The 5 mm hex end engages socket-head cap screws, set screws, and other internal-hex fasteners commonly found in mechanical assemblies, HVAC equipment, pump housings, and electrical enclosures. With an overall length of 3-7\/64 inches (78 mm), the short-arm geometry provides increased torque on the driving end while keeping the tool compact. This metric key is a standard hand tool for HVAC technicians, plumbers, electricians, and mechanical service professionals who work with metric fasteners on a daily basis.\u003c\/p\u003e\n\u003cp\u003eThe PAR37264 is suited for service and installation work on equipment that uses 5 mm metric hex fasteners. Typical applications include tightening set screws on motor couplings, adjusting valve packing glands, securing panel hardware, and general mechanical assembly where a compact tool profile is required. The short-arm configuration is particularly useful when working inside control panels, unit cabinets, or any area where a full-length L-key would be obstructed. This tool is sold individually per package.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5 mm hex end fits standard metric socket-head and set-screw fasteners\u003c\/li\u003e\n  \u003cli\u003eShort-arm design provides clearance in tight or recessed work areas\u003c\/li\u003e\n  \u003cli\u003eOverall length of 3-7\/64 inches (78 mm) keeps the tool compact and easy to handle\u003c\/li\u003e\n  \u003cli\u003eHex end type for direct engagement with internal-hex fasteners\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.043 pounds, suitable for tool pouches and belt 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 5 mm internal-hex fasteners across HVAC, plumbing, electrical, and mechanical service applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eHand tools require no installation, but always ensure power is removed from electrical equipment and refrigerant or fluid systems are depressurized before loosening or tightening fasteners in live systems. Apply steady, controlled force to avoid rounding hex sockets, particularly on stainless or hardened set screws. Inspect the hex key tip for wear or deformation before use to prevent fastener damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 5 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: 3-7\/64 inches (78 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.043 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage 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: PAR37264\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARAMOUNT","offers":[{"title":"Default Title","offer_id":51540681163058,"sku":"PAR37264","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1dc0db9acdb481f657f1ee6a4ad35595.jpg?v=1785861774","url":"https:\/\/voomisupply.com\/products\/paramount-par37264-hex-key-5-mm-short-arm","provider":"Voomi Supply","version":"1.0","type":"link"}
