Built to Grade 8 steel specification, this fastener delivers high tensile strength suited for joints subject to significant load and vibration. It carries a 1-8 thread size with a 5-inch length under head, following UNC thread standards and manufactured in conformance with ASME B18.2.1. The uncoated finish makes it a straightforward choice where bare steel is acceptable or where a specific coating will be applied in the field. Machinists, millwrights, and maintenance technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used across a wide range of industrial and trade applications including equipment mounting, structural steel connections, heavy machinery assembly, and general mechanical fastening where Grade 8 strength is required. The partially threaded shank provides a smooth bearing surface in the grip zone, which is critical for shear-loaded joints. Sold in a package quantity of 10 with a minimum order quantity of 1 package, this SKU suits both single-repair needs and small-batch maintenance work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides a clean grip zone for shear-loaded joints\u003c\/li\u003e\n  \u003cli\u003e1-8 UNC thread standard ensures broad nut and tapped-hole compatibility\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional and tolerance standards\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for bare-steel applications or field-applied coatings\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 10 per order\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNC Grade 8 hex head cap screw for use with any 1-8 UNC threaded nut or tapped hole requiring ASME B18.2.1-compliant fasteners.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists, millwrights, or maintenance technicians using standard hex wrenches or impact tools rated for Grade 8 fasteners. Always verify thread engagement depth and grip length before final assembly. Follow applicable torque guidelines from ASME or the equipment manufacturer for Grade 8 fasteners of this thread size. Inspect mating threads for damage before installation to avoid galling or cross-threading.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B18.2.1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage 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: 99223\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722725327154,"sku":"99223","price":91.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1cdf51a6f4c0ab91d4dc696dc50c3ab4.jpg?v=1788595015","url":"https:\/\/voomisupply.com\/products\/value-collection-99223-hex-head-cap-screw-1-8x5-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
