It features a 12-point ratcheting box end with a 15-degree offset head, allowing incremental fastener rotation without repositioning the wrench. The open end provides quick nut engagement, while the ratcheting box end handles final torquing. At 9-5\/16 inches overall length and 0.46 pounds, it strikes a practical balance between reach and hand fatigue. The chrome finish provides corrosion resistance for daily shop and field use. It is tether capable, making it suitable for work at height or over open equipment where dropped tools are a safety concern.\u003c\/p\u003e\u003cp\u003eThis wrench is suited for mechanical, HVAC, plumbing, and electrical tradespeople working on equipment fasteners in the 18 mm metric range. The ratcheting box end speeds up repetitive fastener tasks in confined spaces where a full-swing wrench is impractical. It applies in residential and commercial service work wherever metric fasteners appear on equipment, panels, or structural hardware. The straight handle and 15-degree head offset help clear obstructions common in equipment bays and mechanical rooms.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRatcheting 12-point box end for fast, incremental turns in confined spaces\u003c\/li\u003e\n\u003cli\u003e15-degree offset head angle clears obstructions without repositioning\u003c\/li\u003e\n\u003cli\u003eTether capable design meets dropped-tool safety requirements for work at height\u003c\/li\u003e\n\u003cli\u003eChrome finish provides corrosion resistance for field and shop environments\u003c\/li\u003e\n\u003cli\u003eMeets ASME standards for combination wrenches\u003c\/li\u003e\n\u003cli\u003eLifetime warranty coverage from the manufacturer\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 18 mm combination wrench for use with metric fasteners across mechanical, HVAC, plumbing, and electrical service applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eLicensed tradespeople and service technicians should power down or de-energize equipment before using hand tools on fasteners near live components. Attach tether hardware per site safety requirements when working over open machinery or at elevation. Inspect the wrench for cracks or worn points before use and replace if the ratchet mechanism shows slippage. Consult applicable codes such as OSHA 29 CFR 1926 for dropped-tool requirements at elevated work sites.\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\u003eOverall Length\u003c\/strong\u003e: 9-5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Offset Angle\u003c\/strong\u003e: 15 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Points\u003c\/strong\u003e: 12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRatcheting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Offset\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\u003eFinish\u003c\/strong\u003e: Chrome\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTether Style\u003c\/strong\u003e: Tether Capable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorrosion Resistant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNon-Sparking\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMagnetic\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.46 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: Lifetime\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: JSCRM18\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51538738250034,"sku":"JSCRM18","price":42.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9f29e1d05e3019790d0606b6890a9392.jpg?v=1785825903","url":"https:\/\/voomisupply.com\/products\/proto-jscrm18-combination-wrench-18-mm-ratcheting","provider":"Voomi Supply","version":"1.0","type":"link"}
