2Pcs 1/2" X 9/16" SAE 25 Degrees Double Head Hvac Service Wrench

The ratchet wrench is made of CR-V with high strength and high wear resistance, which is very suitable for tightening screws or nuts without worrying about breaking easily. The surface is chrome plating to ensure durability and corrosion resistance, extending service life. Ratchet spanner allows the screwdriver to quickly switch between tightening and loosening, just flip the direction adjustment buckle to switch between clockwise and counterclockwise rotation. The curved design is suitable for narrow spaces, and the wrench applies more torque to tighten or loosen any bolt without rounding. The service wrench is designed for hard to reach compressor service valves, oil check plugs on compressors, air conditioning, refrigeration units, equipment repairs, valve stems and service valves, saving your knuckles and time. Please choose a double-ended wrench that matches the size of the screw or nut to avoid damage or slippage; when applying torque, make sure the angle of the wrench is aligned with the bolt or nut for better force transfer and operation.
