Bessey Auto-Adjust Toggle Clamp, Inline Base Plate - 5/8 in. Capacity
Self-Adjusting Toggle Clamp for Fast, Consistent Clamping
Bessey® Inline Toggle Clamp with Flanged Base Plate
The BESSEY® Auto-Adjust Inline Toggle Clamp with Flanged Base Plate provides fast, secure clamping while automatically adapting to variations in workpiece height. Its self-adjusting design maintains consistent clamping force across different material thicknesses, making it an excellent choice for woodworking, jigs, fixtures, machining, assembly, and both small- and large-scale production environments.
Designed to offer greater flexibility than traditional toggle clamps, this inline toggle clamp combines automatic adjustment, variable clamping force, and a durable construction for reliable performance. The flanged base plate provides convenient mounting options, while the ergonomic handle makes repeated clamping comfortable and efficient.
Automatic Adjustment for Different Workpiece Heights
The integrated auto-adjusting mechanism compensates for changes in workpiece thickness while maintaining the desired clamping force. This makes the clamp especially useful for production setups where multiple workpieces may vary slightly in height. Less manual adjustment means faster setup and more consistent results.
Adjustable Clamping Force
An integrated clamping force adjustment screw allows the user to control the amount of pressure applied to the workpiece. The nominal clamping force range is approximately 25 to 250 lbs., depending on spindle settings, pressure screw adjustment, and the force applied by the operator.
Inline Design with Flanged Base Plate
The inline configuration is well suited for applications where a compact clamping solution is needed along the same line as the workpiece. The flanged base plate provides a stable mounting surface and flexible installation options for custom jigs, fixtures, workholding systems, and production tooling.

Ideal for Jigs, Fixtures, and Production Workholding
The Bessey® Inline Auto-Adjust Toggle Clamp is a practical solution for applications that require repeatable, secure workholding. Use it to hold components in woodworking jigs, assembly fixtures, drilling fixtures, machining setups, and production workstations. Its automatic adjustment helps streamline workflows when workpiece dimensions vary, while the adjustable clamping force provides greater control over how firmly each piece is held.
*Clamping force is variable and dependent on spindle settings, pressure screw settings, force applied, and other operating conditions. Small spindle adjustments may be required to achieve maximum clamping opening.

Proposition 65 (formally titled "The Safe Drinking Water and Toxic Enforcement Act of 1986") is a California law that has been in effect since 1986 to promote clean drinking water and keep toxic substances that cause cancer and birth defects out of consumer products. It is administered by Cal/EPA's California Office of Environmental Health Hazard Assessment (OEHHA). Proposition 65 regulates substances listed by California as causing cancer or birth defects or other reproductive harm in two ways. The first regulatory arm of Proposition 65 prohibits businesses from knowingly discharging listed substances into drinking water sources, or onto land where the substances can pass into drinking water sources. The second regulatory arm of Proposition 65 prohibits businesses from knowingly exposing individuals to listed substances without providing a clear and reasonable warning.
BESSEY branded products do not, to the best of our knowledge, expose individuals to harmful substances as listed by the Cal Prop 65 Legislation.
WARNING: Drilling, sawing, sanding or machining wood products can expose you to wood dust, a substance known to the State of California to cause cancer. Avoid inhaling wood dust or use a dust mask or other safeguards for personal protection. For more information go to www.P65Warnings.ca.gov/wood.
