Torque Screwdrivers

Torque screwdrivers are used to apply a set level of torque to screws, nuts, bolts and other fasteners.

We offer a wide range of electric torque screwdrivers, air torque screwdrivers, preset torque screwdrivers, adjustable torque screwdrivers and ESD safe torque screwdrivers.

Frequently Asked Questions about Torque Screwdrivers

What is a torque screwdriver?

A torque screwdriver applies a specific amount of torque to screws, ensuring they are not over-tightened or under-tightened. This precision prevents damage to components and ensures assemblies are secure.

What are the differences between manual, electric and pneumatic torque screwdrivers?

Manual torque screwdrivers are user-powered and suited for occasional use. Electric models provide consistent torque for high-volume tasks, while pneumatic options deliver higher torque for industrial jobs.

How do I select the appropriate torque screwdriver for my needs?

Consider the torque range required, the type of screws you’ll work with and whether you need a manual, electric or pneumatic model. Ergonomics and compatibility with existing tools are also important.

Can a torque screwdriver be used for all screws?

Torque screwdrivers can handle a variety of screws, but it’s crucial to use the correct torque setting and bit type for the screw and material to avoid damage.

Why is it important to calibrate a torque screwdriver?

Calibration ensures the tool applies accurate torque, which is critical for maintaining assembly quality. Calibrate annually or after a specific number of uses, as recommended by the manufacturer.

Are torque screwdrivers suitable for electronics or delicate assemblies?

Yes, torque screwdrivers are ideal for electronics and precision assemblies where overtightening can damage sensitive components. Low-torque models are specifically designed for such applications.

What bit types are compatible with torque screwdrivers?

Torque screwdrivers typically accept standard 1/4-inch hex bits (although in some rarer cases HIOS, D-CUT or square drives are required), including Phillips, slotted, Torx and hex. Always ensure the bit matches the screw head for optimal grip and torque transfer.

How should I store my torque screwdriver?

Store the tool in a clean, dry case and set it to the lowest torque setting after use to relieve tension. This helps preserve the accuracy and longevity of the internal mechanism.
