The button head style provides a wider bearing surface than a standard socket cap screw while keeping the overall head height low at 0.199 inches. Manufactured from alloy steel with a black oxide finish, this screw carries a hardness rating of 38 HRC and meets ANSI\/ASME B18.3 and ASTM F835 standards. The hex socket drive accepts a 7\/32 inch hex key. This fastener is fully threaded and suited for mechanical assemblies, jigs, fixtures, and fabricated steel components.\u003c\/p\u003e\u003cp\u003eThis screw is a common choice in industrial maintenance, machine building, and structural assembly work where flush or near-flush fastening is preferred. The black oxide finish provides mild corrosion resistance and reduces light reflection, making it appropriate for tooling plates, guards, and equipment enclosures. The 3A thread fit class ensures a snug, precise fit in tapped holes. Installation is typically performed by machinists, millwrights, maintenance technicians, and general fabricators working with ferrous and alloy steel assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eButton head profile with a head height of 0.199 inches and head diameter of 0.656 inches for low-profile installations\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction rated at 38 HRC hardness for high-strength fastening\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish for mild corrosion resistance and reduced surface reflectivity\u003c\/li\u003e\n\u003cli\u003e3A thread fit class with right-hand UNRC thread for precise engagement in standard tapped holes\u003c\/li\u003e\n\u003cli\u003eMeets ANSI\/ASME B18.3 and ASTM F835 fastener standards\u003c\/li\u003e\n\u003cli\u003eFully threaded along the 3\/4 inch length under head for maximum thread engagement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style and general-use replacement or addition for standard 3\/8-16 UNC tapped holes requiring a button socket cap screw per ANSI\/ASME B18.3.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 7\/32 inch hex key or hex socket bit driver. Ensure the mating tapped hole is clean and free of debris before driving the fastener. Apply appropriate thread lubricant or thread-locking compound as required by the assembly specification. Do not exceed the rated torque for the alloy steel material grade and thread size as defined by your applicable engineering or maintenance standard.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Button\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: 7\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.199 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.656 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\u003eThread Standard\u003c\/strong\u003e: UNRC\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\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\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 64068\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51727278375218,"sku":"64068","price":4688.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6c7f022e73c64070ecdb0b0800d916e4.jpg?v=1788675809","url":"https:\/\/voomisupply.com\/products\/holo-krome-64068-button-socket-cap-screw-3-8-16","provider":"Voomi Supply","version":"1.0","type":"link"}
