Built from Protanium High Torque Steel, this 12 mm metric key delivers reliable torque transfer without deforming under load. The short arm configuration provides additional leverage at the driving end while keeping the tool compact. Overall length is 4-51\/64 inches (4.8 inches decimal). It is a hand tool suited for mechanical, HVAC, plumbing, and electrical tradespeople who encounter metric hex fasteners during equipment installation, service, or component replacement.\u003c\/p\u003e\n\u003cp\u003eThis hex key is appropriate for general trade use wherever 12 mm metric hex fasteners are present. Common applications include tightening set screws on motor couplings, fan hubs, valve stems, and mechanical assemblies found in residential and commercial HVAC equipment, pump systems, and industrial machinery. The short arm style makes it easier to work in tight enclosures or panel interiors where a standard long-arm key cannot clear adjacent components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eProtanium High Torque Steel construction resists deformation under high-torque driving conditions\u003c\/li\u003e\n  \u003cli\u003e12 mm metric hex size covers common large-format set screws and fasteners in mechanical assemblies\u003c\/li\u003e\n  \u003cli\u003eShort arm design improves access in confined spaces and tight equipment enclosures\u003c\/li\u003e\n  \u003cli\u003eHex end tip for direct engagement with socket-head and set-screw fasteners\u003c\/li\u003e\n  \u003cli\u003eGray handle provides visual identification and comfortable grip during use\u003c\/li\u003e\n  \u003cli\u003eCompact overall length of 4-51\/64 inches suits toolbox portability and field service kits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose metric hex key for use with 12 mm hex fasteners across a wide range of mechanical, HVAC, plumbing, and electrical equipment assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is used by licensed HVAC technicians, plumbers, electricians, and mechanical tradespeople during equipment service or installation. Always de-energize and lock out electrical equipment and shut off fluid systems before servicing components secured by hex fasteners. Inspect the key tip for wear before use; a worn or rounded tip can damage fastener sockets. Apply steady, controlled force to avoid rounding fastener heads, particularly on stainless or hardened hardware.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 12 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: Short\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-51\/64 inches (4.8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Range\u003c\/strong\u003e: 4 to 6.9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Protanium High Torque Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Color\u003c\/strong\u003e: Gray\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: 6.5 inches L x 4 inches W x 1.25 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 pounds\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: PAR37280\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARAMOUNT","offers":[{"title":"Default Title","offer_id":51542225027378,"sku":"PAR37280","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d2e3743f81603e00c2648d9fe0e7687c.jpg?v=1785895622","url":"https:\/\/voomisupply.com\/products\/paramount-par37280-hex-key-12mm-short-arm-metric","provider":"Voomi Supply","version":"1.0","type":"link"}
