Built from alloy steel with a black oxide finish, this fastener delivers corrosion resistance and a clean appearance suited to demanding environments. The screw features a 7\/8-14 UNF thread size, a 6-inch length under head, and accepts a 3\/4-inch hex drive. Partial threading along the shank provides precise clamping force and is standard for this length and diameter class. Machinists, millwrights, and maintenance technicians are the primary installers of fasteners in this category.\u003c\/p\u003e\u003cp\u003eThis socket cap screw is used in heavy equipment assembly, fixture fabrication, tooling setups, and general industrial machinery where a high-strength, recessed-drive fastener is required. The fine 14 TPI thread pitch makes it well suited for applications requiring precise torque control or use in thin-walled or tapped-hole assemblies where thread engagement accuracy matters. Its black oxide finish makes it a common choice in applications where surface reflectivity must be minimized or where light oil retention is beneficial for corrosion resistance.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7\/8-14 UNF fine-thread for precise thread engagement and torque control\u003c\/li\u003e\n\u003cli\u003e6-inch length under head with partial threading for optimal clamping\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction for high tensile strength in demanding assemblies\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish provides mild corrosion resistance and low reflectivity\u003c\/li\u003e\n\u003cli\u003e3\/4-inch hex socket drive compatible with standard hex keys and socket drives\u003c\/li\u003e\n\u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM A574 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard hex socket cap screw for use in tapped holes or with nuts conforming to 7\/8-14 UNF thread specifications in industrial and mechanical assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by machinists, millwrights, or maintenance technicians using a calibrated torque wrench and the appropriate 3\/4-inch hex key or socket driver. Ensure mating threads are clean and free of debris before installation. Do not exceed the rated torque for the thread size and material grade. Always de-energize and lock out equipment before servicing fasteners in live machinery per OSHA lockout\/tagout requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/8-14 UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 6 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 and ASTM A574\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 581798BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721792389426,"sku":"581798BR","price":31.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dad0ec9c1cb66d1f039fca475da3c228.jpg?v=1788580932","url":"https:\/\/voomisupply.com\/products\/value-collection-581798br-hex-socket-cap-screw-7-8-14-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
