Manufactured from Grade 8 steel with a zinc-plated finish, this fastener meets ASTM A354 BD standards, making it suitable for load-bearing connections where tensile strength and corrosion resistance are required. The 5\/16-18 UNC thread profile ensures compatibility with standard inch-series tapped holes and nuts. Sold in a package of 50, this screw is a practical stocking item for maintenance shops, contractors, and field service professionals who need reliable high-strength fasteners on hand.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for use in general industrial equipment, machinery frames, brackets, and structural connections where Grade 8 strength is specified. The zinc-plated finish provides a base level of corrosion protection appropriate for indoor and light-duty outdoor applications. The fully threaded 1 inch length under head allows maximum thread engagement across the full grip length, which is useful when fastening thinner materials or when thread engagement depth is critical to the joint design.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction meets ASTM A354 BD for high-strength bolted joint requirements\u003c\/li\u003e\n  \u003cli\u003eFully threaded 5\/16-18 UNC profile maximizes thread engagement across the full shank length\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides basic corrosion resistance for general service environments\u003c\/li\u003e\n  \u003cli\u003e1 inch length under head suits a wide range of fastening depths in thin to medium material stacks\u003c\/li\u003e\n  \u003cli\u003eSold in a quantity of 50 per package, suitable for stocking and bulk service work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 5\/16-18 UNC inch-series tapped holes, nuts, and threaded inserts in applications where Grade 8 or equivalent high-strength fasteners are specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by mechanics, millwrights, or maintenance technicians using a standard hex wrench or socket drive. Always verify that the mating nut or tapped hole is rated for Grade 8 loading before final torque. De-energize and lock out any equipment before replacing fasteners in live machinery. Do not mix Grade 8 fasteners with lower-grade nuts or threaded components, as this can compromise joint integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1 inch\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: Fully 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: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASTM A354 BD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 50\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: MPKP44021\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721288122674,"sku":"MPKP44021","price":22.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b196023c0ed18ba32427909b3370135b.jpg?v=1788575902","url":"https:\/\/voomisupply.com\/products\/value-collection-mpkp44021-hex-cap-screw-5-16-18-x-1-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
