Manufactured from alloy steel with a black oxide finish, it delivers a hardness rating of 38 HRC and meets ANSI\/ASME B18.3 and ASTM F835 standards. The hex socket drive accepts a 5\/32-inch hex key for precise torque application in confined spaces. The fully threaded shank follows UNC thread form with a 3A fit class and right-hand thread direction. Machinists, millwrights, and maintenance technicians install this fastener in assemblies where a flush or semi-flush head profile is required.\u003c\/p\u003e\u003cp\u003eThis screw suits general industrial, mechanical, and structural assembly work where a standard hex cap screw head profile would interfere with mating components or covers. The button head style distributes clamping load over a wider bearing surface than a flat head, making it appropriate for sheet metal panels, guards, jigs, fixtures, and equipment housings. The black oxide finish provides mild corrosion resistance in dry or lightly oiled indoor environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eButton head profile with a 0.437-inch head diameter and 0.132-inch head height for low-profile installations\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction rated at 38 HRC hardness for reliable clamping strength\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish for mild corrosion resistance and reduced light reflection\u003c\/li\u003e\n\u003cli\u003e5\/32-inch hex socket drive for precise torque with standard hex keys\u003c\/li\u003e\n\u003cli\u003eFully threaded 1\/4-20 UNC shank with 3A fit class for consistent thread engagement\u003c\/li\u003e\n\u003cli\u003eMeets ANSI\/ASME B18.3 and ASTM F835 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard-service fastener for any assembly specifying a 1\/4-20 UNC button socket cap screw per ANSI\/ASME B18.3.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists, millwrights, or maintenance technicians using a 5\/32-inch hex key or hex bit driver. De-energize and lock out equipment before servicing fasteners on live machinery per applicable OSHA lockout\/tagout procedures. Apply a thread lubricant or anti-seize compound where specified by the assembly drawing to achieve accurate clamp load from applied torque. Do not exceed the designed thread engagement depth for the mating material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 7\/8 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: 5\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.437 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.132 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\u003eHardness\u003c\/strong\u003e: 38 HRC\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\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: 64048\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51739544584498,"sku":"64048","price":2342.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c90b2708bef8140ebf26c33dba225875.jpg?v=1788816051","url":"https:\/\/voomisupply.com\/products\/holo-krome-64048-button-socket-cap-screw-1-4-20","provider":"Voomi Supply","version":"1.0","type":"link"}
