1. Open End Wrench 

Slim Profile Wrenches

An open-end wrench is probably the most common wrench type in home and professional toolboxes. These types of wrenches feature double-sided U-shaped heads with different sizes on both ends, they work by touching only two sides of the fastener. One of the most important things in open-end wrenches is that they are slimmer than their cousin, box end wrenches, making them useful when dealing with hard-to-reach nuts. The Olsa Tools slim profile wrenches feature an open-end design that is thinner than regular open-end wrenches (under 5.5 mm) yet sturdy enough to withstand the strength that you need to complete the job efficiently, making it easy to get to bolts that are recessed. These wrenches exceed ASME code B107.100-2002 by 30%, so you can be confident that they are built with professional and heavy-duty use in mind.

2. Combination Wrench

Combination Wrenches

Combination wrenches deliver the versatility that any mechanic would love by combining both an open-end loop for hexagonal or square nuts and a box or closed-end profile in the same wrench. These two features fuse the best of both types of wrenches; delivering extreme power while loosening a stubborn bolt with the box end head, and easily getting into tight places with the open end head. The Olsa Tools Metric and SAE combination wrenches are also built using a convenient 12-point box end design that is engineered to avoid fastener round-off or slipping while you work, saving you time and frustration.

3. Adjustable Wrench

This type of wrench features a spiral screw that is embedded and opens or closes the crescent jaws as you turn it. This allows you to work on multiple tasks without needing to know the sizes of the fasteners that you’re working with. The jaws in the Olsa Tools adjustable wrench sets are wide so that you can work in a variety of jobs. Plus, the innovative patented low-rattle mechanism that will secure the adjustment to avoid changing the jaw size by accident when placing the wrench on surfaces, delivering frustration-free work and ensuring that you get the job done comfortably and efficiently during any heavy-duty situation!

4. Ratcheting Wrench

The Olsa Tools 12 pc ratcheting wrench set is engineered to work on 80% rounded nuts and bolts thanks to the ratcheting mechanism. In addition, the grooves on the open end head provide extra gripping power when you bite into the bolt and reduce the chances of rounding out fasteners.
