Each key features a ball end on the long arm, allowing fastener engagement at angles up to 25 degrees without removing and repositioning the tool. The short arm provides the straight drive needed for high-torque seating. Made from steel, these keys are suited for machine assembly, equipment installation, and maintenance tasks where a range of metric hex sizes is required. Technicians across HVAC, mechanical, and general trade applications keep this set as a bench or field staple.\u003c\/p\u003e\n\u003cp\u003eThis set is appropriate for residential and commercial service environments wherever metric hex fasteners are encountered. Typical applications include servicing compressor mounting hardware, motor brackets, access panels, and equipment enclosures. The 9 individual sizes — 1.5 mm, 2 mm, 2.5 mm, 3 mm, 4 mm, 5 mm, 6 mm, 8 mm, and 10 mm — cover the most common metric hex drive fasteners found on HVAC equipment, pumps, and electrical enclosures.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBall end on long arm allows off-axis engagement for faster fastener access in tight spaces\u003c\/li\u003e\n  \u003cli\u003eStraight short arm provides full torque drive for final tightening\u003c\/li\u003e\n  \u003cli\u003e9 metric sizes: 1.5 mm, 2 mm, 2.5 mm, 3 mm, 4 mm, 5 mm, 6 mm, 8 mm, and 10 mm\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability under repeated use\u003c\/li\u003e\n  \u003cli\u003eL-key form factor provides two driving positions per key\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard metric hex socket head fasteners in the 1.5 mm to 10 mm range, as commonly found on HVAC equipment, pumps, motors, and mechanical assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eHand tools require no special licensing but should be used by qualified technicians familiar with proper torque practices. Always select the correct key size to avoid rounding fastener heads. Use the short straight arm for final tightening to prevent over-torquing through the ball end. Inspect keys periodically for wear or deformation and replace any damaged tools before use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 9\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size Range\u003c\/strong\u003e: 1.5 mm to 10 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Sizes\u003c\/strong\u003e: 1.5 mm, 2 mm, 2.5 mm, 3 mm, 4 mm, 5 mm, 6 mm, 8 mm, 10 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBall End\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.07 pounds\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: WIHA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66990\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WIHA","offers":[{"title":"Default Title","offer_id":51692870467890,"sku":"66990","price":64.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bcba4c53306c2d7dead9da51b842840e.jpg?v=1788304315","url":"https:\/\/voomisupply.com\/products\/wiha-66990-ball-end-hex-key-set-1-5-10mm-9-piece","provider":"Voomi Supply","version":"1.0","type":"link"}
