Measuring 4 inches under the head with a 7\/8-9 UNC thread pattern, this cap screw is partially threaded and manufactured from Grade 5 steel with a zinc-plated finish for basic corrosion resistance. It conforms to ASME B18.2.1 dimensional standards, ensuring consistent fit across standard tooling and hardware. Licensed tradespeople, millwrights, pipefitters, and mechanical contractors use this fastener where a reliable medium-strength hex cap screw is required in structural or equipment assembly work.\u003c\/p\u003e\n\u003cp\u003eThis fastener suits a wide range of industrial, commercial, and mechanical assembly scenarios where 7\/8-9 UNC threading is specified. Partial threading keeps the unthreaded shank in the grip length, making it appropriate for bolted joint applications that require a shank to bear shear loads. The zinc finish provides light-duty corrosion protection suitable for indoor or sheltered environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/8-9 UNC thread size with 4-inch length under head\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank for shear-bearing joint applications\u003c\/li\u003e\n  \u003cli\u003eGrade 5 steel construction for medium-strength fastening\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish for basic corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standards\u003c\/li\u003e\n  \u003cli\u003eInch measurement system; standard hex head drive\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNC hex head cap screw per ASME B18.2.1, compatible with any application specifying a 7\/8-9 x 4-inch Grade 5 partially threaded fastener in the inch measurement system.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a standard hex wrench or socket matched to the 7\/8-inch head size. Follow applicable torque specifications from the equipment manufacturer or relevant structural standards for Grade 5 fasteners. Ensure mating threads are clean and free of debris before installation. Do not exceed the rated grade strength by applying torque beyond design limits, and inspect threads for damage before reuse.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/8-9 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 4 inches\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 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensional Standard\u003c\/strong\u003e: ASME B18.2.1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement System\u003c\/strong\u003e: Inch\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: D30165-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695796977970,"sku":"D30165-4","price":48.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/954e4e70db7b13befcb7e791b93149c8.jpg?v=1788338294","url":"https:\/\/voomisupply.com\/products\/value-collection-d30165-4-hex-head-cap-screw-7-8-9x4","provider":"Voomi Supply","version":"1.0","type":"link"}
