The screw features partial threading along the shank, a unified coarse (UNC) thread standard, and a zinc-plated finish that provides baseline corrosion resistance. It conforms to ASTM A354 Grade BD, a specification covering heavy hex bolts and screws intended for high-load fastening where tensile and proof-load requirements are critical. Tradespeople, maintenance technicians, and mechanical contractors use Grade 8 fasteners when standard hardware-grade screws lack the strength margin required by the application.\u003c\/p\u003e\n\u003cp\u003eThis hex head cap screw is suited for heavy equipment assembly, structural steel connections, machinery mounting, and industrial maintenance work where high-clamping-force fasteners are specified. The partially threaded shank allows the unthreaded portion to bear shear loads more effectively than a fully threaded fastener, making it a common choice in applications where the bolt passes through a clearance hole before engaging a tapped bore or nut. Sold in a package quantity of 10, it is appropriate for both single-repair jobs and small-batch maintenance tasks.\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 tensile strength and proof load requirements\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank improves shear load performance versus fully threaded fasteners\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides corrosion resistance in general-service environments\u003c\/li\u003e\n  \u003cli\u003eUNC thread standard ensures broad compatibility with standard inch-system nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003eHex head drive accepts standard hex wrenches and impact sockets for installation and removal\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 10 per order supports small repairs and maintenance work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a high-strength replacement or new-installation fastener for 1-8 UNC threaded applications requiring Grade 8 tensile ratings and ASTM A354 BD compliance.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or maintenance technician familiar with torque specifications for Grade 8 fasteners at this thread size. Always consult the equipment manufacturer or applicable structural engineering specifications for required torque values before installation. Use a calibrated torque wrench to achieve proper clamp load; do not rely on impact tools alone without a final torque verification step. Inspect mating threads and the bearing surface for damage or contamination before assembly.\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 (1 inch diameter, 8 threads per inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3.5 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: 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: KP44167\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51718203474226,"sku":"KP44167","price":107.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/423aeacc538a7bd72f90c0c7a5ccce19.jpg?v=1788550779","url":"https:\/\/voomisupply.com\/products\/value-collection-kp44167-hex-head-cap-screw-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
