Manufactured from alloy steel with a black oxide finish, this screw features a 5\/16-24 UNF thread and measures 5\/8 inches in length under the head. The hex socket drive accepts a 3\/16-inch hex key for installation. With a hardness rating of 38 HRC and a 3A thread fit class, the 65030 meets ANSI\/ASME B18.3 and ASTM F835 standards. It is fully threaded with a right-hand thread direction, making it a reliable choice for precision mechanical assemblies across industrial and trade applications.\u003c\/p\u003e\n\u003cp\u003eThis button socket cap screw is suited for use in machinery, fixtures, and fabricated assemblies where a rounded, low-profile head is required to clear adjacent components or reduce snag hazards. The black oxide finish provides mild corrosion resistance and a uniform dark appearance. Licensed trades and industrial maintenance professionals commonly use this fastener when working within tight clearances or in applications where a standard hex head cap screw would interfere with surrounding hardware.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eButton head profile reduces snag hazards and fits flush in low-clearance assemblies\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction with 38 HRC hardness for high-strength fastening\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for mild corrosion resistance and uniform appearance\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch hex socket drive for precise torque application\u003c\/li\u003e\n  \u003cli\u003eFully threaded 5\/16-24 UNF right-hand thread, 3A fit class\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI\/ASME B18.3 and ASTM F835 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNF button socket cap screw compatible with 5\/16-24 threaded holes in industrial machinery, fabricated assemblies, and mechanical fixtures requiring a low-profile alloy steel fastener.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed using a 3\/16-inch hex key or allen driver. Ensure the mating threaded hole is clean and free of debris before driving the fastener. Apply thread locker or specified torque values per the equipment manufacturer's guidelines and applicable ANSI standards. Do not over-torque, as this may compromise thread integrity or head seating.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNRF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Fit Class\u003c\/strong\u003e: 3A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Button\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.547 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.166 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: 3\/16 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\u003eHardness\u003c\/strong\u003e: 38 HRC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ANSI\/ASME B18.3, ASTM F835\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\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: HOLO-KROME\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 65030\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51731757203762,"sku":"65030","price":5440.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/436aaba2d2fc4078df792954e447e6d2.jpg?v=1788734604","url":"https:\/\/voomisupply.com\/products\/holo-krome-65030-button-socket-cap-screw-5-16-24","provider":"Voomi Supply","version":"1.0","type":"link"}
