OTC 1914 4" 6-Point Hexagon Locknut Wrench
Wheel bearing locknuts are easy to remove or install with these specially designed sockets. They’re made of high strength steel and resist rounding out. Measure from flat side to flat side of locknut to determine size needed. Note: Sockets are designed for use with 3/4 inch square-drive manual tools only. Impact tool use voids sockets’ warranty.
