It features a 1\/4-20 UNC thread size and a 1-inch length under head, with full threading along the shank for maximum thread engagement. The drive is a 3\/16-inch hex socket, accepting a standard Allen key or hex bit driver. Manufactured from alloy steel with a black oxide finish, this fastener offers solid tensile strength and moderate corrosion resistance in protected indoor environments. It meets ASME\/ANSI B18.3 and ASTM A574 standards.\u003c\/p\u003e\u003cp\u003eThis screw is suited for general industrial and mechanical installation work where a flush or low-profile fastener is required. Its fully threaded design makes it appropriate for through-hole and tapped-hole applications in steel, aluminum, and similar substrates. Typical users include machinists, maintenance technicians, millwrights, and mechanical contractors working on equipment assembly or repair. The black oxide finish provides a clean, non-reflective appearance and minimal dimensional change over the base material.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-20 UNC thread size for compatibility with standard tapped holes and nuts\u003c\/li\u003e\n\u003cli\u003e1-inch length under head, fully threaded for maximum engagement\u003c\/li\u003e\n\u003cli\u003e3\/16-inch hex socket drive accepts standard Allen keys and hex bits\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish for reduced glare and basic surface protection\u003c\/li\u003e\n\u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1\/4-20 UNC hex socket cap screw for use in any tapped hole or threaded application conforming to ASME\/ANSI B18.3 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed using a 3\/16-inch hex key or Allen bit driver; ensure the drive is fully seated before applying torque to avoid cam-out and socket damage. Verify the receiving thread is clean and properly tapped to the UNC standard before installation. De-energize and lock out any equipment before fastener service on live machinery, following applicable OSHA lockout\/tagout procedures. Do not use this fastener in wet or outdoor environments where corrosion resistance beyond black oxide is required without additional protection.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1 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\/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, ASTM A574\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: 33604\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51697792680242,"sku":"33604","price":17.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/889b4488034f07f3da4d91b147c8e9c0.jpg?v=1788354358","url":"https:\/\/voomisupply.com\/products\/value-collection-33604-hex-socket-cap-screw-1-4-20-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
