Measuring 2-1\/4 inches under the head with partial threading, this fastener meets ASME B18.2.1 dimensional standards. Manufactured from Grade 5 steel with a zinc-plated finish, it delivers reliable tensile strength and corrosion resistance suitable for moderate-duty structural and mechanical connections. Electricians, plumbers, HVAC technicians, and general contractors commonly use hardware of this specification when assembling equipment, securing brackets, or mounting system components.\u003c\/p\u003e\u003cp\u003eThis cap screw is suited for use in light to medium-duty fastening applications across residential and commercial trade work. The 1\/4-20 thread size is one of the most common inch-series UNC sizes, making it widely applicable in equipment assembly, panel mounting, and fixture installation. Partial threading allows the shank to bear shear loads more effectively than a fully threaded fastener of the same length, which is useful when clamping two or more members together.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 5 steel construction provides solid tensile and proof load performance for mechanical fastening\u003c\/li\u003e\n\u003cli\u003eZinc-plated finish offers baseline corrosion protection in typical indoor and sheltered environments\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank improves shear load handling and clamping accuracy\u003c\/li\u003e\n\u003cli\u003eConforms to ASME B18.2.1 dimensional standard for consistent fit with standard 1\/4-20 nuts and hardware\u003c\/li\u003e\n\u003cli\u003eUNC thread form is the standard inch-series coarse thread, broadly compatible with off-the-shelf nuts, inserts, and tapped holes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 1\/4-20 UNC nuts, washers, and tapped holes conforming to inch-series thread specifications.

Always de-energize electrical panels and shut off relevant systems before fastening hardware in proximity to live equipment. Use a properly sized wrench or socket to drive the hex head — do not use pliers, which can damage the head and affect torque consistency. Verify that the mating nut or tapped hole matches the 1\/4-20 UNC thread specification before installation to avoid cross-threading.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 2-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensional Standard\u003c\/strong\u003e: ASME B18.2.1\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: 0.01 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: D30009\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720091402546,"sku":"D30009","price":15.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4cca3b0f02eb90f08ea10654eccf0a38.jpg?v=1788560834","url":"https:\/\/voomisupply.com\/products\/value-collection-d30009-hex-head-cap-screw-1-4-20-x-2-1-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
