Speed, access, strength and safety are the most important factors when it comes to the performance of a wrench. The Armstrong geared box wrench is designed to give you all four without compromising any one factor. This unique combination allows you to perform tasks that, in the past, have required the use of both ratcheting box wrench and traditional box wrenches. The 72-tooth design provides a smooth, controlled ratcheting action. These wrenches are a necessity in today’s industrial and automotive shops.
