Sized at 1\/4-28 UNF with a 3\/4-inch length under head, this fastener is machined from alloy steel and finished with black oxide coating to provide moderate corrosion resistance and a clean matte appearance. It accepts a 5\/32-inch hex key drive and meets ANSI\/ASME B18.3 and ASTM F835 standards. Hardness is rated at 36-43 HRC, making it suitable for demanding mechanical assemblies where a flush or recessed head is required.\u003c\/p\u003e\n\u003cp\u003eThis button socket cap screw is used across a range of industrial, mechanical, and precision assembly applications. The button head profile distributes clamping load over a wider bearing surface compared to a standard socket head, making it a common choice in machine guarding, enclosure panels, jigs, fixtures, and light structural assemblies. It is appropriate for both OEM manufacturing and field maintenance environments where a hex key wrench is the preferred drive method.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-28 UNF thread standard for fine-thread engagement and vibration resistance\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch length under head, fully threaded\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction rated 36-43 HRC hardness\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for moderate corrosion protection and reduced glare\u003c\/li\u003e\n  \u003cli\u003e5\/32-inch hex socket drive compatible with standard hex keys\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 fine-thread button socket cap screw suitable for use in any application requiring a 1\/4-28 thread and button head profile conforming to ANSI\/ASME B18.3 dimensions.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a machinist, millwright, or maintenance technician using a calibrated 5\/32-inch hex key or Allen driver. Ensure mating threads are clean and free of debris before driving. Do not exceed the fastener hardness rating by pairing with incompatible base materials. Black oxide finish provides minimal corrosion protection and may benefit from supplemental lubrication in wet or outdoor environments.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-28\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\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: 5\/32 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: 36-43 HRC\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  \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: 201111PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51702573203762,"sku":"201111PR","price":1459.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9ab5c0c0a11a586bc75ce15e50beff22.jpg?v=1788412043","url":"https:\/\/voomisupply.com\/products\/value-collection-201111pr-button-socket-cap-screw-1-4-28","provider":"Voomi Supply","version":"1.0","type":"link"}
