Allen wrench (Tapered Head®, extra long) set

Sizes are colored to be easily distinguishable and baked coating is luxurious and unlikely to peel off. 2.5-10 mm also come with a silk print size indication. 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°).
