Automatic Bolt Drivers & Bolt Feeding
We build automatic drive heads and bolt feeding systems that can be integrated into your assembly process.
Why use a Carlson Engineering & Manufacturing bolt driving + feeding system in your production process?
Simple – our advanced line of automatic bolt feeders and bolt drivers have the ability to integrate into dozens of different manufacturing industries globally, and can be used to increase production while lowering overhead.
- Our bolt driving product family can drive bolts to depth or torque, with torque ranges between 1 Nm and 1,000+ Nm.
- Using a servo or a fixtured positioning system, our bolt drivers can be articulated to work perfectly on complex applications.
- All of our bolt drivers come standard with high-quality linear guide bearings for a long life, meaning your investment will last for years to come.
- Our 3-step fastener alignment verification process means our bolt drivers can operate for hours without maintenance or errors.
- Carlson bolt feeding systems have minimal pinch points and can be fully enclosed for advanced levels of safety in operation.
- Our standard polyethylene bowl coating prevents abrasion on fasteners, meaning less damage to the end product due to the manufacturing process.
Like our screw feeders, Carlson bolt feeding systems are engineered to work non-stop without jams, errors, and with minimal maintenance.
Because you don't have time to sit around and wait for jams to be fixed.
With our years of experience in engineering custom bolt feeding solutions for manufacturers across a wide range of industries, we have developed a simple, 3-step process that virtually eliminates bolt jams along the track – meaning your assembly process doesn’t have to get slowed down.

Step 1: Sorting Air Jet
The first step in our 3-step fastener verification is our Non-Adjustable Sorting Air jet – a highly pressurized stream of air that ejects misaligned bolts from the track - our first line of defense.

Step 2: Qualifying Track Cover:
The second step is a Non-Adjustable Bowl Track Qualifying Cover, which prevents misaligned bolts from passing underneath its clearance and moving down the escapement track in the first place.

Step 3: Optic Sensor
When the optic sensor notices that the escapement is full of bolts, the step feeder's bolt elevator will stop lifting bolts to the track. This prevents back pressure and jams in the feeder tray.
Carlson Engineering bolt driver products.
All of our automatic drive heads can be configured to drive bolts instead of screws.
Below, you will find examples of our top Handheld automatic bolt driver models, fixtured bolt driver models, multi-spindle bolt driver models, and our CoBot-compatible bolt driving end effectors.
