Sized at 4-40 UNC with a 1\/8 inch length under head, this screw is fully threaded and driven with a 3\/32 inch hex key. The alloy steel construction delivers solid tensile strength for its size class, and the black oxide coating provides a measure of corrosion resistance and surface hardness. It is commonly installed by machinists, assembly technicians, and maintenance professionals working on light mechanical assemblies, electrical enclosures, and precision equipment.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for applications requiring a fine 4-40 UNC thread pitch in tight-clearance environments. The socket cap head allows driving in recessed or confined spaces where a standard hex head wrench cannot reach. Typical use cases include instrument panels, circuit board standoffs, small motor housings, and other light-duty mechanical assemblies where controlled torque and flush or recessed fastener seating are necessary. This item is sold individually but carries a minimum order quantity of 100 units per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-40 UNC thread size for fine-pitch, high-precision fastening\u003c\/li\u003e\n  \u003cli\u003eFully threaded along the 1\/8 inch length under head for maximum thread engagement\u003c\/li\u003e\n  \u003cli\u003e3\/32 inch hex socket drive for use with standard Allen or hex key tools\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASME\/ANSI B18.3 and ASTM A574 standards\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish reduces surface corrosion and minimizes light reflection in low-visibility assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 4-40 UNC hex socket cap screw per ASME\/ANSI B18.3, suitable for use in any tapped hole or threaded insert conforming to 4-40 UNC specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall with a calibrated hex key or Allen driver sized at 3\/32 inch. Verify that mating threads are clean and free of debris before driving. Avoid over-torquing this small-diameter fastener, as alloy steel screws at the 4-40 size can be susceptible to thread stripping in softer base materials. Follow applicable assembly or equipment manufacturer torque guidelines when specified.\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 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully Threaded\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: 3\/32 inch\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\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM A574\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: 581113PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51703837851954,"sku":"581113PR","price":3180.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f7b9d8899f52b8c0123f124b9cb1e53f.jpg?v=1788418900","url":"https:\/\/voomisupply.com\/products\/value-collection-581113pr-hex-socket-cap-screw-4-40-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
