Grade 8 steel provides high tensile strength suited to demanding mechanical and structural fastening applications. The zinc yellow dichromate coating adds corrosion resistance for use in environments where moisture or mild chemical exposure is a concern. This fastener conforms to ASME B18.2.1 standards and uses a UNC thread form. It is a stock item for maintenance crews, millwrights, fabricators, and trade contractors who require a reliable, high-strength inch-series fastener for bolted connections.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used wherever a high-strength, partially threaded hex fastener is required in inch-series mechanical assemblies. Typical applications include structural steel connections, equipment mounting, machinery frames, and general industrial maintenance. The partial thread configuration allows the unthreaded shank to bear shear loads while the threaded end engages a nut or tapped hole. It is commonly used in fabrication shops, manufacturing facilities, and on commercial job sites across HVAC, plumbing, and electrical equipment mounting scenarios.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank allows shear load transfer through the bolt body\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC thread form for broad nut and tapped-hole compatibility\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish provides corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standards\u003c\/li\u003e\n  \u003cli\u003e6-inch length under head accommodates thicker material stacks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any application requiring a 1\/2-13 UNC partially threaded hex head cap screw meeting ASME B18.2.1 specifications.

Ensure mating threads and seating surfaces are clean and free of debris before installation. Torque to the appropriate Grade 8 specification for the joint design per applicable engineering standards. Do not use impact tools at excessive speed, as this can damage the zinc dichromate coating and reduce corrosion protection.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc Yellow Dichromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensional Standard\u003c\/strong\u003e: ASME B18.2.1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: D39120\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690286743858,"sku":"D39120","price":30.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f251a7cd2c840ad18ea747df4077024f.jpg?v=1788268168","url":"https:\/\/voomisupply.com\/products\/value-collection-d39120-hex-head-cap-screw-1-2-13-x-6-in","provider":"Voomi Supply","version":"1.0","type":"link"}
