It is machined from Protanium High Torque Steel, a material engineered to resist rounding and torsional failure under heavy load. The overall length measures 6-19\/64 inches, and the hex end engages fasteners directly without an intermediate socket or adapter. This tool is used by HVAC technicians, plumbers, electricians, and mechanical contractors whenever a hex-drive fastener must be seated or broken loose in a confined area.\u003c\/p\u003e\u003cp\u003eThe short-arm configuration makes this key well-suited to panel interiors, equipment access compartments, and anywhere a long-arm tool would foul on surrounding structure. The 5\/8 inch hex size covers a range of heavy-duty fasteners commonly found on commercial HVAC equipment, pump housings, valve bodies, and mechanical assemblies. A gray handle aids visual identification in a tool pouch. Single-piece construction with no moving parts means no maintenance between uses.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/8 inch hex size for large-format hex-drive fasteners\u003c\/li\u003e\n\u003cli\u003eShort-arm style provides clearance in confined or restricted spaces\u003c\/li\u003e\n\u003cli\u003eProtanium High Torque Steel resists torsional failure and fastener rounding\u003c\/li\u003e\n\u003cli\u003eOverall length of 6-19\/64 inches keeps the tool compact without sacrificing leverage\u003c\/li\u003e\n\u003cli\u003eHex end type engages fasteners directly for positive drive\u003c\/li\u003e\n\u003cli\u003eGray handle for quick identification in a multi-tool pouch\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose short-arm hex key for use with any 5\/8 inch hex-drive fastener in industrial, commercial, or mechanical service applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is used by licensed mechanical, HVAC, and plumbing technicians across service and installation work. Always de-energize or lock out equipment before accessing internal fasteners on powered systems. Ensure the hex end is fully seated in the fastener socket before applying torque to avoid cam-out or fastener damage. Inspect the key for wear or deformation before each use on critical fasteners.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 5\/8 inch\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: 6-19\/64 inches (6.3 inches decimal)\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\u003ePackage Dimensions\u003c\/strong\u003e: 8 inches L x 5 inches W x 2 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.85 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27111710\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: PAR37218\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARAMOUNT","offers":[{"title":"Default Title","offer_id":51541029945650,"sku":"PAR37218","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d3ecf9be7fba4d81d0311837a3887b02.jpg?v=1785867535","url":"https:\/\/voomisupply.com\/products\/paramount-par37218-hex-key-5-8-inch-short-arm","provider":"Voomi Supply","version":"1.0","type":"link"}
