This screw features a 1\/4-28 UNF thread form, a 1-1\/4 inch length under head, and is fully threaded along its entire shank. It is driven with a 3\/16 inch hex key. Constructed from alloy steel with a black oxide finish, the 40220 delivers solid corrosion resistance and surface hardness. It is a standard choice for mechanical assemblies, equipment repair, and fabrication work across industrial and trade environments.\u003c\/p\u003e\n\u003cp\u003eThis screw suits residential and commercial applications where fine-threaded fasteners are required for controlled tension and vibration resistance. Typical uses include machine component assembly, equipment mounting brackets, enclosure panels, and general mechanical repairs. The 1\/4-28 UNF thread pitch is common in precision assemblies where fine thread engagement is preferred over coarse thread alternatives. Trades including HVAC technicians, electricians, pipefitters, and general maintenance mechanics regularly use socket cap screws of this type during equipment installation and repair.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-28 UNF fully threaded shank for maximum thread engagement\u003c\/li\u003e\n  \u003cli\u003e1-1\/4 inch length under head suits moderate-depth fastening applications\u003c\/li\u003e\n  \u003cli\u003e3\/16 inch hex drive allows installation in confined or recessed locations\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASME\/ANSI B18.3 and ASTM A574 fastener standards\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating provides mild corrosion resistance and reduces light reflection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard component for any assembly requiring a 1\/4-28 UNF hex socket cap screw with a 1-1\/4 inch length under head and 3\/16 inch hex drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a 3\/16 inch hex key or Allen driver. Power down and de-energize any equipment before replacing fasteners on live assemblies. Follow applicable torque guidelines from the equipment manufacturer for 1\/4-28 UNF fasteners to avoid thread stripping in the mating material. Verify that the mating thread is also UNF fine pitch before installation.\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 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1-1\/4 inches\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\/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\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3 and 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: 40220\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722095657266,"sku":"40220","price":28.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/011fcc6c784705fa5a028680714bee29.jpg?v=1788585621","url":"https:\/\/voomisupply.com\/products\/value-collection-40220-hex-socket-cap-screw-1-4-28-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
