Sized at 3\/4-10 UNC with a 4-inch length under head, this fastener is partially threaded and carries a zinc-plated finish for basic corrosion resistance. Meeting ASTM A354 BD standards, it delivers the tensile and proof load requirements expected in demanding bolted connections. Maintenance technicians, millwrights, pipefitters, and mechanical contractors routinely specify Grade 8 hardware when joint integrity and clamp load retention are critical.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for use in general industrial machinery, structural steel connections, equipment mounting, and mechanical assemblies where UNC thread engagement and high-strength fastener performance are required. The partial thread design concentrates grip length in the shank, making it appropriate for applications where the fastener passes through clearance holes before engaging a nut or tapped bore. Sold in a package quantity of 5.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction meeting ASTM A354 BD for high tensile and proof load performance\u003c\/li\u003e\n  \u003cli\u003e3\/4-10 UNC thread size with 4-inch length under head\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides a longer grip area for through-bolt applications\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish offers basic corrosion protection in indoor and sheltered environments\u003c\/li\u003e\n  \u003cli\u003eInch measurement system with standard UNC thread form for broad nut and tap compatibility\u003c\/li\u003e\n  \u003cli\u003ePackaged in quantities of 5 with a minimum order quantity of 1 package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 3\/4-10 UNC nuts, washers, and tapped bores conforming to inch-series thread standards in industrial, mechanical, and structural fastening applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified millwright, pipefitter, or mechanical technician familiar with high-strength fastener torque procedures. Always degrease or lubricate mating threads consistently to achieve accurate clamp load from applied torque, and refer to applicable engineering or code specifications for the required torque value for this bolt size and grade. Inspect the hex head and thread condition before installation and discard any fasteners showing corrosion, galling, or deformation. De-energize, depressurize, or otherwise isolate the equipment or structure before disassembling any bolted 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\/4-10 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 4 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: 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\u003eThread Standard\u003c\/strong\u003e: UNC (Inch Series)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard \/ Certification\u003c\/strong\u003e: ASTM A354 BD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5 pieces\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: MPKP44139\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51703771824434,"sku":"MPKP44139","price":38.59,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/193f8229be9d50d2972de087597cb063.jpg?v=1788418574","url":"https:\/\/voomisupply.com\/products\/value-collection-mpkp44139-3-4-10x4-gr8-hex-cap-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
