It is manufactured from Protanium High Torque Steel, a material formulated to withstand high torsional loads without rounding the tool or the fastener drive. The overall length is 1.6 inches (1-39\/64 inches), making it well suited for close-quarters work where a long-arm key would not clear surrounding hardware. Technicians across HVAC, plumbing, electrical, and pool service trades keep short-arm hex keys on hand for equipment panels, motor mounts, set screws, and valve packing nuts that use metric fasteners.\u003c\/p\u003e\n\u003cp\u003eThis hex key is used wherever a 1.27 mm metric hex fastener appears in residential or light commercial equipment. Typical applications include small set screws on motor shafts, blower wheel hubs, actuator linkages, and similar hardware found in HVAC air handlers, pump assemblies, and control enclosures. The short-arm style limits available torque, which is appropriate for small fasteners that can be damaged by excessive force. It is sold individually with a minimum order quantity of 10 units, making it practical to stock as a consumable shop tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eProtanium High Torque Steel construction resists torsional deformation under load\u003c\/li\u003e\n  \u003cli\u003e1.27 mm hex size fits small metric set screws and socket fasteners\u003c\/li\u003e\n  \u003cli\u003eShort-arm design provides access in confined or restricted spaces\u003c\/li\u003e\n  \u003cli\u003e1.6 inch overall length keeps the tool compact and easy to store in a pouch or tray\u003c\/li\u003e\n  \u003cli\u003eGray handle color for quick visual identification in a multi-key set\u003c\/li\u003e\n  \u003cli\u003eMetric measurement system — compatible with metric fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose short-arm metric hex key for use with 1.27 mm hex-drive fasteners found in HVAC, plumbing, electrical, and pool equipment across residential and light commercial applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is used by any trade technician who services equipment with metric hex fasteners. Always power down or de-energize equipment and, where applicable, shut off fluid supply before loosening or tightening fasteners. Short-arm hex keys provide less mechanical advantage than long-arm versions — apply steady, controlled force to avoid stripping small fastener sockets. Inspect the tool tip before use and replace if the hex end shows wear or rounding.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 1.27 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArm Style\u003c\/strong\u003e: Short\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Hex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.6 inches (1-39\/64 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: 4.75 inches L x 1.75 inches W x 0.5 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0169 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eItem Package Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: PAR37249\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARAMOUNT","offers":[{"title":"Default Title","offer_id":51541408579890,"sku":"PAR37249","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5bfd5084bdfe9b822dbf80cc1384709b.jpg?v=1785875121","url":"https:\/\/voomisupply.com\/products\/paramount-par37249-hex-key-1-27-mm-short-arm","provider":"Voomi Supply","version":"1.0","type":"link"}
