Forged from steel with a chrome-plated finish, this wrench features a 15-degree and 60-degree head angle on opposing ends, giving technicians two working positions from a single tool. The head width measures 1-13\/64 inches, providing solid contact on fasteners. At 0.22 pounds, it is lightweight enough for extended overhead or confined-space work without sacrificing durability. The chrome finish resists corrosion and makes the tool easy to wipe clean in the field.\u003c\/p\u003e\n\u003cp\u003eThis wrench is suited for residential and commercial service work across multiple trades. HVAC technicians use double-ended open end wrenches for refrigerant line fittings, equipment mounting hardware, and service valve access. Plumbers reach for them on supply line connections and fixture nuts. The dual-angle head design is especially useful in tight spaces where a single approach angle would be blocked by surrounding structure or adjacent components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e18 mm double-ended open head fits a single fastener size with two approach angles\u003c\/li\u003e\n  \u003cli\u003e15-degree and 60-degree head angles for access in restricted clearances\u003c\/li\u003e\n  \u003cli\u003eSteel construction with chrome-plated finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eHead width of 1-13\/64 inches for full-contact fastener engagement\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.22 pounds, suitable for extended or overhead use\u003c\/li\u003e\n  \u003cli\u003eMeets GGG-W-636E federal specification standard\u003c\/li\u003e\n  \u003cli\u003eBacked by a lifetime warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 18 mm open end wrench suitable for metric fasteners commonly found in HVAC equipment, plumbing fixtures, and general mechanical assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eUse by qualified service technicians in accordance with applicable trade standards. Ensure the correct wrench size is matched to the fastener before applying torque to prevent rounding. Inspect the chrome finish periodically for wear or chipping that could indicate the tool has been subjected to impact loads it is not rated for.
