Allen wrench set (Tapered Head®, extra long, 9 pieces per set) (with pipe)

Pipe adapter developed exclusively for 2-stage holders can store 2 pipes comfortably without becoming unwieldy. Pipes are included, so it is ideal for retightening. Durability and wear resistance are further improved so that the Taper Head can be used for final tightening. The torsional strength is 10% to 20% higher than the conventional ball point, and especially effective when used at an inclination (0 to 20°).
