The overall length measures 1-45\/64 inches (44.00 millimeters), making it well suited for applications where a standard long-arm key would interfere with surrounding components. The hex end configuration provides direct drive engagement with socket head cap screws and set screws common in HVAC equipment, plumbing fixtures, pool equipment assemblies, and general mechanical installations. Installation and maintenance technicians across multiple trades carry short-arm keys as part of standard hand-tool sets for accessing fasteners in tight panel interiors and equipment housings.\u003c\/p\u003e\n\u003cp\u003eThis hex key is intended for metric fastener applications requiring a 1.50 mm hex drive. It fits typical use cases in light mechanical assembly, equipment servicing, and component adjustment work encountered in residential and commercial trade environments. The short arm style is particularly useful when torque requirements are modest and access clearance is the limiting factor. It is packaged individually and sold in multiples of 10 units minimum.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.50 mm metric hex drive size for precise fastener engagement\u003c\/li\u003e\n  \u003cli\u003eShort arm style for use in restricted-clearance work areas\u003c\/li\u003e\n  \u003cli\u003eHex end type provides direct socket engagement\u003c\/li\u003e\n  \u003cli\u003eCompact overall length of 1-45\/64 inches (44.00 millimeters)\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.002 pounds — minimal added weight to a tool kit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 1.50 mm hex socket fasteners in metric applications.

Always de-energize and lock out electrical equipment before accessing internal fasteners on powered assemblies. Short-arm hex keys provide higher torque resistance than long-arm keys of the same size but offer reduced reach — confirm access geometry before use. Do not apply excessive force to small hex keys, as this can round the fastener socket or deform the key.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 1.50 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: 1-45\/64 inches (44.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Range\u003c\/strong\u003e: Less than 4 inches\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: 6.75 x 1.75 x 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.002 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: PAR37250\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARAMOUNT","offers":[{"title":"Default Title","offer_id":51538411946290,"sku":"PAR37250","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eb18cbc6b73c510af0e487da729c70b8.jpg?v=1785824594","url":"https:\/\/voomisupply.com\/products\/paramount-par37250-hex-key-1-50mm-short-arm","provider":"Voomi Supply","version":"1.0","type":"link"}
