The 97BTX Series Torx® keys from Beta Tools are designed for professional use. The burnished black oxide finish looks great and lasts a lifetime. The short leg and the extended leg of the L-handle both have the same Torx drive size. The extended leg has a "ball" profile to allow up to 30 degrees of misalignment with the fastener. This can help with access in tight areas, but it also makes it easier to spin the key between your fingers.This set includes a brilliantly-engineered folding case that locks all the keys in place when you snap it closed. This can also be purchased alone, select from the drop down list.
The heart of this clever case is a molded strip on the inside of each half. Closing the case forces the strips against the keys to positively lock them in place. When you open the case, pressure is released and the case acts like an ordinary holder.
This set includes the following 8 ball head, offset metric sizes:T9, T10, T15, T20, T25, T27, T30, T40 Dimension Table:
