Manufactured from alloy steel with a black oxide finish, this screw features a 1\/4-28 UNF thread and a 1\/2-inch length under head. It is fully threaded and driven by a 5\/32-inch hex socket. Hardness is rated at 36-43 HRC, making it suitable for demanding mechanical assemblies. It conforms to ANSI\/ASME B18.3 and ASTM F835 standards. The button head profile reduces stress concentration and sits flush in countersunk or clearance applications. Machinists, maintenance technicians, and fabricators are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis fastener is used in general industrial, mechanical, and fabrication applications where a low-profile head is needed and where a standard hex socket drive is preferred. The 1\/4-28 fine thread pitch provides strong clamping force in metal-to-metal assemblies. Black oxide finish offers mild corrosion resistance and a clean appearance suited to exposed mechanical components. Typical applications include machine guarding, fixture building, equipment frames, and enclosure assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eButton head low-profile design reduces snag points in mechanical assemblies\u003c\/li\u003e\n  \u003cli\u003e1\/4-28 UNF fully threaded, Class 3A thread fit for precise engagement\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction with 36-43 HRC hardness rating\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating provides mild corrosion and wear resistance\u003c\/li\u003e\n  \u003cli\u003e5\/32-inch hex socket drive for standard Allen key or bit installation\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI\/ASME B18.3 and ASTM F835 dimensional and material standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-dimension replacement or general-use fastener for any application requiring a 1\/4-28 UNF button socket cap screw per ANSI\/ASME B18.3 and ASTM F835 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 5\/32-inch hex key or socket bit driver. Ensure mating threads are clean and free of debris before installation. Do not exceed the rated torque capacity of the alloy steel material for the 1\/4-28 thread size as specified in applicable engineering references. Black oxide finish is not a heavy-duty corrosion barrier — apply supplemental coating or lubricant if the fastener will be exposed to moisture or chemicals.\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: 0.5 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\/Coating\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: 201107PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690596630834,"sku":"201107PR","price":1979.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ef9ff2cd94dcd7086f18da95ec86d5cb.jpg?v=1788272334","url":"https:\/\/voomisupply.com\/products\/value-collection-201107pr-button-socket-cap-screw-1-4-28","provider":"Voomi Supply","version":"1.0","type":"link"}
