Metric Crowfoot Spanner With Tommy Bar

A metric crowfoot spanner with a Tommy bar refers to a set of crowfoot spanners with metric sizes that includes a Tommy bar or Tommy bar handle as an accessory. A crowfoot spanner is a specialized tool used to tighten or loosen fasteners in tight spaces or on tubing connections where a traditional wrench or socket cannot fit. It features a C-shaped or U-shaped opening on one end that fits over the flats of a fastener. The Tommy bar is a long metal bar that can be inserted into the square drive hole or hexagonal opening on the crowfoot spanner. It provides additional leverage, allowing for increased torque when turning the spanner and making it easier to tighten or loosen fasteners.
