It features a 1-8 UNC thread size with a 4-inch length under the head and a 5\/8-inch hex drive. The screw is partially threaded, which provides a smooth shank section for shear-load applications and improved clamping force. Manufactured from alloy steel with a black oxide finish, it meets ASTM A574 requirements for mechanical properties. Licensed trades and maintenance professionals use this fastener where high tensile strength and a low-profile socket-head design are required.\u003c\/p\u003e\u003cp\u003eThis cap screw is suited for use in machinery, equipment frames, tooling fixtures, and structural mechanical assemblies where a flush or recessed fastener head is necessary. The 1-8 UNC coarse thread is appropriate for general-purpose fastening into steel, cast iron, and aluminum components. The partial thread configuration is typically selected when bolt grip length and shear resistance are priorities over full thread engagement.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-8 UNC coarse thread for reliable engagement in standard tapped holes\u003c\/li\u003e\n\u003cli\u003e4-inch length under head with partial threading for improved shear performance\u003c\/li\u003e\n\u003cli\u003e5\/8-inch hex socket drive compatible with standard Allen keys and hex bit drivers\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASTM A574 mechanical strength requirements\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces light reflection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard-spec fastener for assemblies requiring a 1-8 UNC partially threaded hex socket cap screw conforming to ASTM A574.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by qualified mechanical, industrial, or maintenance trade professionals. Always verify the tapped hole thread spec and depth before installation. Use the correct 5\/8-inch hex key or socket-head driver and apply torque per the assembly engineered specification — do not over-torque alloy socket cap screws in soft base materials. Confirm the fastener is fully seated and that the partial thread shank is positioned within the grip zone of the joint.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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 inches\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: 5\/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: 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\u003eWeight\u003c\/strong\u003e: 0.05 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: 307240BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701889925426,"sku":"307240BR","price":41.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c3d4393290d1151337a0e6cc1706718c_eebb25b5-637e-4c31-8320-5eb755a16c17.jpg?v=1788406565","url":"https:\/\/voomisupply.com\/products\/value-collection-307240br-hex-socket-caprew-1-8-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
