Each key features a ball-end tip that allows engagement at off-axis angles, useful when fastener access is limited or obstructed. The long-arm design provides extended reach and increased torque leverage compared to standard-length keys. The set covers sizes from 1.5 mm through 10 mm, spanning the most common metric hex fasteners found in equipment panels, motor mounts, valve assemblies, and access covers.\u003c\/p\u003e\n\u003cp\u003eThis set suits professionals who regularly encounter metric hex fasteners on commercial and residential equipment. The ball-end tip engages at angles up to approximately 25 degrees off-axis, reducing the need to reposition in tight spaces. The included sizes cover the range most frequently required when servicing HVAC units, pump assemblies, electrical enclosures, and related mechanical equipment. The long-arm configuration also allows the short arm to be used as a driver for added torque when needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBall-end tip on each key allows off-axis engagement for use in restricted or angled access situations\u003c\/li\u003e\n  \u003cli\u003eLong-arm style provides extended reach and improved leverage at the handle end\u003c\/li\u003e\n  \u003cli\u003e9-piece set covers 1.5, 2, 2.5, 3, 4, 5, 6, 8, and 10 mm metric sizes\u003c\/li\u003e\n  \u003cli\u003eDual-function design: long arm for reach, short arm for torque\u003c\/li\u003e\n  \u003cli\u003eCompact set format keeps all sizes organized and portable on the job\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard metric internal hex fasteners across residential and commercial HVAC, plumbing, electrical, and mechanical equipment applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInsert the key fully into the fastener socket before applying torque to avoid rounding the hex drive. Use the ball end only for initial loosening or final snugging, not for high-torque applications where full flat-face engagement is required. Keep keys clean and free of debris to maintain a proper fit in precision fastener sockets.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size Range\u003c\/strong\u003e: 1.5 to 10 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMetric Sizes Included\u003c\/strong\u003e: 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePiece Count\u003c\/strong\u003e: 9\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArm Style\u003c\/strong\u003e: Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBall End\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.06 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: WERA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 05073391001\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WERA","offers":[{"title":"Default Title","offer_id":51972053762354,"sku":"05073391001","price":35.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/57715ef0072cc013dfd3f953682c777e.jpg?v=1789962127","url":"https:\/\/voomisupply.com\/products\/wera-05073391001-metric-long-arm-ball-end-hex-key-set","provider":"Voomi Supply","version":"1.0","type":"link"}
