It features partial threading and a zinc-plated finish that provides a baseline level of corrosion resistance for general fastening applications. Grade 8 is a high-strength designation, making this fastener appropriate for mechanically demanding joints where a standard Grade 5 would be insufficient. The zinc plating helps resist oxidation in dry and mildly humid environments. This screw ships in a package quantity of 10 and is sold in multiples of 1.\u003c\/p\u003e\n\u003cp\u003eThis hex cap screw is suited for use in mechanical assemblies, equipment mounting, structural brackets, and general maintenance across HVAC, plumbing, electrical, and industrial trade applications. The 3\/8-16 UNC thread is one of the most common coarse-thread sizes in North American trade work, meaning compatible nuts, threaded inserts, and tapped holes are widely available. Partial threading allows for a grip length on unthreaded shaft sections, which is preferred in applications where clamping force and shear resistance are priorities over full thread engagement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 high-strength steel construction for demanding mechanical joints\u003c\/li\u003e\n  \u003cli\u003e3\/8-16 UNC coarse thread — widely compatible with standard nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003e2-1\/2-inch length under head with partial threading for shear-load applications\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish for baseline corrosion and oxidation resistance\u003c\/li\u003e\n  \u003cli\u003ePackaged in quantities of 10 for bench stock and field service use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with any standard 3\/8-16 UNC hex nut, flat washer, lock washer, or tapped hole conforming to Unified National Coarse thread standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a standard hex wrench, socket, or box-end wrench sized for a 3\/8-inch hex cap screw head. Always de-energize equipment and relieve any system pressure before fastening or removing hardware in live assemblies. Do not exceed the torque specifications listed by the equipment manufacturer for the application. Grade 8 fasteners should not be substituted with lower-grade hardware when replacing in a Grade 8-specified joint.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2-1\/2 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: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Zinc-Plated\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  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 pounds\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: 86853421\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689250160946,"sku":"86853421","price":29.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/92e259dd2ef0831486b6fdd727425be2.jpg?v=1788256378","url":"https:\/\/voomisupply.com\/products\/value-collection-86853421-hex-cap-screw-3-8-16-x-2-1-2-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
