Manufactured from Grade 2 steel with a zinc plating finish, this screw measures 1.5 inches under the head and features partial threading along its shank. The 1\/4-20 thread designation indicates a 1\/4-inch nominal diameter with 20 threads per inch, conforming to Unified National Coarse (UNC) standards. Installation requires a 7\/16-inch wrench or socket. This fastener is a common workhorse for light- to medium-duty applications where a fully threaded screw is not required and a clamping grip zone on the shank is preferred.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for residential and light commercial mechanical work, equipment assembly, panel mounting, and general structural fastening where Grade 2 steel meets the load requirements. Partial threading allows the unthreaded shank to pass cleanly through a clearance hole in one member before engaging threads in the receiving material, providing a stronger clamping action in lap-joint and through-bolt applications. It is used regularly by HVAC technicians, plumbers, electricians, and equipment installers for bracket mounting, access panel securing, and general hardware repairs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-20 UNC thread form for broad compatibility with standard nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003ePartial threading provides unthreaded shank grip zone for clamping applications\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction suitable for light- to medium-duty fastening loads\u003c\/li\u003e\n  \u003cli\u003eZinc plating provides basic corrosion resistance for indoor and sheltered installations\u003c\/li\u003e\n  \u003cli\u003e1.5-inch length under head accommodates standard panel and bracket stack-ups\u003c\/li\u003e\n  \u003cli\u003e7\/16-inch hex drive compatible with standard wrenches and sockets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series UNC hex head cap screw compatible with any 1\/4-20 threaded nut, insert, or tapped hole conforming to ASME B18.2.1 dimensional standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 7\/16-inch open-end, box, or socket wrench. Verify that the receiving tapped hole or nut is clean and free of debris before driving the fastener. Do not overtighten Grade 2 fasteners beyond recommended torque ranges for the thread size, as this grade has lower proof load values than Grade 5 or Grade 8 hardware. Follow applicable mechanical codes and equipment manufacturer torque specifications when used in load-bearing or safety-critical assemblies.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC (Unified National Coarse)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Key Size\u003c\/strong\u003e: 7\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: 403022PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700461273394,"sku":"403022PR","price":1004.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/03728e35fa838c62d37a4382c4af77a1.jpg?v=1788390600","url":"https:\/\/voomisupply.com\/products\/value-collection-403022pr-hex-head-cap-screw-1-4-20-x-1-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
