Built on a T-handle platform with a cushion grip, this tool gives technicians better rotational leverage than a standard L-key while keeping hand fatigue low during extended use. The ball-end tip allows driving at off-angles, making it useful when straight access to a fastener is blocked. The steel construction handles the demands of daily field work. At 6 inches overall length, it fits comfortably in hand and into most service pouches. Licensed electricians, HVAC technicians, plumbers, and general mechanical tradespeople will find this a reliable addition to a metric hand-tool kit.\u003c\/p\u003e\n\u003cp\u003eThis hex key is suited for residential and light commercial service work where metric fasteners are common, including equipment panels, motor mounts, access covers, and component brackets. The T-handle format is particularly practical when technicians need sustained torque on recessed socket-head cap screws. It is sold individually, making it a straightforward replacement or supplement to an existing metric set.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4 mm metric hex tip for standard metric socket-head fasteners\u003c\/li\u003e\n  \u003cli\u003eBall-end design allows driving at angles up to approximately 30 degrees off-axis\u003c\/li\u003e\n  \u003cli\u003eT-handle cushion grip provides increased torque and reduced hand fatigue\u003c\/li\u003e\n  \u003cli\u003eSteel blade and body built for durable field use\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length for reach into recessed fastener locations\u003c\/li\u003e\n  \u003cli\u003eNon-insulated — not rated for live electrical work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose metric hex key compatible with 4 mm socket-head cap screws and set screws across HVAC, plumbing, electrical, and mechanical applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is non-insulated and must not be used near energized conductors or live electrical components. Ensure all equipment is de-energized and locked out before accessing fasteners inside panels or equipment enclosures. The ball-end tip is intended for moderate-torque applications at an angle — use the straight-axis engagement for final tightening to avoid tip wear. Standard hand-tool safety practices apply.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 4 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Ball End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Type\u003c\/strong\u003e: T-Handle Cushion Grip\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlade Length\u003c\/strong\u003e: 6 inches (152.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsulated\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: KLEIN TOOLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: JTH6M4BE\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KLEIN TOOLS","offers":[{"title":"Default Title","offer_id":51538914738482,"sku":"JTH6M4BE","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eb9a88fc2e5755fc022d1b912217a13c.jpg?v=1785829491","url":"https:\/\/voomisupply.com\/products\/klein-tools-jth6m4be-4mm-ball-end-t-handle-hex-key","provider":"Voomi Supply","version":"1.0","type":"link"}
