Socket Head Screws

Torque Screwdrivers

Apply precise torque as you fasten screws to prevent overtightening

Socket Head Screws

Torque Screwdriver and Bit Sets

These sets include an adjustable torque driver, bits for different drive styles, and a socket adapter.

Socket Head Screws

Torque Screwdrivers

Set the desired torque and the driver indicates when it's reached.

Socket Head Screws

Static-Control Torque Screwdrivers

Also known as ESD-safe screwdrivers, the handle drains static away from your application, preventing buildup from electrostatic discharge (ESD) that can damage sensitive equipment. When set torque is reached, these drivers slip to disengage and prevent overtightening.

Socket Head Screws

Electrical-Insulating Torque Screwdrivers

An insulated handle and shaft protect against shock from accidental contact with live electrical circuits. These tools are tested to 1,000 volts to meet IEC 60900 standards. When set torque is reached, these drivers signal with an audible click.

Socket Head Screws

Changeable-Shaft Torque Screwdriver Sets

Set includes a handle and six shafts. Remove and replace the shaft to use a different size or drive style.

Socket Head Screws

Changeable-Shaft Torque Screwdrivers

Choose a handle based on torque, and a shaft with the size you need.

Socket Head Screws

Square-Drive Torque Screwdrivers

Attach a socket to the 1/4" square drive tip to turn hex nuts and hex head screws. When set torque is reached, these drivers signal with an audible click.

Socket Head Screws

Factory-Set TorqueScrewdrivers for Carbide Inserts

Ensure carbide inserts are tightened to the correct torque. These tools are set to the recommended torque values for each screw size.

Socket Head Screws

Factory-Set Torque Screwdriversfor High-Volume Assembly

Also known as impact-free torque screwdrivers, these tools minimize reaction force when the set torque is reached. They reduce user fatigue when installing many fasteners in a short period of time.

Socket Head Screws

Factory-Set Torque Screwdrivers

Reach the same torque every time with factory-set screwdrivers that slip to disengage and stop turning the fastener when the set torque is reached, preventing overtightening.

Socket Head Screws

Socket Head Screws

Electric Torque Screwdrivers

Set torque and the clutch slips to prevent you from exceeding it.

Socket Head Screws

High-Precision Electric Torque Screwdrivers

The motor shuts off when the set torque is reached to prevent overtightening and damaging fasteners. These tools provide the most torque control of any electric screwdriver.

Socket Head Screws

Torque-Measuring Screwdrivers

A dial shows how torque measurements change as you turn the driver. Use these tools to fasten to a specific torque, determine fastener torque specifications, and identify the torque required to loosen tightened fasteners.

Socket Head Screws

Square Drive Torque-Measuring Screwdrivers

Attach a socket to the 1/4" square drive tip. These tools have a dial that shows how torque measurements change as you turn the driver. Use to fasten to a specific torque, determine fastener torque specifications, and identify the torque required to loosen tightened fasteners.

Socket Head Screws

Digital Torque-Measuring Screwdrivers

A green light and a beep alert you when you've reached 90% of your set torque, and a steady tone sounds once you've hit your target. Set your torque in cNm, cm-Kg, or in.-lbs. and quickly check the LCD for real-time measurements along the way. A red light warns if you begin to overtighten.

Socket Head Screws

High-Precision Air-Powered Torque Screwdrivers

The motor shuts off when the set torque is reached to provide the most torque control of any air-powered screwdriver.
