Manufactured from Grade 8 steel with a zinc-plated finish, this fastener delivers superior tensile strength and corrosion resistance compared to lower-grade alternatives. The partially threaded shank follows UNC thread standards and meets ASTM A354 BD specification, making it suitable for structural and heavy-duty mechanical assemblies. Each package contains 50 screws. Licensed trades professionals and maintenance technicians use this hardware in industrial equipment, structural steel connections, and heavy machinery where high-grade fasteners are required by code or engineering specification.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for applications demanding Grade 8 fastener performance, including equipment mounting, structural assemblies, and mechanical sub-systems found in commercial and industrial settings. The zinc-plated finish provides a base level of corrosion protection appropriate for indoor and moderately controlled environments. The 5\/16-18 UNC thread pattern is a widely used coarse-thread standard, compatible with standard 5\/16-18 hex nuts, lock nuts, and threaded plate inserts. Plumbers, HVAC technicians, electricians, and general mechanical contractors routinely use Grade 8 hardware when connecting flanges, brackets, equipment rails, and access panels where standard hardware-grade fasteners are insufficient.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction meets ASTM A354 BD specification for high-strength fastening\u003c\/li\u003e\n  \u003cli\u003e5\/16-18 UNC coarse-thread pattern for broad compatibility with standard hardware\u003c\/li\u003e\n  \u003cli\u003e3-inch length under head with partially threaded shank for clamping grip on thick stock\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides corrosion resistance in indoor and controlled environments\u003c\/li\u003e\n  \u003cli\u003ePackaged in a 50-count quantity for job-site and shop use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 5\/16-18 UNC hex nuts, flat washers, lock washers, and threaded inserts.

Always consult the equipment manufacturer torque specification or applicable engineering standard before final tightening. Do not mix Grade 8 fasteners with lower-grade nuts or threaded inserts, as the mismatch can result in thread stripping or joint failure. Inspect threads for damage before installation and replace any fastener showing deformation or corrosion.\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: 3 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 Coating\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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 50 pieces\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: KP44029\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693002064178,"sku":"KP44029","price":45.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ded0fbb90d6b141ca708decf90bc2ac8.jpg?v=1788306057","url":"https:\/\/voomisupply.com\/products\/value-collection-kp44029-5-16-18-x-3-in-grade-8-cap-screw-50pk","provider":"Voomi Supply","version":"1.0","type":"link"}
