Sized at 1\/2-13 UNC thread with a 4.25-inch length under head, this fastener is partially threaded and driven by a 3\/8-inch hex key. Constructed from alloy steel with a black oxide finish coating, it delivers reliable clamping force and moderate corrosion resistance. Manufactured to ASME\/ANSI B18.3 and ASTM A574 standards, this screw meets the mechanical property requirements expected in precision and load-bearing fastener applications. Each package contains 10 screws.\u003c\/p\u003e\u003cp\u003eThis screw is suited for use in machine assembly, tooling fixtures, equipment maintenance, and general industrial fastening where a recessed hex drive and high tensile alloy steel construction are required. The 1\/2-13 UNC coarse thread is a widely used size in North American industrial and OEM equipment. The partial thread configuration provides a stronger grip in thick materials and is preferred in through-bolt and clamp-load applications. Installers across maintenance, machining, and fabrication trades commonly use this fastener type.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/2-13 UNC coarse thread for compatibility with standard North American hardware\u003c\/li\u003e\n\u003cli\u003e4.25-inch length under head accommodates thicker material stacks\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank for improved shear strength and clamping performance\u003c\/li\u003e\n\u003cli\u003e3\/8-inch hex socket drive for use with standard Allen keys and hex bit drivers\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASTM A574 high-strength fastener requirements\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces light reflection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1\/2-13 UNC hex socket cap screw suitable for use in machinery, fixtures, and equipment that accept ASME\/ANSI B18.3 socket head cap screws of this thread size and length.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified mechanic, millwright, or maintenance technician using the appropriate 3\/8-inch hex key or socket head driver. De-energize and lock out all affected equipment before fastener installation or removal per applicable OSHA lockout\/tagout procedures. Apply thread lubricant or thread locker only as specified by the equipment manufacturer. Do not substitute this fastener in applications requiring a different thread class, grade, or plating specification without engineering review.\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: 4.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\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\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\u003ePackage Quantity\u003c\/strong\u003e: 10 pieces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\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: A997144\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695881617714,"sku":"A997144","price":42.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3269f42183061b3f714a11d40aa2b1a9.jpg?v=1788339028","url":"https:\/\/voomisupply.com\/products\/value-collection-a997144-hex-socket-cap-screw-1-2-13-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
