Partially threaded and left with a bright, uncoated finish, this fastener is built for high-strength bolted connections in structural, mechanical, and industrial applications. It meets ASME B18.2.1 and SAE J429 standards, confirming dimensional and mechanical property compliance. Sold in a package of 25, it suits job-site and shop use where a reliable supply of heavy-duty inch-series fasteners is needed. Installation requires standard hex tooling and is suited to skilled tradespeople working in fabrication, construction, or maintenance environments.\u003c\/p\u003e\n\u003cp\u003eThis screw is appropriate for heavy-duty fastening tasks where high clamping force and tensile strength are required. The 7\/8-9 coarse thread (UNC) engages efficiently in steel and cast components, making it a common choice for structural steel assembly, equipment mounting, and machine bolting. The partial threading allows the unthreaded shank to bear shear loads in close-tolerance holes, which is typical in structural and mechanical connections. Packaged in quantities of 25, it is well suited for both single-job use and ongoing shop inventory.\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\u003e7\/8-9 UNC coarse thread for reliable engagement in steel and cast materials\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank supports shear-load applications in close-tolerance holes\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — suitable for dry or controlled environments\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.1 and SAE J429 dimensional and mechanical standards\u003c\/li\u003e\n  \u003cli\u003ePackaged in 25-piece quantities for convenient inventory management\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series Grade 8 hex head cap screw for use wherever 7\/8-9 UNC fasteners are specified in structural steel, heavy equipment, and general industrial bolted connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified tradespeople or maintenance personnel familiar with torque requirements for Grade 8 fasteners. Always consult the applicable engineering specification or torque table for the specific joint design — do not rely on general estimates for critical structural connections. Use properly rated hex wrenches, impact sockets, or torque wrenches appropriate for 7\/8-inch drive. Inspect mating threads and bearing surfaces for damage before assembly.\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: 3-1\/4 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\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\u003eFinish \/ Coating\u003c\/strong\u003e: Bright \/ Uncoated\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\u003ePackage Quantity\u003c\/strong\u003e: 25 pieces\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 121810\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51703974953266,"sku":"121810","price":92.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c28eb2d4d9e32575ba55f00249d822d4_e3dbc0e8-3b33-449f-adbc-7e3c219ef369.jpg?v=1788419808","url":"https:\/\/voomisupply.com\/products\/value-collection-121810-hex-cap-screw-7-8-9-grade-8-25-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
