These Teng Tools ratcheting spanners combine an open ended spanner with a 72-tooth 12-point ring ratchet. The ratchet has a 'flip reverse' feature, which switches the direction of the ratchet, and the head is offset at a 13° angle for ease of access. Both ends are of the same size.

The spanners are made from chrome vanadium steel with a satin finish.

The TENTT6508R 8-piece set contains the following sizes:
8mm, 10mm, 11mm, 12mm, 13mm, 14mm, 17mm and 19mm.
