It features a 1-8 UNC thread size and a 4.5-inch length under head, with partial threading along the shank. A zinc-plated finish provides baseline corrosion resistance in standard service environments. This fastener meets ASTM A354 BD specifications, making it suitable for structural and mechanical assemblies where verified tensile and proof load requirements apply. Machinists, millwrights, ironworkers, and general contractors commonly install this type of fastener in heavy equipment, structural steel connections, and industrial machinery.\u003c\/p\u003e\n\u003cp\u003eThe KP44170 is suited for inch-system bolted joints requiring a high-strength, partially threaded fastener. The partial thread allows the unthreaded shank to carry shear loads across mating surfaces, which is typical in clevis pins, flanged joints, and structural beam connections. Packaged in quantities of 10, this screw is appropriate for both single-job use and moderate-volume shop stock.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction meets ASTM A354 BD proof load and tensile strength requirements\u003c\/li\u003e\n  \u003cli\u003e1-8 UNC partial threading leaves an unthreaded shank for shear-load applications\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides corrosion resistance for standard indoor and light-duty outdoor use\u003c\/li\u003e\n  \u003cli\u003eInch measurement system with 4.5-inch length under head for deep-reach fastening\u003c\/li\u003e\n  \u003cli\u003eSold in packs of 10 for convenient job-site or shop stocking\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or new-installation fastener for any bolted assembly requiring a 1-8 UNC Grade 8 hex head cap screw with a 4.5-inch length under head and partial threading.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified tradesperson following applicable structural or mechanical codes. Always verify the mating nut thread standard is UNC before assembly. Use a calibrated torque wrench and follow the fastener grade torque specifications provided by the equipment manufacturer or applicable engineering standards. Inspect threads for damage before installation and do not reuse fasteners that show signs of yielding 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: 1-8 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 4.5 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\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASTM A354 BD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement System\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: KP44170\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693420478770,"sku":"KP44170","price":128.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/07295be3c50d87eeb2388320ecb1d361.jpg?v=1788312116","url":"https:\/\/voomisupply.com\/products\/value-collection-kp44170-hex-head-cap-screw-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
