It features a 1-8 UNC thread size, a 4.5-inch length under head, and a 5\/8-inch hex drive. The fastener is manufactured from alloy steel and finished with a black oxide coating that provides moderate corrosion resistance and reduces light reflection. It conforms to ASTM A574, the standard specification for alloy steel socket-head cap screws. Machinists, millwrights, and maintenance technicians install this type of fastener where high clamp load and a flush or recessed head profile are required.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in heavy equipment, machine bases, die sets, fixtures, and structural brackets where a 1-inch coarse-thread fastener is specified. The partial threading allows the unthreaded shank to provide shear resistance and precise locating in close-tolerance bored holes. The black oxide finish is common in industrial environments where the fastener will be periodically lubricated or where a non-reflective appearance is preferred over a bright finish.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-8 UNC thread form — coarse pitch for fast engagement and resistance to cross-threading in production environments\u003c\/li\u003e\n  \u003cli\u003e4.5-inch length under head accommodates thick structural members and stacked components\u003c\/li\u003e\n  \u003cli\u003ePartial threading allows the shank to function as a locating or shear pin in precision bores\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction provides high tensile and proof-load strength per ASTM A574\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating reduces surface corrosion and minimizes galling during installation\u003c\/li\u003e\n  \u003cli\u003e5\/8-inch hex drive accepts standard hex keys and socket drivers at that size\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 application requiring a 1-8 UNC partially threaded hex socket cap screw conforming to ASTM A574.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, millwrights, or maintenance technicians using a 5\/8-inch hex key or socket driver. Always clean and inspect the tapped hole before installation, and apply an appropriate thread lubricant or anti-seize compound to achieve consistent clamp load. Power down or de-energize any equipment before accessing fastened assemblies. Do not substitute this fastener in applications specifying a different grade, thread form, or head style without verifying load requirements.\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\u003eDrive Type\u003c\/strong\u003e: Hex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\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: 307242BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51706545439026,"sku":"307242BR","price":62.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/06ac76c3785fa4ea3a74db686175c87a.jpg?v=1788435320","url":"https:\/\/voomisupply.com\/products\/value-collection-307242br-hex-socket-cap-screw-1-8-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
