GearWrench Indexing ratcheting wrenches need as little as 5-Degree to move the fastener as opposed to 30-Degree for standard box end wrenches. Patented indexing technology allows you to pick the angle you need depending on the situation. Just a push of the indexing button allows you to select 13 different angles. The box end features improved strength from GearWrench Surface Drive technology and at the same time, reduces fastener rounding. These ratcheting wrenches are made from premium alloy steel for a precision, long lasting tool.
