It features a 1-8 UNC thread size with 8 inches of length under the head and is partially threaded to allow for clamping force across unthreaded shank sections. The 5\/8 inch internal hex drive accepts a standard Allen or hex key for installation. Constructed from alloy steel with a black oxide coating, it meets ASTM A574 requirements, making it suited for demanding load-bearing applications where tensile strength and corrosion resistance are priorities.\u003c\/p\u003e\u003cp\u003eThis cap screw is used in general industrial, machining, and maintenance applications where a recessed drive head is required to sit flush or below the surface of the mated component. Partial threading is common in applications where bolt stretch and clamping load distribution matter, such as fixture plates, machine frames, and equipment housings. It is appropriate for use by millwrights, machinists, maintenance technicians, and industrial mechanics working in light to heavy manufacturing environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-8 UNC thread form provides coarse-thread engagement suitable for steel and heavy materials\u003c\/li\u003e\n\u003cli\u003e8 inch length under head accommodates thick stack-ups and deep bolt patterns\u003c\/li\u003e\n\u003cli\u003e5\/8 inch hex socket drive allows high torque input with standard Allen keys or hex sockets\u003c\/li\u003e\n\u003cli\u003ePartial threading preserves an unthreaded shank section for improved shear and clamping load\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASTM A574 for high-strength socket cap screw requirements\u003c\/li\u003e\n\u003cli\u003eBlack oxide coating provides mild corrosion resistance and reduces light reflection in service\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard ASTM A574 hex socket cap screw for use in any application requiring a 1-8 UNC coarse thread, partially threaded configuration with an 8 inch length under head.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed using a 5\/8 inch hex key or Allen socket drive. Ensure mating threads are clean and free of debris before installation. Apply thread lubricant or thread-locking compound as required by the application specification. Torque values should be referenced from applicable engineering standards or equipment manufacturer documentation rather than assumed from fastener size alone.\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: 8 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\/Coating\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: 307250BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721777447218,"sku":"307250BR","price":71.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9b827d4ddcfc95f4c7b7a8ba23c014ea.jpg?v=1788580666","url":"https:\/\/voomisupply.com\/products\/value-collection-307250br-hex-socket-cap-screw-1-8-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
