Featuring a 1\/2-13 UNC thread size and a 3\/8-inch hex drive socket, this screw is partially threaded with 3 inches of length under the head. It is manufactured from alloy steel with a black oxide coating that provides moderate corrosion resistance and reduces light reflection in service environments. Machinists, millwrights, maintenance technicians, and general contractors typically install this fastener wherever a recessed drive profile and high clamp load are required.\u003c\/p\u003e\u003cp\u003eThis cap screw is suited for use in structural steel fabrication, machine frames, fixtures, jigs, and industrial maintenance applications. The partially threaded shank provides a bearing surface in the clearance hole, which is useful for precision alignment in bolted joint assemblies. It conforms to ASME\/ANSI B18.3 and ASTM A574 standards, making it appropriate for demanding mechanical and structural applications where fastener grade and dimensional consistency matter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/2-13 UNC thread for broad compatibility with standard inch-series tapped holes\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank provides shear load capacity and alignment in clearance holes\u003c\/li\u003e\n\u003cli\u003e3\/8-inch hex socket drive for use with Allen keys and hex bit drivers\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASTM A574 high-strength requirements\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish for mild corrosion resistance and low-glare appearance\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 a standard ASME\/ANSI B18.3 hex socket cap screw for use in any application requiring a 1\/2-13 UNC partially threaded fastener with a 3\/8-inch hex drive.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall using a 3\/8-inch hex key or socket bit driver rated for the required torque. Ensure the mating tapped hole is clean and free of debris before driving. Follow applicable torque specifications from your engineering documentation or applicable ASME standards for ASTM A574 alloy steel fasteners. Do not exceed the fastener's rated clamp load, and avoid cross-threading during installation.\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: 3 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\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: 33670\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691069866290,"sku":"33670","price":26.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b337253930c8325eee3ab880aa2478b1.jpg?v=1788279954","url":"https:\/\/voomisupply.com\/products\/value-collection-33670-hex-socket-cap-screw-1-2-13-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
