The partially threaded shank provides a bearing surface under the head for applications requiring a clamp load without full thread engagement along the grip length. The UNC (Unified National Coarse) thread standard makes this fastener compatible with standard inch-series tapped holes. Hot-dipped galvanizing provides a durable zinc coating that resists corrosion in outdoor, wet, and moderately harsh environments. Grade 5 alloy meets SAE medium-strength requirements, making it suitable for structural and mechanical fastening in general trade and construction applications. Installation is typically performed by electricians, plumbers, HVAC technicians, and general contractors wherever a heavy-hex fastener with corrosion protection is required.\u003c\/p\u003e\n\u003cp\u003eThis hex head cap screw is used in residential and commercial construction, mechanical equipment mounting, structural connections, and utility infrastructure where inch-series fasteners with corrosion-resistant finishes are specified. The 4-inch length under head accommodates thicker material stacks. The hot-dipped galvanized coating makes this screw appropriate for exterior use, treated lumber contact, and other environments where bare steel would corrode prematurely. It is sold individually and is suitable for low-volume service and repair work as well as single-unit replacement needs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 5 steel construction meets SAE medium-strength tensile requirements\u003c\/li\u003e\n  \u003cli\u003eHot-dipped galvanized finish provides heavy zinc coating for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank allows a defined grip length for clamping applications\u003c\/li\u003e\n  \u003cli\u003eUNC thread standard for compatibility with standard inch-series nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003e1-8 x 4 inch size suitable for heavy-duty structural and mechanical fastening\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard UNC inch-series hex nuts, flat washers, and lock washers in 1-8 thread size.

Verify that the mating nut or tapped hole uses a UNC thread form before installation to avoid cross-threading. When fastening into treated lumber or exterior assemblies, ensure the galvanized coating is not damaged during installation, as exposed steel will corrode. Follow applicable building codes and torque specifications provided by the equipment manufacturer or structural engineer of record.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 4 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 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Hot-Dipped Galvanized\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.13 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: HCI51000400G-010BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691194057010,"sku":"HCI51000400G-010BX","price":21.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/234cf9418a4cfe4eb69b1f702e76554d.jpg?v=1788281281","url":"https:\/\/voomisupply.com\/products\/value-collection-hci51000400g-010bx-hex-cap-screw-1-8x4-grade-5","provider":"Voomi Supply","version":"1.0","type":"link"}
