Manufactured from Grade 8 steel with a zinc yellow dichromate finish, this fastener delivers superior tensile strength and corrosion resistance compared to lower-grade alternatives. The 7\/16-20 UNF thread size and 1.5-inch length under head make it well suited for precision-fit bolted connections where fine thread engagement and clamping force are critical. Machinists, millwrights, maintenance technicians, and field mechanics install this type of fastener across a wide range of equipment and fabrication tasks.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in heavy-duty bolted assemblies requiring a fine-thread fastener with high proof load capacity. Typical applications include automotive driveline components, machinery frames, hydraulic system mounting, agricultural equipment, and structural steel connections where Grade 8 strength is specified. The zinc yellow dichromate coating provides a moderate level of corrosion protection appropriate for indoor and sheltered outdoor environments. Compliance with ASME B18.2.1 and SAE J429 standards ensures dimensional accuracy and material performance meet recognized industry requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction provides high tensile and proof load strength for demanding fastening applications\u003c\/li\u003e\n  \u003cli\u003e7\/16-20 UNF fine thread offers increased thread engagement and resistance to loosening under vibration\u003c\/li\u003e\n  \u003cli\u003eFully threaded along the 1.5-inch shank length for maximum thread engagement flexibility\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish provides corrosion resistance and visual identification as a Grade 8 fastener\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.1 dimensional standards and SAE J429 material and mechanical property standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNF hex head cap screw suitable for any application specifying a 7\/16-20 Grade 8 fully threaded fastener per ASME B18.2.1 and SAE J429.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified technician using a properly sized hex socket or open-end wrench. Always confirm the mating thread is 7\/16-20 UNF before installation to avoid cross-threading. Clean and inspect the threaded hole before fastening. Apply torque according to the equipment manufacturer's specification for Grade 8 fasteners of this thread size; do not substitute a lower-grade fastener in a Grade 8 application.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-20 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1.5 inches\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 Coating\u003c\/strong\u003e: Zinc Yellow Dichromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\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\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: D39381\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715374219570,"sku":"D39381","price":31.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/85fcb5d6ea69659f6b36c74d4d47dcfe.jpg?v=1788512959","url":"https:\/\/voomisupply.com\/products\/value-collection-d39381-hex-head-cap-screw-7-16-20-x-1-5-in","provider":"Voomi Supply","version":"1.0","type":"link"}
