Built from corrosion-resistant steel with a 15-degree offset head, it provides clearance over obstructions while maintaining positive engagement on 18 mm fasteners. The open end and box end are combined in a single tool, giving technicians two drive options without a tool change. At 5.25 inches overall length and 0.29 pounds, it is sized for tight-access work. The tether-capable design supports use in elevated or confined environments where dropped tools are a safety concern. Meets ASME B107.100-2010 standards.\u003c\/p\u003e\u003cp\u003eThis wrench is suited for HVAC equipment assembly, mechanical contractors, industrial maintenance crews, and utility technicians working on machinery, piping supports, and structural fasteners. The 18 mm head size addresses metric hardware commonly found on commercial equipment, imported machinery, and modern HVAC and refrigeration systems. The straight handle and offset box end make it a reliable daily-carry tool for technicians working from ladders, elevated platforms, or inside confined equipment panels where dropped-tool prevention is required by site safety protocols.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e18 mm head size fits standard metric fasteners on commercial and industrial equipment\u003c\/li\u003e\n\u003cli\u003e12-point box end allows engagement in 30-degree increments for use in restricted swing areas\u003c\/li\u003e\n\u003cli\u003e15-degree offset head provides knuckle clearance and access over obstructions\u003c\/li\u003e\n\u003cli\u003eTether-capable design supports dropped-object prevention programs on elevated work sites\u003c\/li\u003e\n\u003cli\u003eCorrosion-resistant steel construction for durability in field and shop environments\u003c\/li\u003e\n\u003cli\u003eMeets ASME B107.100-2010 standard for combination wrenches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style hand tool replacement or addition for professional tool kits requiring an 18 mm metric combination wrench with tether capability.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis wrench is installed and used by licensed mechanics, HVAC technicians, plumbers, and industrial maintenance professionals. Before applying torque to system fasteners, confirm the system is de-energized or depressurized as required by applicable safety procedures. Use with an appropriate tether anchor point when working at height in compliance with site dropped-object prevention requirements. Do not use extensions or pipe over the handle to increase leverage beyond the tool's rated design.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Size\u003c\/strong\u003e: 18 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Points\u003c\/strong\u003e: 12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Offset Angle\u003c\/strong\u003e: 15 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Thickness\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandle Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorrosion-Resistant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTether Style\u003c\/strong\u003e: Tether Capable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNon-Sparking\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRatcheting\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.29 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 6.77 inches L x 2 inches W x 0.5 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B107.100-2010\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27110000\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PROTO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: J1218MESB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51539510165810,"sku":"J1218MESB","price":32.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a1de28a7c6a1078ea09de75c564f45a6.jpg?v=1785842181","url":"https:\/\/voomisupply.com\/products\/proto-j1218mesb-combination-wrench-18-mm-12-point","provider":"Voomi Supply","version":"1.0","type":"link"}
