The screw features a 1\/4-20 UNC thread and a 3\/4-inch length under the head, with full threading along the entire shank. Drive engagement is achieved with a 3\/16-inch hex key. The zinc-plated finish provides a base level of corrosion resistance for general indoor and light-duty applications. This fastener is manufactured to ASME B18.8 and ASTM A574 standards, making it appropriate for controlled mechanical and structural connections where torque and load requirements demand a socket-head design.\u003c\/p\u003e\u003cp\u003eThis cap screw is suited for use in light industrial equipment, machine frames, tooling fixtures, and general mechanical assemblies where a recessed hex drive is preferred. The 1\/4-20 UNC thread is one of the most common fastener threads in North American trade applications, making this screw a standard fit for machine shops, fabrication facilities, and maintenance operations. Full threading ensures maximum thread engagement across the full shank length, which is beneficial in thin-material or blind-hole installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-20 UNC thread for compatibility with standard tapped holes\u003c\/li\u003e\n\u003cli\u003e3\/4-inch length under head with full threading along the entire shank\u003c\/li\u003e\n\u003cli\u003e3\/16-inch hex socket drive for use with standard Allen wrenches or hex keys\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASTM A574 for high tensile strength\u003c\/li\u003e\n\u003cli\u003eZinc-plated finish provides basic corrosion protection for general-use environments\u003c\/li\u003e\n\u003cli\u003eConforms to ASME B18.8 dimensional standards\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 application requiring an ASME B18.8 or ASTM A574 compliant fastener with a 3\/16-inch hex drive.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed with a 3\/16-inch hex key or Allen wrench; use a torque wrench rated for small fasteners when torque specifications are required by the assembly drawing. Ensure the mating tapped hole is clean, properly tapped to 1\/4-20 UNC, and free of debris before driving the screw. Do not exceed the rated tensile strength of the fastener by over-torquing, as alloy steel socket cap screws are susceptible to shear failure under excessive load. Follow applicable ASME or equipment-specific fastener torque tables for final torque values.\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: 0.75 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: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully Threaded\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: Zinc-Plated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME B18.8, ASTM A574\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 872149PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696582459698,"sku":"872149PR","price":4591.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f13e600d9e6eb7206c3c6fcba3c81f35.jpg?v=1788344200","url":"https:\/\/voomisupply.com\/products\/value-collection-872149pr-hex-socket-cap-screw-1-4-20","provider":"Voomi Supply","version":"1.0","type":"link"}
