The screw features a 1-8 UNC thread form and a 5-inch length under head, with partial threading along the shank. Drive engagement is via a 3\/4-inch hex socket, requiring a standard hex key or socket driver. The body is machined from alloy steel and finished with a black oxide coating, which provides moderate corrosion resistance and reduces light reflection in precision environments. This fastener is manufactured to ASME\/ANSI B18.3, ASTM A574, and IFI 124 standards.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in fabrication shops, machine shops, die sets, fixtures, and heavy mechanical assemblies where a socket-drive cap screw is required. The partial thread configuration is appropriate for applications where the unthreaded shank must pass through a clearance hole before engaging a tapped bore. Machinists, millwrights, and maintenance mechanics typically install this fastener in equipment requiring controlled clamp load and clean socket engagement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-8 UNC thread size for coarse-thread engagement in steel and iron tapped holes\u003c\/li\u003e\n  \u003cli\u003e5-inch length under head with partial threading for through-clearance and tapped-bore installations\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch hex socket drive for high-torque tool engagement\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction rated to ASTM A574 high-strength cap screw specification\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for mild corrosion resistance and reduced surface reflectivity\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and IFI 124 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME\/ANSI B18.3 hex socket cap screw suitable for tapped 1-8 UNC bores in steel, cast iron, and compatible alloy assemblies requiring a partially threaded cap screw at 5-inch under-head length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a calibrated torque wrench with a 3\/4-inch hex bit to achieve proper clamp load without yielding the fastener. De-energize and lock out any equipment before fastener service in powered machinery. Verify thread engagement depth in the tapped bore meets minimum requirements per ASME standards before applying full torque. Inspect threads and socket recess for damage before installation.\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: 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 Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 3\/4 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: ASME\/ANSI B18.3, ASTM A574, IFI 124\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.37 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: 015543BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696016654642,"sku":"015543BR","price":22.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8dce03f3c7ab3bf4ce3a69cd424d8fc8.jpg?v=1788339791","url":"https:\/\/voomisupply.com\/products\/value-collection-015543br-hex-socket-cap-screw-1-8-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
