The screw features a 4-40 UNC thread, a 1-inch length under the head, and is fully threaded along its entire shank. It is driven by a 1\/16-inch hex socket. Manufactured from alloy steel with a black oxide coating, this fastener delivers corrosion resistance and a dark matte finish suited for mechanical assemblies, electronic enclosures, and precision equipment. Hardness is rated at 36-43 HRC per ASTM F835 requirements.\u003c\/p\u003e\u003cp\u003eThis screw is a standard choice in light mechanical and electronic assembly work where a flush or near-flush head profile is needed. The button head style distributes clamping load over a wider bearing surface than a flat head, making it common in sheet metal work, panel mounting, and instrument fabrication. The black oxide finish helps reduce light reflection and provides mild surface protection in dry indoor environments. It is installed by machinists, assembly technicians, and maintenance trades working on precision or electronic equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-40 UNC fully threaded shank with right-hand thread direction\u003c\/li\u003e\n\u003cli\u003eButton head profile provides low clearance and broad bearing surface\u003c\/li\u003e\n\u003cli\u003e1\/16-inch hex socket drive for use in tight or recessed locations\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction rated 36-43 HRC for consistent strength\u003c\/li\u003e\n\u003cli\u003eBlack oxide coating reduces reflection and adds mild corrosion resistance\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 hardware component for assemblies requiring a 4-40 UNC button socket cap screw per ANSI\/ASME B18.3 and ASTM F835 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall and remove using a 1\/16-inch hex key or Allen driver. Power down or de-energize any electrical enclosure before servicing fasteners in live assemblies. Do not exceed the torque rating specified by the host assembly design, as the small 4-40 thread is susceptible to overtorque damage. Thread fit class 3A is intended for standard close-tolerance applications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 1 inch\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 inch\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\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 701033PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715102441778,"sku":"701033PR","price":4358.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c79c77aebc472e04c836783b4acf2735.jpg?v=1788509574","url":"https:\/\/voomisupply.com\/products\/value-collection-701033pr-button-socket-cap-screw-4-40","provider":"Voomi Supply","version":"1.0","type":"link"}
