Measuring 1-14 thread size by 3 inches under head, this partially threaded fastener meets ASME B18.2.1 and SAE J429 standards, confirming its suitability for demanding structural and mechanical assemblies. The zinc yellow dichromate finish provides a layer of corrosion resistance while supporting identification of the Grade 8 rating. It is threaded to the UNF standard and is installed by machinists, millwrights, equipment mechanics, and maintenance technicians working on heavy-duty machinery and structural connections.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for industrial, agricultural, construction, and heavy equipment applications where high tensile strength and precise UNF thread engagement are required. Partial threading allows for improved load-bearing performance in through-bolt and clamped-joint configurations. The 3-inch under-head length accommodates moderate material stack heights where a fully threaded shank would not be appropriate. It ships with a minimum order quantity of 10 units per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction meets SAE J429 for high tensile and proof load requirements\u003c\/li\u003e\n  \u003cli\u003eASME B18.2.1 compliant hex head geometry ensures compatibility with standard drive tooling\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank improves shear resistance and clamping force in bolted joints\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish provides corrosion resistance and Grade 8 visual identification\u003c\/li\u003e\n  \u003cli\u003eUNF thread standard offers fine-pitch engagement for precise torque control\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style and replacement fastener for applications requiring a 1-14 UNF, 3-inch under-head, Grade 8 hex cap screw per ASME B18.2.1 and SAE J429 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or technician familiar with high-strength fastener procedures. Always consult the equipment manufacturer torque specification table for the joint material and fastener grade before tightening. Clean and inspect mating threads before assembly to avoid galling or cross-threading. Do not reuse fasteners that show signs of thread deformation, corrosion, or prior overtorque.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-14\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\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 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc Yellow Dichromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B18.2.1, SAE J429\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: D39517\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690741563698,"sku":"D39517","price":137.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/59a196779e54ea92b016f4c6d9f97854.jpg?v=1788274750","url":"https:\/\/voomisupply.com\/products\/value-collection-d39517-hex-head-cap-screw-1-14-x-3-in","provider":"Voomi Supply","version":"1.0","type":"link"}
