cli\u003e7\/16-20 fine thread pitch for high-torque, vibration-resistant clamping\u003c\/li\u003e\n  \u003cli\u003ePartial threading allows the shank to carry shear loads at the joint interface\u003c\/li\u003e\n  \u003cli\u003e3-inch length under head suits deep-reach fastening in thick assemblies\u003c\/li\u003e\n  \u003cli\u003eInch measurement system; UNSPSC Code 31161501 for procurement classification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit fastener for bolted assemblies requiring a 7\/16-20 fine-thread, Grade 9 hex head cap screw with partial threading and a protective finish.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified mechanics or millwrights familiar with torque specifications for Grade 9 fasteners. Use a calibrated torque wrench and consult the equipment manufacturer's torque table for the correct preload value before tightening. Ensure mating threads are clean, undamaged, and free of debris prior to assembly. Do not substitute a coarse-thread fastener in a fine-thread application, as this will compromise joint integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull or Partial Threading\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: 9\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Bowma-Guard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 5.38 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: BOWMP36387\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BOWMALLOY","offers":[{"title":"Default Title","offer_id":51993281790258,"sku":"BOWMP36387","price":50.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/68d0297ccfd8302a82613404d24c914a_b6f3d3a5-efac-4be1-8dae-212688c70ee3.jpg?v=1789991024","url":"https:\/\/voomisupply.com\/products\/bowmalloy-bowmp36387-hex-head-cap-screw-7-16-20-x-3-in","provider":"Voomi Supply","version":"1.0","type":"link"}
