It features a 5\/8-18 UNF thread form, which is a fine-thread pitch suited for applications demanding precise torque control and resistance to loosening under vibration. The screw measures 1 inch in length under the head and is fully threaded along that length. It is manufactured from alloy steel with a black oxide finish, providing a combination of tensile strength and moderate corrosion resistance. Machinists, millwrights, and maintenance technicians install these fasteners regularly in mechanical assemblies, fixtures, and equipment frames.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used wherever a recessed hex drive is preferred over an external hex head, such as in confined spaces or flush-mount applications. The 5\/8-18 UNF fine thread is commonly found in precision mechanical assemblies, hydraulic components, and machine tool fixtures. The 1\/2 inch hex drive size requires a standard 1\/2 inch hex key or Allen-style driver. This screw is appropriate for both original equipment assembly and maintenance replacement work in industrial, commercial, and trade settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-18 UNF fine thread for precise engagement and vibration resistance\u003c\/li\u003e\n  \u003cli\u003eFully threaded 1 inch length under head maximizes thread engagement in shallow assemblies\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction provides high tensile and shear strength\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish offers moderate corrosion resistance and reduces light reflection\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch hex socket drive for use with standard hex keys or Allen drivers\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM A574 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard hex socket cap screw conforming to ASME\/ANSI B18.3 and ASTM A574, suitable for use in any mechanical assembly or fixture requiring a 5\/8-18 UNF fully threaded socket head cap screw.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, millwrights, or maintenance technicians using a 1\/2 inch hex key or Allen-style driver. Ensure mating threads are clean and free of debris before installation. Power down or de-energize any associated equipment before fastener replacement work begins. Do not exceed the rated torque range for the material being clamped, and verify thread engagement depth meets the requirements of the assembly design.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-18 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull or Partial Threading\u003c\/strong\u003e: Fully 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: 1\/2 inch\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 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\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: 40265\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699714294066,"sku":"40265","price":68.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/911b6ff6df9ca963f864808d852ac8ad.jpg?v=1788379664","url":"https:\/\/voomisupply.com\/products\/value-collection-40265-hex-socket-cap-screw-5-8-18-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
