Use the end style that fits the connection.
The 22-piece 81916 provides conventional metric combination wrenches. The 16-piece 9416 trades some size coverage for 72-tooth ratcheting box ends that work with a 5° swing. The six-piece 81906 is for suitable metric flare-nut connections. Compare the end style, actual sizes and clearance; these sets can complement one another rather than replacing each other.
Match the actual fitting size, access angle and material. Keep SAE requirements separate. Do not use serrated gripping pliers as an automatic substitute for a correctly fitting line wrench.

81916 22-piece metric combination wrench set
A combination-wrench set for fasteners where a socket is awkward to position or a second tool is needed to hold the opposite side. Size coverage and handle clearance are the useful starting points for comparing it.
Not a contiguous 6–32 mm set: 25, 26, 28, 29 and 31 mm are absent.
81906 six-piece metric flare-nut wrench set
A six-piece metric flare-nut wrench set for suitable line fittings. The wrench surrounds more of the fitting than an ordinary open-end spanner, but access and fitting condition still affect the job.
Use the correct metric opening and support the line fitting as the vehicle procedure requires. This set is not an SAE substitute.
16-piece metric ratcheting combination wrench set
Ratcheting combination wrenches reduce the need to lift and reposition the tool during suitable fastening work. They offer a different access trade-off from the larger conventional set and the dedicated flare-nut wrenches.
The 23 mm size is absent. Non-reversing heads need clearance to remove or turn the wrench over, so check the surrounding structure before backing a fastener out.
