Makita WR100DZ Ratchet Wrench 12v is supplied with a 1/4" and 3/8" socket adaptor. The WR100DZ can be used as a hand ratchet wrench. By removing the socket adapter, you can convert this model to a pass-through ratchet wrench, which is ideal for tightening 13mm nuts onto long threaded bolts such as a threaded rod.
