Knevelspanner BESSEY STC-VH50

The BESSEY STC-VH50 toggle clamp provides a reliable clamping solution with a 4 cm clamp opening and compact, ergonomic construction. Built from durable materials including stainless steel components and finished in a black and red design, this toggle clamp is engineered for frequent use in workshop and production environments. With a weight of 430 g, it delivers solid holding force while remaining easy to position and operate on jigs, fixtures, and workbenches.

Advantages

This toggle clamp combines corrosion-resistant stainless steel parts with a sturdy mechanism that maintains clamping force under repeated cycles. The 4 cm opening accommodates a range of workpiece thicknesses and the compact footprint allows mounting in tight spaces. The clamp’s lever and handle geometry are designed for straightforward manual operation, enabling quick locking and release without additional tools.

Suitable for

• Holding small to medium workpieces during machining, drilling, or sanding
• Fixture and jig assembly in woodworking and metalworking
• Securing parts for inspection, gluing, or welding
• Use in hobbyist and light industrial production settings

Key specifications

• Clamp opening: 40 mm
• Material: stainless steel components with additional durable metal parts
• Weight: 430 g
• Finish: black and red
• Mounting: designed for fixed mounting on jigs and fixtures (mounting holes on base)

How to use

Mount the toggle clamp securely to a flat surface or jig using appropriate fasteners through the base mounting holes, ensuring alignment with the workpiece. Position the workpiece within the 40 mm opening, then depress the handle to engage the toggle mechanism and apply stable clamping pressure. To release, lift or move the handle according to the clamp’s travel path until the mechanism unlocks and the workpiece can be removed. Regularly check fasteners and alignment to maintain consistent clamping performance.

Recommendations

For long-term performance, keep moving parts clean and periodically inspect for wear or corrosion. Use appropriate mounting hardware for the substrate material and avoid exceeding the intended workpiece thickness or clamping force for this size of toggle clamp.
