The low-profile button head reduces snag risk in assemblies where standard hex cap screws would protrude too far. Manufactured from alloy steel with a black oxide finish, this screw provides moderate corrosion resistance and a clean appearance. The 1\/16-inch hex socket drive requires an appropriate Allen key or hex bit driver. With a thread fit class of 3A and right-hand UNC threading, it meets ANSI\/ASME B18.3 and ASTM F835 standards. Hardness is rated at 36 to 43 HRC, making it suitable for moderate-load mechanical assemblies.\u003c\/p\u003e\n\u003cp\u003eThis fastener is used in light mechanical, electronic, and instrumentation assemblies where a low-profile head is required. The 4-40 UNC thread size is common in precision equipment, panel fabrication, and small-component mounting. The black oxide finish suits indoor or protected environments. Fully threaded along the 0.25-inch under-head length, the screw engages the full depth of shallow threaded holes without a grip-length gap. This item is sold individually but requires a minimum order quantity of 100 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eButton head profile reduces protrusion in flush or low-clearance assemblies\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction with 36 to 43 HRC hardness for moderate-load applications\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and a uniform matte appearance\u003c\/li\u003e\n  \u003cli\u003eFully threaded at 0.25 inches under-head length for maximum thread engagement in shallow holes\u003c\/li\u003e\n  \u003cli\u003e1\/16-inch hex socket drive for precise torque application with standard Allen tools\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 an OEM-style replacement or maintenance fastener for any assembly requiring a 4-40 UNC, 0.25-inch under-head length button socket cap screw with a 3A thread fit class.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a 1\/16-inch hex key or Allen driver. Ensure the mating threaded hole is clean and free of debris before driving. Do not exceed the torque capacity of the 4-40 thread to avoid stripping or fastener failure. For assemblies subject to vibration, consider thread-locking compound appropriate for the service environment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Button\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.059 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: 1\/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\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 36 to 43 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\u003eWeight\u003c\/strong\u003e: 0.00106 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 201017P\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693058916658,"sku":"201017P","price":1869.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/880583e2a54e75adbf1b3a7659627b06.jpg?v=1788306758","url":"https:\/\/voomisupply.com\/products\/value-collection-201017p-button-socket-cap-screw-4-40","provider":"Voomi Supply","version":"1.0","type":"link"}
