Manufactured from steel, this metric hex key features a 3.00 mm hex end and measures 3-7\/8 inches overall in length. The long arm configuration provides increased torque leverage and extended reach compared to standard short-arm keys. It is a hand tool suited for HVAC equipment assembly, mechanical component service, and general trade maintenance where metric fasteners are common. Technicians working on equipment panels, fan assemblies, and mechanical linkages will find this key a standard addition to their service kit.\u003c\/p\u003e\n\u003cp\u003eThis hex key is used across residential and light commercial service applications wherever 3.00 mm metric hex fasteners are encountered. Typical install scenarios include field assembly, equipment panel removal, and component adjustments on HVAC units, pumps, and mechanical systems. The long arm style makes it easier to access fasteners set deep within equipment housings or behind panels without the need for power tools.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3.00 mm metric hex end for driving hex socket fasteners\u003c\/li\u003e\n  \u003cli\u003eLong arm style provides extended reach and improved torque leverage\u003c\/li\u003e\n  \u003cli\u003e3-7\/8 inches overall length for deep-access applications\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability under standard service loads\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.17 pounds for easy carry in a service bag\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard metric hex key for use with any 3.00 mm hex socket fastener in residential and commercial trade service applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is used by HVAC technicians, plumbers, electricians, and general mechanical trades. Before using a hex key on equipment fasteners, power down the unit and follow all applicable lockout\/tagout procedures. Ensure the hex key is fully seated in the fastener socket before applying torque to avoid rounding the fastener. Do not use extension bars or excessive force that could deform the key or fastener.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 3.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Hex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArm Style\u003c\/strong\u003e: Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-7\/8 inches (3.88 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 5.5 inches L x 3 inches W x 0.5 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.17 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eItem Package Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27111710\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: PARAMOUNT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: PAR37156\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARAMOUNT","offers":[{"title":"Default Title","offer_id":51542995927346,"sku":"PAR37156","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6bd11b41ed5aa14e97e70250e4145a62.jpg?v=1785913294","url":"https:\/\/voomisupply.com\/products\/paramount-par37156-hex-key-3-00-mm-long-arm-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
