Featuring a 1\/2-13 UNC thread size and a 3\/8-inch hex drive, this screw is partially threaded with a 2-1\/2-inch length under head. It is manufactured from alloy steel and finished with a black oxide coating that provides mild corrosion resistance and a uniform matte appearance. This fastener meets ASME\/ANSI B18.3 and ASTM A574 standards, making it a reliable choice for machinists, maintenance technicians, and industrial assembly professionals.\u003c\/p\u003e\u003cp\u003eThis screw is suited for use in general industrial and mechanical applications where a recessed hex drive is required for torque control and flush or low-profile installation. The partial threading provides a smooth shank section that improves shear strength and alignment in bolted connections. It is commonly installed in machine frames, jigs, fixtures, and equipment housings where alloy steel strength ratings are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/2-13 UNC thread size for broad compatibility with standard UNC tapped holes\u003c\/li\u003e\n\u003cli\u003e2-1\/2-inch length under head with partial threading for improved shear performance\u003c\/li\u003e\n\u003cli\u003e3\/8-inch hex socket drive for use with standard hex keys and socket drivers\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASTM A574 high-strength requirements\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces light reflection\u003c\/li\u003e\n\u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard-fit fastener for any application requiring a 1\/2-13 UNC partially threaded hex socket cap screw conforming to ASME\/ANSI B18.3 and ASTM A574.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by machinists or maintenance technicians using a 3\/8-inch hex key or socket driver. Ensure the mating tapped hole is clean and free of debris before installation. Apply appropriate thread lubricant or threadlocker as required by the assembly specification. Do not exceed the rated torque for the fastener grade as specified in ASME standards for 1\/2-13 alloy steel cap screws.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13 UNC\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\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: Partial\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\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: MP33668\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698422972722,"sku":"MP33668","price":23.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/530c7bcf28ae1af142b734d5a0b6ac2f.jpg?v=1788362600","url":"https:\/\/voomisupply.com\/products\/value-collection-mp33668-hex-socket-cap-screw-1-2-13-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
