This screw features a 1-8 UNC thread size, a 3.5-inch length under head, and a 0.75-inch hex drive. It is manufactured from alloy steel with a black oxide coating, which provides moderate corrosion resistance and reduces light reflection in service environments. The partially threaded shank allows for controlled clamping force and precise load distribution. Machinists, millwrights, and maintenance technicians commonly install this fastener in high-load or tight-clearance applications where a hex key drive is required.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for use in industrial machinery, fabricated steel structures, jigs, dies, and equipment frames where a recessed drive fastener is preferred over a hex head. The 1-8 UNC coarse thread pitch provides good resistance to loosening under vibration. The partially threaded design is appropriate for through-bolt and blind-hole installations requiring a smooth shank section for alignment or load transfer. A standard hex key or T-handle hex driver in the 0.75-inch drive size is used for installation and removal.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-8 UNC coarse thread for reliable engagement in standard tapped holes\u003c\/li\u003e\n  \u003cli\u003e3.5-inch length under head with partial threading for shank-to-hole alignment\u003c\/li\u003e\n  \u003cli\u003e0.75-inch hex socket drive for use with standard hex keys or T-handle drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction rated to ASTM A574 for high tensile strength\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and low-glare surface\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and IFI 124 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard fastener for applications requiring a 1-8 UNC partially threaded hex socket cap screw in alloy steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed using a 0.75-inch hex key or socket driver. Verify that the mating tapped hole meets the 1-8 UNC thread specification and is free of debris before installation. Apply thread lubricant or thread-locking compound as required by the assembly specification. Follow torque values specified in the engineering documentation for the host assembly, as no torque value is provided with this fastener alone.\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: 3.5 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: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\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: 1.068 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: 015537BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51706667204914,"sku":"015537BR","price":19.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d45b8296ff8720356123861e59477c82.jpg?v=1788435964","url":"https:\/\/voomisupply.com\/products\/value-collection-015537br-hex-socket-cap-screw-1-8-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
