This fastener features a 1\/2-20 UNF thread size with a 2-1\/4 inch length under the head and is driven with a 3\/8 inch hex key. Constructed from alloy steel with a black oxide finish coating, it delivers corrosion resistance and a clean, low-glare appearance. The partial threading design provides clamping force where it matters most. Machinists, millwrights, and maintenance technicians working on precision equipment will find this screw suitable for demanding load-bearing installations.\u003c\/p\u003e\u003cp\u003eThis screw is used in applications requiring fine-thread engagement and high tensile strength, including industrial equipment assembly, tooling fixtures, machine frames, and general mechanical fabrication. The 1\/2-20 UNF thread pitch offers tighter thread engagement than coarse-thread equivalents, making it appropriate where vibration resistance or precision torque control is important. The black oxide coating is common in shop and industrial environments where a non-reflective surface finish is preferred. This fastener is sold in minimum order quantities of 10 pieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/2-20 UNF fine thread for tight engagement and vibration resistance\u003c\/li\u003e\n\u003cli\u003e2-1\/4 inch length under head for moderate-depth fastening applications\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction for high tensile and shear strength\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish coating for corrosion resistance and low-glare appearance\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank for accurate clamping in bolted joints\u003c\/li\u003e\n\u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM A574 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard hex socket cap screw for use in any application requiring a 1\/2-20 UNF thread pattern with a 3\/8 inch hex drive and a 2-1\/4 inch length under head.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 3\/8 inch hex key or Allen driver. Power down any equipment and relieve any mechanical loads before replacing fasteners in load-bearing assemblies. Follow applicable ASME torque guidelines for the fastener grade and thread size. Verify thread engagement depth in the mating component before final tightening to avoid stripping or under-seating.\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\/4 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\/8 inches\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: Alloy Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3 and ASTM A574\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: 011403PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51705870385458,"sku":"011403PR","price":1464.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/50b6383af1cdebc647f5e128ad2f37c5.jpg?v=1788431571","url":"https:\/\/voomisupply.com\/products\/value-collection-011403pr-hex-socket-cap-screw-1-2-20-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
