It features partial threading and a zinc yellow dichromate finish, which provides corrosion resistance in demanding service environments. Manufactured to ASME B18.2.1 dimensional standards, this fastener is suited for high-strength bolted connections in mechanical, industrial, and structural assemblies. Grade 8 designation indicates a minimum tensile strength appropriate for heavy-duty clamping loads, making it a common choice for equipment fabrication, machinery mounting, and structural steel work.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used across a wide range of trade and industrial applications where high-clamping-force fasteners are required. Typical install scenarios include mechanical equipment mounting, HVAC structural framing, pump and motor bases, and general fabrication work. The partial threading allows the unthreaded shank to act as a locating feature in clearance holes, which is useful in shear-loaded connections. This fastener is sold individually per package with a minimum order quantity of 10 pieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile strength in demanding bolted joints\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 UNC thread form per standard inch thread specification\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank for use in shear or locating applications\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish provides corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standards\u003c\/li\u003e\n  \u003cli\u003e4-1\/2 inch length under head accommodates thick material stacks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series hex head cap screw for use in any application requiring a 5\/8-11 UNC threaded fastener with a 4-1\/2 inch length under head and Grade 8 strength rating.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or tradesperson using appropriate hand or power tools rated for 5\/8-inch drive. Always confirm the mating nut or tapped hole uses the matching 5\/8-11 UNC thread specification before assembly. Apply a calibrated torque wrench to reach the fastener manufacturer or equipment OEM recommended clamp load — do not rely on feel alone for Grade 8 fasteners. De-energize and lock out any equipment before replacing or installing fasteners in live mechanical assemblies.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 4-1\/2 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\u003eFinish\u003c\/strong\u003e: Zinc Yellow Dichromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensional Standard\u003c\/strong\u003e: ASME B18.2.1\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: 1 piece\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: D39158\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51710271947058,"sku":"D39158","price":31.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/da57a92664b7730e23f0e2364f872cf3.jpg?v=1788465042","url":"https:\/\/voomisupply.com\/products\/value-collection-d39158-hex-head-cap-screw-5-8-11-x-4-5-in","provider":"Voomi Supply","version":"1.0","type":"link"}
