It features a 1\/2-13 UNC thread size and a 4-1\/2 inch length under head, with a 3\/8 inch hex drive socket for installation with a hex key or Allen wrench. The screw is manufactured from alloy steel and finished with a black oxide coating, which provides mild corrosion resistance and reduces light reflection in service environments. It meets ASME\/ANSI B18.3 and ASTM A574 standards, confirming compliance with dimensional and mechanical property requirements for socket cap screws.\u003c\/p\u003e\u003cp\u003eThis fastener is suited for use in machine tool fixtures, jigs, dies, hydraulic assemblies, and general industrial equipment where a recessed drive and strong clamping force are required. The 1\/2-13 UNC coarse thread pitch is widely compatible with tapped holes in steel, cast iron, and aluminum components. Black oxide alloy steel socket cap screws of this specification are commonly installed by machinists, millwrights, maintenance technicians, and mechanical contractors across manufacturing and industrial service settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/2-13 UNC coarse thread for broad compatibility with standard tapped holes\u003c\/li\u003e\n\u003cli\u003e4-1\/2 inch length under head suits deeper fastening applications\u003c\/li\u003e\n\u003cli\u003e3\/8 inch hex socket drive for use with standard Allen keys or hex bit drivers\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank provides a clamping body section above the threaded engagement zone\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASTM A574 mechanical property requirements\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish offers mild corrosion resistance and a low-reflectance appearance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard ASME\/ANSI B18.3 socket cap screw for use in any application requiring a 1\/2-13 UNC partially threaded hex socket fastener in alloy steel with black oxide finish.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 3\/8 inch hex key or Allen-type driver; ensure the driver is fully seated in the socket before applying torque to prevent cam-out or socket damage. Verify that the mating tapped hole meets 1\/2-13 UNC thread specification and adequate thread engagement depth before assembly. De-energize, depressurize, or lock out any equipment before fastener replacement on active machinery in accordance with applicable OSHA lockout\/tagout procedures. Do not use thread lubricants or anti-seize compounds unless specified by the equipment manufacturer for the application.\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: 4-1\/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 inch\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\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\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: 33675\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722595041586,"sku":"33675","price":29.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c5730ce97a05db844cdc76d82d4bcda0.jpg?v=1788593306","url":"https:\/\/voomisupply.com\/products\/value-collection-33675-hex-socket-cap-screw-1-2-13-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
