Description of GearWrench 85818 X Beam Combination Ratcheting
X-Beam allows you to apply force to the flat reducing hand fatigue. Up to 525% increase in surface contact area. Up to 25% longer to access those hard to reach areas. Surface drive plus: provides stronger grip on fasteners, reduces fastener rounding, delivers up to 25% more torque. Metric.
I love all GearWrench ratchets. I have a set of flex heads but it jumps from 17 to 19 and now I need 18mm twice in a row. The X-Beam style is extremely comfortable and easy to use.
