How It Works

Service wrenches, also sometimes known as engineer’s wrenches, are short-handled open-end wrenches that are thinner than a typical combination wrench. Similar to check nut wrenches, these products are well-suited for lower torque applications with limited access, such as hydraulic system maintenance or machinery repairs and adjustments.

T: Service Wrench Features

To reduce the working swing arc in tight spaces, the open end is angled 15 degrees so the wrench can be flipped over with each rotation to engage the fastener twice as often.

Angled Open End

The service wrenches are designed to be considerably thinner than traditional combination wrenches in order to increase your access options.

The service wrenches have a shorter handle than most other types of full-size wrenches in order to offer increased versatility and access into tight spaces.

Versatile, Short Handle

Connect drive tools, such as torque wrenches, using the square 3/8 inch drive hole on the end of every wrench.

LaserMill Manufacturing

An oiled black oxide finish helps protect the wrenches from corrosion. Each wrench is permanently laser-engraved with its size and, to assist with torque conversions, the length from the center of a fastener to the center of the drive end.

Finish and Markings

The Service Wrenches are made entirely within the USA, with many of the steps taking place at our West Michigan headquarters, using our proprietary LaserMill process:

When using a service wrench, or similar tools, with a torque wrench, you may need to adjust your settings to make sure you’re applying the proper torque.
