Manufactured from Grade 2 steel with a zinc-plated finish for basic corrosion resistance, this fastener meets ASME B18.2.1 and SAE J429 standards. It weighs 2.59 pounds. The hex drive head accepts standard hex wrenches and impact sockets, making installation straightforward in mechanical, structural, and industrial assembly applications. Partial threading provides a smooth shank section that resists shear loads in bolted connections.\u003c\/p\u003e\u003cp\u003eThis screw is suited for general-purpose fastening in maintenance, fabrication, and light structural work. The 1-1\/8-7 UNC thread form is a coarse-pitch designation common in inch-standard assemblies. The 8-inch length under the head accommodates thicker stack-ups and flanged connections. Trades including millwrights, pipefitters, HVAC installers, and general maintenance technicians regularly stock this size for equipment mounting, ductwork support frames, and mechanical bases.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePartially threaded shank — smooth section handles shear loads in bolted joints\u003c\/li\u003e\n\u003cli\u003eGrade 2 steel construction meets SAE J429 mechanical requirements\u003c\/li\u003e\n\u003cli\u003eZinc-plated finish provides baseline corrosion protection in dry or mildly humid environments\u003c\/li\u003e\n\u003cli\u003eUNC coarse thread form for fast engagement and broad tool compatibility\u003c\/li\u003e\n\u003cli\u003eConforms to ASME B18.2.1 dimensional standard for inch hex cap screws\u003c\/li\u003e\n\u003cli\u003e8-inch under-head length suits thick structural and mechanical stack-ups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard inch-series hex head cap screw for use in any application requiring a 1-1\/8-7 UNC partially threaded fastener per ASME B18.2.1.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed with a properly sized hex wrench or impact socket rated for 1-1\/8-inch drive. Always confirm the mating tapped hole or nut is the same UNC thread standard before assembly. De-energize or lock out any equipment being serviced before fastener installation or removal. Avoid using zinc-plated fasteners in continuously wet or chemically aggressive environments where a higher-grade coating or stainless material would be more appropriate.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-1\/8-7 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 8 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 2\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\u003eStandards\u003c\/strong\u003e: ASME B18.2.1, SAE J429\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.59 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: R52000987\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690887348530,"sku":"R52000987","price":27.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/190494e70233ad13188d24946b6f0697.jpg?v=1788277016","url":"https:\/\/voomisupply.com\/products\/value-collection-r52000987-hex-head-cap-screw-1-1-8-7-x-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
