It features a 1\/2-20 UNF thread size and measures 2-1\/2 inches in length under the head. The screw is machined from alloy steel and finished with a black oxide coating that provides mild corrosion resistance and reduces light reflection on the fastener surface. Drive engagement is via a 3\/8-inch hex socket. This fastener meets ASME\/ANSI B18.3 and ASTM A574 standards, making it appropriate for demanding structural and mechanical assembly work performed by maintenance technicians, machinists, and industrial tradespeople.\u003c\/p\u003e\u003cp\u003eThis cap screw is suited for use in general mechanical assemblies, machine frames, tooling fixtures, and equipment maintenance applications where a recessed hex drive is required. Partial threading allows the unthreaded shank to act as a shoulder or locating feature in precision assemblies. The fine 20-thread-per-inch pitch provides greater clamping force and vibration resistance compared to coarse-thread equivalents of the same diameter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/2-20 UNF fine thread for high clamping load and vibration resistance\u003c\/li\u003e\n\u003cli\u003e2-1\/2 inch length under head with partial threading for shoulder applications\u003c\/li\u003e\n\u003cli\u003e3\/8-inch hex socket drive for standard hex key or socket wrench installation\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction for high tensile strength per ASTM A574\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish for mild corrosion resistance and low-glare appearance\u003c\/li\u003e\n\u003cli\u003eMeets ASME\/ANSI B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1\/2-20 UNF hex socket cap screw for use in any application requiring ASME\/ANSI B18.3 compliant socket head fasteners in that thread size and length.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 3\/8-inch hex key or socket driver; ensure the drive tool is fully seated before applying torque to avoid rounding the socket. Power down or de-energize any equipment before accessing fastener locations on live machinery. Follow applicable machinery safety standards and facility lockout\/tagout procedures prior to disassembly or assembly. Do not substitute this fine-thread fastener in applications specified for coarse UNC thread without verifying thread engagement and load requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-20 UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially 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\/8 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: 011405PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690679992626,"sku":"011405PR","price":1450.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/95d0cf526ac84cbc77cf2daceca48436.jpg?v=1788273850","url":"https:\/\/voomisupply.com\/products\/value-collection-011405pr-hex-socket-cap-screw-1-2-20-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
