12 piece metric combination spanner set featuring a typically Teng new design in combination spanners that provides an anti slip on the open end and a hip grip function where the spanner drives on the flank of the fastening rather than the corner. The design also provides grip on fastenings with worn or rounded corners. The combination of these features allow for a much better grip with less risk of damage to fastenings. The set is supplied in a unique Teng Tools TC tray and can be used either on it's own or as part of the Teng Tools TC control system. The tray features a removable hinged click lock lid and dove tail joints which enable different TC trays to be locked together and used as trays in Teng Tools tool boxes and roller cabinets. The tools are held in place using the Teng Tools two colour pre-cut EVA foam which has been computer milled to house each specific tool. The top layer of the foam is black and the bottom layer is red so that as soon as a tool is taken out, the shape of the tool is clearly visible. The EVA foam is also etched with the size or description of the tool next to it's position so that if a tool is missing not only can the space be clearly seen but the missing tool can be identified quickly. (265x284x50mm).
